Fix Microsoft Teams Couldn’t Load Your Calendar – Technipages

Millions of people rely on their Teams calendars to attend video meetings or keep track of the tasks they need to complete. Digital calendars and to-do lists are productivity tools of the utmost importance, yet many take them for granted. Well, people quickly realize just how important a calendar is when it stops working.

Microsoft Teams may sometimes fail to load your calendar. When that happens, the app usually displays the following message: “Couldn’t load your calendar. Let’s give it another try“. But if nothing happens after you repeatedly refresh your calendar, pursue the troubleshooting solutions below.

What to Do if Your Teams Calendar Won’t Load

Log Out and Restart Teams

First of all, sign out of your account and exit Teams completely. Then launch the app, log back in and check if you can access your calendar now. By logging out and restarting your app, you basically establish a new connection to Microsoft’s servers.

Additionally, check if you can load your calendar using the web or mobile app. Go to, log in to your account and check your calendar. A number of users were able to load their calendars by using Chrome in Private Mode.

Download the mobile app on your phone and check if you can access your calendar. Hopefully, this calendar problem doesn’t affect the web or mobile apps.

Make Sure Exchange Online is Enabled

Keep in mind that your Teams Calendar is dependent on your mailbox. Make sure your Exchange Online Plan is enabled. You can turn on your Exchange plan from the admin center.

If you don’t have permission to access the admin center, ask your IT admin to turn on Exchange Online. Check if the Calendar in Microsoft Teams works properly now.

Unjoin Device From AzureAD

If your account is managed by an organization via AzureAD, unjoin your device and restart your machine.

  1. Sign out of Office and make sure to sign in to your computer with admin rights.
  2. Then launch Command Prompt (admin rights) and run the dsregcmd /leave command. This will unjoin your computer from AzureAD.unjoin device from azureAD
  3. Restart your machine, launch Teams, and check if you can access the calendar now.

Clear Out the Cache

If the app got stuck on your old calendar data, try clearing the cache.

  1. Quit Teams and type %appdata%Microsoftteams in the Windows search bar.
  2. Delete all the files from the folders below:
    • %appdata%Microsoftteamsapplication cachecache
    • %appdata%Microsoftteamsblob_storage
    • %appdata%MicrosoftteamsCache
    • %appdata%Microsoftteamsdatabases
    • %appdata%MicrosoftteamsGPUcache
    • %appdata%MicrosoftteamsIndexedDB
    • %appdata%MicrosoftteamsLocal Storage
    • %appdata%Microsoftteamstmp.delete teams cache files
  3. Restart your computer and launch the app again. Check if the calendar problem is gone.

Should the issue persists after clearing out the cache, uninstall and reinstall your Teams desktop app.

  1. Launch the Control Panel and go to Programs.
  2. Select Uninstall a program.

  4. Then restart your computer and download Teams again.

Be Patient

Of course, if you can’t wait that long and you followed the steps above to no avail, contact Microsoft Support for further assistance or ask your IT admin to do that.
