According to my research, you may try the following troubleshooting steps to see if they help resolve the issue:
- Restart your phone (power it off and then back on, rather than performing a reset)
- Clear the cache for both the Outlook and Teams apps
If the issue still persists, you must try uninstalling the Android System WebView app by following the below instructions
- Settings -> Search for "Android System WebView" -> App Details in Store -> Remove Updates
- Reboot
- Settings -> Search for "Android System WebView" -> App Details in Store -> Update
Note: If "Android System WebView" doesn't appear in the app list, go to: Settings -> Google -> All services -> System Services -> Select "Android System WebView", then:
- Reboot
- Launch Teams/Outlook & log in.
