Connecting and synchronizing calendars across Microsoft Teams and other services like Outlook
If Teams shows "Can't sync right now. We'll try again soon.", the supported first step is to force a refresh or restart the app.
- If a banner appears at the top of Teams, select Refresh. This restarts the app and should resync it.
- If that does not help, fully quit Teams:
- Windows: right-click the Teams icon in the taskbar and select Quit
- Mac: right-click the Teams icon in the dock and select Quit
- Reopen Teams and check whether sync resumes.
- If using Teams on mobile, open the app and pull down to refresh.
Since the cache was already cleared, the next supported action is a full app restart rather than repeating cache steps.
If the issue is specifically between Planner in Teams and the Planner web experience, that behavior can be expected in some cases. The Planner app inside Teams does not currently synchronize across platforms the same way as the web version. In that case, use Go to website from Planner in Teams to open the online version at tasks.office.com, which does synchronize with Teams.
