🧠 Microsoft 365 Copilot & Apps

🟢 Just shippedGA 2026-09-11

Session and Response Sharing in Microsoft 365 Copilot

Copilot users can share a full chat session or a single response through a link. The shared content opens as a read-only view and recipients can continue from it in their own Copilot chat. Rolling out worldwide (Standard Multi-Tenant) across web, desktop, Mac, Android and Teams/Surface devices.

Why it matters: Replaces copy-paste sharing of Copilot output, keeping reuse inside tenant sharing controls instead of loose email threads.

Suggested artifact creation in Copilot Notebooks

Copilot Notebooks in OneNote now suggests artifacts to create - Word documents, Excel workbooks, PowerPoint presentations - based on Microsoft 365 knowledge and the content of the notebook, and generates the artifact when the suggestion is selected. Rolling out worldwide on desktop and web.

Why it matters: Turns Notebooks from a grounding surface into an output surface, shortening the path from gathered research to a client deliverable.

Co-authoring highlight and rewrite in Outlook

Users select a section of an email draft and ask Copilot to change its length, tone or structure, rather than regenerating the whole draft. Launched worldwide (Standard Multi-Tenant) on Outlook web.

Why it matters: Section-level rewriting is the control most drafting complaints ask for, and it arrives without a new license.

Admin control for Learning Activities and Teach withdrawn

The roadmap item that would have let admins manage access to Learning Activities and Teach from the Microsoft 365 admin center, configured separately for educators and for students aged 13 and older, has been cancelled and removed from the public roadmap as no longer accurate. Worldwide (Standard Multi-Tenant).

Why it matters: Education tenants staging a rollout of these AI experiences lose the promised admin gate and need another readiness control.

Edit with Copilot in Excel reaches Office 365 GCC

Edit with Copilot lets users build and edit workbooks side by side with Copilot, using tables, charts, PivotTables and formulas. Listed for GCC, GCC High and DoD on web, Win32 and Mac.

Why it matters: Government-cloud tenants get the Excel editing surface commercial tenants already have, which matters for public-sector bids.

🟡 Coming soonPlanned Oct 2026

Copilot edit mode in Word reaches Office 365 GCC

Edit with Copilot in Word becomes available to Office 365 GCC users, letting government customers work with Copilot as a co-creator directly in the document. Listed for GCC, GCC High and DoD on web.

Why it matters: The same sovereign-cloud gap closing in Word; check each customer's cloud instance before promising availability.

Copilot Analytics adds Cowork adoption and impact insights

Cowork adoption and impact metrics are now available from the new AI Cost dashboard and the Copilot dashboard, with export. Analysts can query all metrics through the new AI cost query in advanced insights. Launched worldwide (Standard Multi-Tenant) on web.

🛠️ SDKs & Dev Tooling

🟢 Just shippedGA 2026-09-11

Microsoft Agent Framework .NET 1.21.0

The release adds workflow output in hosted agent responses, Foundry hosted session client support, A2A task state transition tracking and subprocess environment isolation for LocalCodeAct. Breaking changes: MCP skill archives are restricted to ZIP only, line-numbering contracts consolidate into AgentFileStore, and the Azure.AI.OpenAI dependency is removed.

Why it matters: The ZIP-only skill archive and the AgentFileStore consolidation will break existing custom agent builds, so pin the version before upgrading.

💬 Microsoft Teams

🟡 Coming soonPlanned Nov 2026

Separate attendance and engagement report policy for Teams events

Teams events get an attendance and engagement report policy separate from CsTeamsMeetingPolicy, so admins can let event organizers reach these reports while restricting access to Teams meeting attendance reports. Listed for Worldwide (Standard Multi-Tenant) and GCC on desktop.

Why it matters: Lets events and marketing teams keep their reporting without loosening meeting-level attendance data for the whole tenant.

📁 SharePoint & OneDrive

🟢 Just shippedGA 2026-09-11

Document library views come to OneDrive

Users can work with SharePoint document library views directly from OneDrive, switching between existing views and creating and managing new ones. Launched for Targeted Release and Worldwide (Standard Multi-Tenant) on web.

🟢 Just shippedGA 2026-09-11

Refreshed Libraries view in OneDrive web

The More places experience in OneDrive web is replaced by a refreshed Libraries view showing more recently accessed libraries, default document libraries for Teams and favorite SharePoint sites, plus new filtering, sorting and view options. Launched for Targeted Release and Worldwide on web.

Why it matters: This changes a navigation surface end users know by muscle memory, so it is worth a line in tenant comms before it lands.

📧 Outlook & Exchange

🟢 Just shippedGA 2026-09-11

Respond to meeting invitations from the message list context menu

Outlook for Windows (new) adds meeting invitation responses to the right-click menu in the message list, so invitations can be answered without opening them. The page notes Outlook for Windows (new) is still not available in Azure Government.

Why it matters: Small friction removal on a daily action, and the Azure Government gap still needs flagging for public-sector tenants.

🟢 Just shippedGA 2026-09-11

Folder pane section added to Mail settings

Mail settings in Outlook for Windows (new) now include a dedicated Folder pane section, consolidating the folder pane options that were previously spread across the settings surface.

🟢 Just shippedGA 2026-09-11

Bulk edit and delete categories in People

The People hub in Outlook for Windows (new) now supports editing or deleting several categories at once instead of one at a time.

Why it matters: Makes category clean-up practical after a migration, where contacts typically arrive with dozens of stale categories.

🟡 Coming soonPlanned Oct 2026

Customize the classic ribbon

Users will be able to right-click the classic ribbon and choose which commands and groups appear on the Home and View tabs. Worldwide (Standard Multi-Tenant) on web.

Why it matters: Ribbon customization is a recurring ask from users moved off classic Outlook, and it reduces the retraining argument against migration.

📝 Office Apps

🟡 Coming soonPlanned Sep 2026

Cascading combo and list boxes in Access

Combo boxes and list boxes gain LinkMasterFields and LinkChildFields support, enabling cascading dropdowns - a Country field filtering a City field - without writing VBA. Preview landed July 2026; GA listed for September 2026, worldwide on desktop.

Why it matters: Removes VBA from a very common Access form pattern, lowering the maintenance burden on legacy departmental databases.

⚙️ M365 Admin & Compliance

🟢 Just shippedGA 2026-09-11

Endpoint DLP extends to Copilot+ PC Recall snapshots

Purview Endpoint DLP expands coverage to Copilot+ PCs, so custom policies decide whether capture of windows containing restricted sensitivity labels or sensitive information types is prevented in Recall. Purview admins author the Endpoint DLP custom policies; Intune admins set up Recall on the devices. Rolling out to GCC, GCC High and DoD.

Why it matters: Recall has been the hardest Copilot+ PC objection to answer for regulated customers, and this is the first DLP-grade control over it.

🟡 Coming soonPlanned Oct 2026

Sensitivity labels visible on MIP-protected PDFs in Edge

The new PDF viewer in Microsoft Edge will show sensitivity labels applied to MIP-protected PDFs, so enterprise users can see the data classification before handling the document. Worldwide (Standard Multi-Tenant).

Why it matters: Label visibility at the point of reading closes a gap where protected PDFs looked identical to unprotected ones.
