Microsoft Teams and Google Calendar sync retirement

🚨 The Signal: Microsoft is retiring direct calendar synchronization between Teams and Google Workspace in October 2026. This removes a native integration, requiring organizations to use alternative methods for cross-platform scheduling, potentially impacting operational efficiency and data flow.

The Impact

Organizations using Teams-Google Calendar sync are affected, with a low security risk as it removes a data integration point.

• Admins: Must notify users and retrieve sync data before October 2026.
• Users: Will lose automatic calendar sync, potentially causing scheduling errors.
• Security Teams: Review data flow policies for cross-platform scheduling.
• Compliance Teams: Assess impact on data residency and integration policies.

The Action

1. Identify users currently relying on Teams-Google Calendar sync.
2. Communicate the retirement of calendar synchronization to affected users.
3. Retrieve and retain any necessary account matching information from the Teams Admin app.
4. Evaluate the Microsoft Teams Meeting add-on for Google Workspace as an alternative.
5. Update internal documentation and user guides regarding cross-platform scheduling.
