November 2025 Teams Calendar Updated and now missing events on the calendar

If you are experiencing missing events on the Teams Calendar after the November 2025 update, it could be due to several reasons, including synchronization issues or changes in how events are displayed following the update. Here are some steps you can take to troubleshoot the issue:

1. Check Sync Settings: Ensure that your calendar is syncing correctly with Microsoft Teams. Sometimes, a sync issue can cause events to not appear.
2. Recreate ActiveSync Relationship: If you are using a mobile device, consider removing and then re-adding the ActiveSync relationship to refresh the connection.
3. Review Event Filters: Make sure that any filters applied to your calendar are not hiding certain events.
4. Check for Updates: Ensure that your Teams app is updated to the latest version, as updates can fix bugs related to calendar functionality.
5. Contact Support: If the issue persists, consider reaching out to Microsoft support for further assistance.

These steps should help you identify the cause of the missing events and restore your calendar functionality.

How do I do all of those steps?

Hi @Carissa Della-Pietra, 

Thank you for posting your question to the Microsoft Q&A forum. 

I understand how important it is to be able to view events in your daily workflow.  

Based on your description, I would recommend trying these steps:  

1. Clear Teams cache  a. On MacOS: 

• If Teams is still running, right-click the Teams icon in the dock, and then select Quit or press Command (⌘)-Q. 
• In the Finder, open the /Applications/Utilities folder, and then double-click Terminal. 
• Enter the following commands, and press Return after each command: 
  • rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams 
  • rm -rf ~/Library/Containers/com.microsoft.teams2 
  b. On  Windows: 
• If Teams is still running, right-click the Teams icon on the taskbar, and then select Quit. 
• Open the Run dialog box by pressing the Windows logo key +R. 
• In the Run dialog box, enter the following path, and then select OK. 

%userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams 

• Delete all files and folders in the directory. 
• Restart Teams. 

2. Sign out and sign in again 

In Teams, sign out of your Microsoft account and sign back in. 

3. Contact Microsoft Support 

If the issue still persists after trying the above steps, please use your organization's administrator account or contacting your IT administrator. They can submit a support request through the Microsoft 365 Admin Center for further assistance.
