Microsoft Teams won't connect no matter what I try

Introducción

If Microsoft Teams is not working after many attempts, this guide shows you what you can try using file explorer.

In the search bar enter "Run" and type in %appdata%\Microsoft\teams
From ‘Application Cache’, go to Cache and delete any of the files in the Cache location. “%appdata%\Microsoft\teams\application cache\cache”
From ‘Blob_storage’, delete any files that are located in here if any. “%appdata%\Microsoft\teams\blob_storage”
Within ‘Cache’, delete all files “%appdata%\Microsoft\teams\Cache”
Within ‘databases’, delete all files “%appdata%\Microsoft\teams\databases”
Within ‘GPUCache’, delete all files “%appdata%\Microsoft\teams\GPUcache”
Within ‘IndexedDB’, delete the .db file “%appdata%\Microsoft\teams\IndexedDB”
Within ‘Local Storage’, delete all files “%appdata%\Microsoft\teams\Local Storage

Lastly, from ‘tmp’, delete any file “%appdata%\Microsoft\teams\tmp”
Once finally done clearing, you can now restart Teams from your local desktop and check if the issue disappears.
