Updated November 25, 2025: After further review, we will not be rolling this out to GCC, GCCH, DoD, USSec, USNat during the timeline outlined below. We will communicate via Message center in dedicated posts when we are ready to proceed. Thank you for your patience.
We’re introducing the new Microsoft Teams calendar experience, designed to unify and enhance productivity across Microsoft 365. This calendar integrates familiar features with innovations like Microsoft Copilot and Microsoft Places, enabling seamless collaboration from anywhere. It works consistently across Teams, the new Outlook for Windows, Outlook on the web, and Places. As part of this update, the legacy calendar experience will be deprecated, and the toggle to switch between old and new calendars will be removed.
When this will happen
- General Availability (Worldwide): Early November 2025 – Mid-November 2025
Once this update is deployed, users accessing the Calendar app in Microsoft Teams will see the new calendar experience by default. The toggle to switch between the old and new calendar will be removed, and only the new Microsoft 365 calendar will be available. This change may impact users accustomed to the legacy calendar interface.
What you can do to prepare
No admin action is required. We recommend informing your users about the upcoming change and updating any internal documentation or training materials that reference the legacy calendar experience.

Compliance considerations
No compliance considerations identified, review as appropriate for your organization.
