The Top domain mail flow report in Exchange Online’s Exchange admin center will retire on July 6, 2026. After this, it will be inaccessible, requiring admins to adopt alternative reporting methods. No other mail flow reports or mail delivery behaviors are affected. Prepare by updating documentation and validating new workflows.
Outlook for iOS and iPad will add a Workweek calendar view by mid-May 2026, allowing users to focus on their workdays. iPad users can select it anytime; iPhone users in landscape mode. Users can customize days shown. No admin action is needed to enable this feature.
Microsoft will retire the noise suppression option for video playback in OneDrive and SharePoint between July and August 2026. This change affects only the playback experience; video files remain unchanged. No admin action is required, though updating documentation and notifying helpdesk is recommended.
Chat history in the Copilot navigation pane will be filtered by the current Copilot experience, with an option to view all chats. This change, rolling out April-May 2026, affects all Microsoft 365 users, requires no admin action, and does not impact data storage or compliance.
Microsoft Teams will introduce two new chat sections—Muted chats (enabled by default) and Meeting chats (disabled by default)—to organize chats. These sections group muted and meeting chats separately, can be toggled by users, and will roll out globally from early to mid-May 2026. No admin action is required.
Undo and Redo support for PDF annotations in OneDrive and SharePoint on the web will roll out worldwide in April 2026. Users can undo/redo ink, highlights, and text via keyboard shortcuts or toolbar buttons. The feature is enabled by default, requires no admin action, and improves annotation editing.
Starting May 2026, files deleted from OneDrive cloud won’t appear in local Recycle Bin or Trash but can be recovered from the OneDrive or SharePoint web recycle bin. Local deletes remain unchanged. No admin action needed; users should be informed about the new recovery process.
Starting May 4, 2026, Anthropic models will be enabled by default for Copilot in Word, Excel, and PowerPoint, with data processing outside the EU Data Boundary. Admins can review or change this setting anytime in the Microsoft 365 Admin Center. Word support begins summer 2026.
Starting April 17, 2026, Microsoft enables flex routing for EU and EFTA tenants using Copilot, allowing LLM inferencing outside the EU Data Boundary during peak demand. Data remains encrypted, with limited pseudonymized data stored outside. Flex routing is on by default but can be managed in the Microsoft 365 admin center.
