We’ve released updates to the following update channel for Microsoft 365 Apps:

Microsoft Teams will remove the toggle for the legacy calendar, making the new integrated Microsoft 365 calendar the default. This update rolls out from September to December 2025 across various environments. No admin action is needed, but users should be informed and documentation updated accordingly.

The Rewrite Suggestions feature in Microsoft Word will be deprecated after October 1, 2025, and replaced by the more advanced Copilot experience, offering context-aware rewriting, prompt-based editing, and iterative refinement. Users are encouraged to transition to Copilot’s Auto-Rewrite for enhanced writing assistance.

Microsoft To Do will stop supporting iOS 16 and macOS 12 starting late August to mid-September 2025. Updates will require iOS 17 or macOS 13 and later. Users on older versions won’t receive updates, potentially affecting app performance and security. Organizations should encourage OS upgrades and update device policies.

Outlook for Windows will introduce a new Account Manager in August 2025, showing profile pictures, enabling account switching, and providing quick access to account details. This feature is on by default, requires no admin action, and aligns with classic Outlook to enhance productivity.

Outlook and Teams will get a refreshed Event scheduling interface with new Copilot features to enhance meeting creation. Rolling out from mid-August to mid-November 2025, it will be enabled by default without admin action. Prepare by informing users, providing training, and updating documentation. No compliance issues noted.
