Work IQ will be able to invoke custom agents and agents that call supported third-party tools. Preview Oct 2026, release Nov 2026, Web, Worldwide (Standard Multi-Tenant) (roadmap 570853).
Why it matters: Work IQ stops being read-only grounding and starts calling customer-built agents, which puts third-party tool calls inside the Work IQ trust boundary.
microsoft.com
Context IQ expands so users can discover and select additional agents, skills and content sources while composing a prompt. Preview Oct 2026, release Nov 2026, Web, Worldwide (Standard Multi-Tenant) (roadmap 570854).
Why it matters: More selectable sources at prompt time means the grounding surface users can reach needs reviewing against existing DLP scope.
microsoft.com
Tools management in Agent 365 is now generally available and reaches beyond MCP servers to plugins, skills and connectors. From one pane admins discover connected tools, review key metadata and usage, and apply tenant-wide allow or block controls across all four types. Power Platform connectors governance is still in progress.
Why it matters: One allow/block surface for every tool type replaces chasing plugin and connector governance through separate admin centers.
techcommunity.microsoft.com
Cost management in Agent 365 expands beyond Copilot Cowork and Work IQ and now supports Code and Copilot Managed Runtime. Support for agents built with Microsoft Copilot Studio is planned for October, with more AI workloads to follow.
Why it matters: Usage-based spend for the new Copilot surfaces lands in one place, and Copilot Studio agents join it next month.
techcommunity.microsoft.com
The Consumption Dashboard in Insights shows trends across active users, credits and tasks, organizes work by task category, and estimates Cowork-assisted value in time and dollars.
Why it matters: It supplies the usage-to-value numbers that Copilot business cases normally have to be reconstructed by hand.
techcommunity.microsoft.com
In public preview, admins create rules in the Microsoft 365 admin center that automatically block agents, reject publication requests or apply policy templates when conditions are met. Criteria include ownership status, agent tags, Microsoft Entra Agent ID, publisher, risk signals and usage activity.
Why it matters: Governance scales with agent count instead of per-agent admin review, and unowned or untagged agents can be blocked on arrival.
techcommunity.microsoft.com
In public preview in September 2026, developers register custom MCP servers through the Agent 365 CLI and submit them for administrator review before agents may invoke them. In the Microsoft 365 admin center the admin inspects the server description, publisher, requestor, endpoint and capabilities, then approves or rejects.
Why it matters: Custom MCP servers get a documented submission route, so partner tooling can ship into a tenant without a standing exception.
techcommunity.microsoft.com
Beginning September 30 the Agent 365 and Azure API Management integration starts rolling out. AI assets onboarded to API Management - agents, tools, models and MCP servers - are automatically discovered in Agent 365, while API Management applies authentication, routing and runtime controls to AI traffic.
Why it matters: Inventory stops depending on manual onboarding, and runtime enforcement sits in front of the agent rather than only in policy.
techcommunity.microsoft.com
When configuring a spending policy in cost management, admins can give different groups access to specific models and effort levels. The policies also shape which models Auto can select in Cowork. Rolling out for Cowork, with additional workloads planned.
Why it matters: Advanced models can be reserved for the groups that justify them without blocking everyone else's Cowork access.
techcommunity.microsoft.com
Model router is now available in 32 Azure regions, adding Canada Central, North Europe, Norway East and UAE North. North Europe and Norway East support both Global Standard and Data Zone Standard deployments; Canada Central and UAE North support Global Standard deployments only.
Why it matters: North Europe and Norway East gaining Data Zone Standard is the first model-router option that keeps routing inside an EU data zone; there is still no Switzerland region in the list.
learn.microsoft.com
Chat Completions applications can supply an opaque session ID to ask model router to attempt the same eligible model across related conversation turns. Existing eligibility and fallback behavior is preserved, and the response reports whether a request initialized, retained or switched the model association.
Why it matters: Multi-turn conversations stop silently changing model mid-thread, which is what made routed deployments hard to evaluate.
learn.microsoft.com
Clients that opt in to the preview response contract get observability metadata on each Chat Completions response: routing mode, routing-trace latency, ordered model attempts, HTTP status and returned errors. Multiple attempts reveal when automatic fallback occurred.
Why it matters: Cost and latency anomalies in a routed deployment become attributable per request instead of only visible in aggregate.
learn.microsoft.com
New APIs on the Business Central report inbox let report outputs be automated with Power Automate or MCP. GA Oct 2026 (roadmap 573318).
Why it matters: Report delivery becomes a flow or an agent tool call, removing a common custom-code step in BC implementations.
microsoft.com
New or existing custom Dataverse fields can be mapped directly from the Integration Table Mappings page: refresh the Dataverse field list, add the field to an existing mapping, pick the Business Central field, set the sync direction and enable it. Previously this required creating or updating a table extension in the integration layer. GA Oct 2026 (roadmap 573365).
Why it matters: Dataverse schema changes stop requiring an AL deployment, which shortens the change cycle on BC and Dynamics 365 Sales integrations.
microsoft.com
OneDrive for the web moves the Create or upload button from the left navigation pane to the right side of the page, matching SharePoint document libraries. The options for creating files and folders or uploading content are unchanged. GA Oct 2026 (roadmap 572683).
Why it matters: A visible change to the most-used OneDrive control is worth a line in end-user comms and a check of any internal screenshots.
microsoft.com
Exchange Online EWS changes start landing between October 2026 and April 2027. Two scenarios hit on-premises customers: hybrid organizations with mailboxes both on-premises and online must move rich coexistence lookups such as free/busy and MailTips to Graph, which requires at least the May 2026 update for Exchange SE because only Exchange SE can use Graph for this; and two Exchange Online organizations sharing free/busy through org relationships move to Cross-Tenant Access Policy. Two Exchange on-premises organizations using org relationships with each other need no change at this time. On-premises mailboxes with archive mailboxes in Exchange Online are not fully supported yet, with support expected in following months.
Why it matters: Hybrid customers have a hard April 2027 deadline and a server-update prerequisite, and the unsupported on-premises-plus-cloud-archive case needs flagging in migration plans now.
techcommunity.microsoft.com
From September 30 all eligible partners can earn the Frontier Partner specialization, which validates designing, building, deploying, governing and securing AI agents across Microsoft 365 Copilot, Azure AI Foundry, GitHub Copilot, Defender, Entra and Purview, and carries a customer-facing badge, Frontier co-sell eligibility, Microsoft Agent pre-purchase plan (P3) credits and Microsoft 365 E7 licensing.

A new Microsoft 365 admin center option under Copilot > Settings pins the Microsoft Copilot app to the Windows taskbar for chosen user groups instead of all devices. It only pins on eligible Intune-managed Windows devices where the app is already installed, and rolled out worldwide in late September 2026.
Why it matters: A rollout can start with a champions group and widen from there, so taskbar placement follows the adoption plan instead of landing on every device at once.
m365admin.handsontek.net
Teams admin center will surface Teams apps and agents matching third-party applications already in use, such as ServiceNow, Workday and Jira, ranked by usage signals. Admins activate the feature and choose whether to enable each app for the users already using it, specific groups, or the whole organization; nothing changes automatically. Targeted Release and general availability (Worldwide, GCC) both run early to mid November 2026.
Why it matters: Turns app-catalog decisions into a usage-driven shortlist, which makes a Teams agent rollout easier to justify to a customer.
m365admin.handsontek.net
Fable 5.1 is now listed in the Cowork model selector as the most advanced model for ambitious work, taking over from Fable 5.
Why it matters: The top-end model slot changed, so guidance or training that names Fable 5 needs updating.
learn.microsoft.com
Plugins can be found and configured from the Microsoft 365 Copilot mobile app through the attach menu (+) > Skills.
Why it matters: Plugin setup no longer needs the desktop or web client, removing a blocker for mobile-first users.
learn.microsoft.com
Cowork can edit Office files already stored in OneDrive and SharePoint, preserving the shared file and its existing version history rather than producing a copy.
Why it matters: Keeps Cowork output inside existing document workflows and audit trails instead of spawning parallel files.
learn.microsoft.com
The Frontier early-access agent that turned Microsoft 365 Copilot conversations into draft SharePoint pages and news posts retires from mid-October 2026, completing mid-November 2026. Page and news authoring moves to Copilot in SharePoint inside the SharePoint authoring experience; pages already created stay accessible and need no migration.
Why it matters: Users who start page drafts from a Copilot chat lose that entry point and must author from SharePoint, so runbooks and training need reworking before mid-November.
m365admin.handsontek.net
Connected platforms in Agent 365 now pulls activity from Amazon Bedrock Classic and AgentCore, Google Vertex AI and Anthropic Claude Managed Agents (preview) into the same observability surface as Microsoft agents, showing runs, sessions, tool calls and exceptions on each agent's Activity tab. Targeted Release ran in late September 2026; general availability begins late October 2026 and is expected to complete by Ignite 2026.
Why it matters: One console covers agents across clouds, so a multi-vendor agent estate can be monitored without a separate tool per platform.
m365admin.handsontek.net
Microsoft paused automatic updates to Teams app version 1449/1.0.94.2026220406 on Teams phones after finding the build disables Advanced Calling on Common Area Phone devices. The pause is active globally; devices already on that version stay affected until a corrected build ships, and admins can still push the version manually from the Teams admin center.
Why it matters: Devices already updated have lost Advanced Calling, so check Common Area Phone versions before running any manual update.
m365admin.handsontek.net
Newly created Viva Engage communities now have the Microsoft 365 group settings for member email and calendar subscriptions enabled by default, so members receive community emails and calendar invitations without opting in. Community owners can change this in the My Account portal. Rollout completes by mid-October 2026; existing communities follow later this autumn.
Why it matters: New communities generate mailbox and calendar traffic from day one, which changes what to expect during an Engage launch.
m365admin.handsontek.net
Organizations that authenticate Microsoft 365 users through an external identity provider can now extend browser-based passkeys, security keys and eligible single sign-on sessions to Outlook, Teams, OneDrive, Word, Excel, PowerPoint and Microsoft To Do on Android, iOS and managed macOS. The external provider's sign-in step opens in the system browser instead of an embedded web view, then returns to the Microsoft identity broker. Applies to tenants federated through WS-Fed or SAML 2.0.
Why it matters: Removes the embedded web view limitation that blocked sign-in where an identity provider required passkeys, so a phishing-resistant rollout can cover the M365 mobile apps.
techcommunity.microsoft.com
The visual investigation view linking impacted data, users and alert activity is being removed: configuration was already withdrawn in early September 2026, new onboarding ended September 24, and retirement runs from early December to full removal on December 8, 2026. Investigators move to Activity explorer, Content explorer and User activity. Applies to Worldwide, GCC, GCC High and DoD.
Why it matters: Insider-risk investigation playbooks that screenshot or reference the graph need rewriting against the explorer views before December 8.
m365admin.handsontek.net
Retirement of both classic Data Security Posture Management experiences starts November 30, 2026 and completes by December 31, 2026, with capabilities folded into a single current DSPM experience covering traditional data sources plus AI applications and agents. Applies to Worldwide, GCC, GCC High and DoD.
Why it matters: Any DSPM for AI reporting built on the classic portal view stops working at the end of the year, so Copilot data-risk reporting has to be rebuilt on the unified experience.
m365admin.handsontek.net
A Content Security Policy on login.microsoftonline.com will allow only trusted Microsoft-hosted scripts during authentication, blocking externally injected code as part of the Secure Future Initiative. General availability runs worldwide from mid-October to late October 2026. Entra External ID tenants are not affected. Restated from MC1191924.
Why it matters: Browser extensions, monitoring or branding tools that inject script into the sign-in page will break, so inventory them before mid-October.

TomTom is publishing its location and geospatial data into Microsoft Fabric and Microsoft Foundry through the IQ Sharing preview, so agents can combine it with enterprise data in OneLake.

Excel Agent helps you turn data into clear charts, summaries, and insights using built‑in formulas and logic. It streamlines data preparation, formulas, and visualization so you can stay focused on the story behind the numbers. Use multi‑turn chat to refine your output or open it in Excel for full editing and collaboration. Ideal for financial forecasts, project plans, and decision‑making tools. Available to Microsoft 365 users with or without a Microsoft 365 Copilot license.

Fabric IQ is now generally available in Microsoft Copilot Chat and Cowork, so business questions are answered against governed Power BI semantic models, metrics, relationships and business definitions rather than ad hoc extracts. Integration with the new Code experience is coming through the Frontier program, and IQ Sharing in Fabric, which lets organizations share data plus the business context that gives it meaning while keeping governance over the underlying assets, is in preview.
Why it matters: a Copilot answer about a metric now resolves to the same definition as the official report, which removes the "which number is right" objection that stalls finance and sales adoption.
blogs.microsoft.com
Live subtitles for voice chats in Copilot will be available for users to help them follow the conversation when using the quick composer.

MC1479506 expands Video recap, the AI-generated narrated highlight video built from a recorded and transcribed meeting, to 23 languages across 31 locale variants, with regional variants for English, Chinese, French, Portuguese and Spanish. It needs a Microsoft 365 Copilot license, a meeting between 10 and 90 minutes, and cloud recording with transcription. No separate recap file is created and recap data is stored with the original recording in SharePoint or OneDrive. Rollout worldwide began late September 2026.
Why it matters: non-English teams get meeting catch-up at parity with English ones, so the Copilot license case stops being an English-first argument.
m365admin.handsontek.net
MC1479519 adds support for referencing Agents and Skills directly inside a CIQ prompt by typing / or @, with the available set discoverable from the CIQ Agents and Skills tab. The change is on by default wherever Agents and Skills are supported, needs no admin or user action, and leaves existing workflows unchanged. Rollout worldwide began mid-September 2026 and completes late September 2026.
Why it matters: it reuses the @-mention habit users already have from Teams, so agent discovery stops depending on a separate gallery visit.
m365admin.handsontek.net
We will be introducing a new Usage report covering Copilot Chat. This report will include total active users, Copilot Chat usage with a breakout per Microsoft 365 app, and user-level activity insights (anonymized by default). #copilotcontrolsystem

Roadmap item 571884 adds purpose-built legal skills to Copilot for summarizing, drafting, reviewing and redlining legal documents. The plugins run in Word and Cowork, can use work context from Microsoft 365, and can connect to supported third-party legal sources. General availability is dated October 2026 for Worldwide (Standard Multi-Tenant) on desktop, with the preview dated April 2026.
Why it matters: this is the first first-party vertical plugin set in Word, so legal teams get a Microsoft-supported redlining path instead of a third-party add-in.
microsoft.com
Roadmap item 571308 adds a Prompt Gallery of ready-to-use Copilot prompts for common file tasks, reachable from the Copilot button in the bottom-right of OneDrive, from the + button in the Copilot chat pane, and via Open Prompt Gallery. Prompts are grouped into Create, Analyze, Find and Collaborate and can be customized. Preview and general availability are both dated October 2026, Worldwide (Standard Multi-Tenant), web.
Why it matters: prompt discovery moves into the file surface where the content already sits, which is the usual gap in OneDrive Copilot adoption.
microsoft.com
MC1479505 introduces the Azure DevOps (ADO) MCP Connector, a Model Context Protocol integration between Azure DevOps and Microsoft 365 Copilot Deep Work. Agents can query and analyze work items, bugs and project data in natural language, with support for multi-step agent-driven workflows. Write actions are gated by user confirmation and configuration, and admins manage Copilot data access and the integration from the Microsoft 365 admin center. General availability worldwide begins mid-October 2026 and completes late October 2026.
Why it matters: engineering project context reaches Copilot over MCP rather than a Graph connector, which is the pattern to expect for the rest of the tool estate.

Enable Work IQ to invoke custom agents and agents that call supported third-party tools.
mc.merill.net
Expand Context IQ so users can discover and select additional agents, skills, and content sources while composing prompts.
mc.merill.net
Microsoft Viva will add a feature allowing eligible users with at least 50 Copilot licenses to export de-identified Copilot agent usage data from the Agent Dashboard for analysis. Rollout begins late May 2026 (public preview) and late October 2026 (general availability). Admins can manage or disable this feature.

Teams SDK 2.1 for TypeScript and Python adds agentic identity with lifecycle events, token acquisition and reactive and proactive messaging helpers; composability with the Microsoft 365 Agents SDK so existing Teams agents reach other channels without rewriting Teams-specific code; OpenTelemetry spans and metrics covering activity processing, handler execution, authentication and outbound Teams API calls; multi-service OAuth with connection-aware callbacks and duplicate token exchanges; built-in conversation and user state; and secure file-attachment processing including files shared by Agentic Users. Teams SDK for .NET 2.1.1 carries the Agents SDK composability and file-receive APIs and drops the Experimental attribute from targeted-message APIs.
Why it matters: observability and multi-service auth were the two gaps that forced custom plumbing in production Teams agents.
learn.microsoft.com
MC1479514 flips the tenant default for file sharing in external (federated) chats from Disabled to Enabled and applies the required permissions to shared files automatically, removing both the tenant configuration step and the manual permission assignment. Files stay in the sender's OneDrive and existing OneDrive, SharePoint and security controls continue to govern access. Admins can disable file sharing or automatic permission assignment at any time using PowerShell. Targeted Release and general availability across Worldwide, GCC, GCC High and DoD begin late October 2026 and complete late November 2026.
Why it matters: a tenant that deliberately disabled external file sharing will have it switched back on unless someone acts before late October.
m365admin.handsontek.net
Microsoft Outlook's Copilot experience will be updated in October 2026 to a simplified, chat-centered design with improved navigation, chat layout, and Work IQ controls. The full-page and side pane experiences will refresh, with no action or licensing changes required. Administrators should update user communications and documentation accordingly.
mc.merill.net
MC1479512 reorganizes Teams Events into foundational event features, available with eligible Teams licenses including Microsoft 365 Business Basic, Standard and Premium and the F1 and F3 frontline SKUs, and advanced event features, included with Teams Enterprise licenses (Office 365 E1, E3, E5 and Microsoft 365 E3, E5, E7). Teams Premium moves to legacy for Teams Events. Registration caps are 1,000 attendees on foundational and 3,000 on advanced, with 10,000 without registration on both, and capacity packs are needed beyond that. Rollout worldwide began late September 2026.
Why it matters: customers who bought Teams Premium for events now need Teams Enterprise, so any event-heavy tenant needs a license review this quarter.
m365admin.handsontek.net
Microsoft Teams' Copilot experience will be updated in October 2026 with a simplified, chat-centered design featuring improved navigation, chat layout, agent interaction, and Work IQ controls. The full-screen view adds a Tasks view. No user or admin action is needed; admins should inform users and update documentation.
mc.merill.net
MC1479517 lets users create HTML pages from + New on a site, from the floating Copilot button, or from the Publish landing page, and upload HTML authored elsewhere. Once the file is stored in the Site Pages library it renders as a page, can be edited further, published and shared, and inherits the site's existing permissions. Public preview runs in early October 2026 and general availability worldwide begins mid-November 2026, completing late December 2026. No admin action is required before rollout.
Why it matters: HTML pages land in the same Site Pages library as ASPX, so governance and retention rules written for Site Pages apply without change.
m365admin.handsontek.net
MC1479509 adds a setting in new Outlook for Windows and Outlook on the web that runs spell check automatically before an email is sent, instead of requiring a manual check per message. Targeted Release worldwide runs mid-October to late October 2026, general availability worldwide is mid-November to early December 2026, and GCC, GCC High and DoD run mid-November to mid-December 2026. No admin action is required.
Why it matters: it is a small quality control landing in the same window as the link preview retirement, so one user communication can cover both.
