Clear the Teams Cache

Sometimes the installed Microsoft Teams app can get itself in a muddle, and the easiest way to rectify it is to clear the app of any locally stored information and sync from the cloud from scratch.

This is a simple process, though feel free to ask IT support for assistance.

These instructions are a shameless copy and paste from this Microsoft article and this blog post too

Windows

iPhone or iPad

macOS

Clear Teams cache on iPhone or iPad

Apple makes clearing the cache on their mobile devices a bit more difficult. To clear Teams’ cache on your iPhone or iPad, you’ll need to either offload or uninstall the app.

Offloading an app will erase all of its temporary data, like the cache, but keeps the app’s icon and most vital data on your device. Uninstalling it erases all of its data, including its icon.

1. Open the Settings app and tap General, and then either iPhone Storage or iPad Storage.
2. Wait a few moments for a list of all your apps to load, then scroll down and select Teams from the list.
3. Choose whether you want to Offload or Delete the app.

3. Enter the following command, and then press Return:

   rm -r ~/Library/Application\ Support/Microsoft/Teams
   

4. Restart Teams.

3. Select the Clear cache option.
