π’ Just shippedπ§ Microsoft 365 Copilot & AppsGA 2026-09-09
Domain Exclusion is available again after an earlier rollout was pulled, letting admins name up to 1,000 external domains that Microsoft Copilot must not use when grounding answers in public web content. It is not enabled by default and is configured with a PowerShell script rather than an admin center toggle.
Why it matters: the re-release unblocks tenants that had staged a trusted-source web grounding policy and then found the capability withdrawn

An inline chat component brings Copilot drafting into the message itself, so users do not have to open the side pane to iterate on a draft.
Why it matters: shortening the path between intent and draft is the main driver of sustained Copilot usage in mail-heavy teams

Plugins can now be found and configured from the Microsoft 365 Copilot mobile app, under the attach menu (+) > Skills.
Why it matters: plugin-backed connectors reach mobile sessions, so a task started on a phone can use the same tools as the desktop experience

The built-in App skill turns a description into a lightweight interactive app, can generate a data schema in permitted connectors, and publishes to a share link any org user licensed for Microsoft 365 Copilot can open. Rollout to Cowork ran 8 to 14 September 2026, Worldwide (Standard Multi-Tenant); apps are routed to isolated personal developer environments and surface to admins in the new Apps experience in the Microsoft 365 admin center, with a Copilot Studio equivalent following within weeks (MC1469329).
Why it matters: it needs Frontier enrolment, so it is a pilot conversation rather than a rollout, but it is the first no-code app surface that stays inside existing connector and compliance policy

Version 2.12.1 of the Microsoft.PowerApps.CLI package shipped on NuGet, which is the canonical dated release channel for pac since the tool has no Learn what's-new page.
Why it matters: pac is pinned in most Power Platform build pipelines, so a version bump is worth checking before the next ALM run

Microsoft Foundry Agent Service is now available in Azure Government, together with GPT-5.6 Sol, GPT-5.6 Terra and GPT-5.6 Luna through Microsoft Foundry. Microsoft describes the agents as usable with trusted data and tools and directed to follow organizational rules in secure mission environments; the post names no FedRAMP level, no DoD impact level and no region list.
Why it matters: sovereign-cloud parity for the agent runtime is the gate most public-sector deals wait on, though the missing authorization detail still has to be confirmed per tenant

Model router added 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 only.
Why it matters: Data Zone Standard in North Europe and Norway East is the first EU-resident routing option, which decides whether EU and Swiss customers can use model router at all

Applications can pass an opaque session ID so model router attempts the same eligible model across related conversation turns, preserving existing eligibility and fallback behavior. Responses report whether the request initialized, retained or switched the model association.
Why it matters: a router that swaps model mid-conversation is a common cause of tone and format drift in agent chat, and this is the supported fix
learn.microsoft.com
π’ Just shippedπ Microsoft FoundryPreview 2026-09-09
Clients that opt into the preview response contract receive metadata reporting the routing mode, routing-trace latency, the ordered list of model attempts, HTTP status and returned errors, which exposes when automatic fallback fired on an individual request.
Why it matters: fallback was previously invisible, so cost and latency anomalies in a routed workload could not be attributed to a specific model

Device state rules and health alerting leave the Teams admin center; health monitoring for MTR-A, phones, panels and other Teams devices moves to the Teams Rooms Pro Management portal, continuing the Android device management move communicated in MC1227622. Rollout covers Worldwide and GCC, beginning and completing in late September 2026 (MC1469551).
Why it matters: alerting rules configured in the Teams admin center stop firing, so any managed-service runbook built on them has to be rebuilt in the Pro Management portal this month

Call history consolidates missed calls and voicemails from the same contact into single entries and expands retained records from 100 to 3,000 entries or six months.
Why it matters: call history has been effectively unusable as an audit trail at 100 entries, which matters for teams running support lines on Teams Phone

π‘ Coming soonπ¬ Microsoft TeamsPlanned Oct 2026
Multi-line users get call history reorganized into a dedicated tab per line, each consolidating that line's history, voicemails and recordings.
Why it matters: delegates and shared-line users currently read one merged list, so per-line tabs remove a real source of missed calls

Users can pin content and group resources into folders beneath the chat or channel header on Teams desktop and web. Preview and general availability are both listed for October 2026.
Why it matters: channel-level pinning is the cheapest fix for the recurring complaint that shared files disappear into chat history

Admins get desk utilization analytics for Teams bookable desks in the Teams Rooms Pro Management portal; desks need an associated peripheral device for the data to be collected.
Why it matters: occupancy data is what workplace teams ask for first when justifying desk-booking rollouts, and the peripheral requirement shapes the hardware plan

FAQ creation moves to standard manual authoring inside the web part, while AI-assisted FAQ creation shifts into the Copilot in SharePoint authoring experience.
Why it matters: intranet teams that built page templates around AI-generated FAQs need to re-point that step at Copilot in SharePoint before October

The Property Sheet font size is now adjustable from Access Options, and Zoom screen-reader announcements are localized to the selected Office language.

Migration tooling for Azure-backed Whiteboards retires on 25 September 2026, after which remaining boards become read-only and can only be viewed or exported until 16 October 2026, when they are permanently deleted with no recovery; the legacy Azure Whiteboard service shuts down on 30 November 2026. Rollout covers Worldwide, GCC, GCC High and DoD from late September to mid-October 2026, and admins are told to inventory remaining boards now with the WhiteboardAdmin PowerShell module (MC1469559).
Why it matters: this is a hard data-loss deadline inside 16 days and it reaches the government clouds, so any tenant with legacy boards needs an inventory this week

Microsoft Graph now covers archive mailbox import and export plus MailboxFolder management, including auto-expanding archives, as the supported replacement for Exchange Web Services. EWS in Exchange Online begins being disabled globally in October 2026 and is expected to be fully disabled by April 2027, so eDiscovery, records management, backup and export tooling still calling EWS stops working; general availability is Worldwide from late October to early November 2026 (MC1469565).
Why it matters: the Graph replacement lands after EWS disablement has already started, so customers running EWS-based archive tooling have a gap to plan around now

Windows endpoints will classify archive files the way cloud processing already does, which Microsoft says reduces noise in event reporting and improves performance. Preview is listed for November 2026 and general availability for December 2026.
Why it matters: archive files are a standing blind spot in endpoint DLP, and matching cloud behavior removes a class of false negatives in exfiltration reporting
