Tiny remark.. depending on wich teams version you are using it might alternatively be called "teams-insiders". Thx!

teams-insiders I have not tested. Is it change process name, @leflamm ?

@mrcomoraes, yes, the process name is different ("teams-insiders"), the directory names are still the same. Cheers!

Thank you!

@mrcomoraes A comment on what's stored in the various cache directories may be useful, e.g.

rm -rf Local\ Storage/* # Password screen cached here

@mrcomoraes - check out my fork, I've added support for the Insiders build of MS Teams via DEB install. There's a snap for that too, but I don't use it and haven't accounted for it in my revisions.

Why do we need to run teams before using this script? Cache clearing should work even if teams isn't running. BTW awesome work 👍

@armujahid
In past, when I run clear cache script with MS Teams closed, it's removed auth and names of the chats, staying only IDs instead names.
So I read some MS Teams on Windows forums and they run clear cache scripts for Windows with Teams running.

Perfect, thank you! 👍
It improved the search performance. Waiting to see if it also fixes the unexpected crashes during calls and screen shares.

Thanks, I was trying to signout from my inactive work account. Even after reinstalling teams i landed up in same old signin page. This script helped me to clear cache and switch to new account in Linux.

Thanks for the script. I was having issues after upgrading to Ubuntu 21.04 (from 20.04).
Just adding some notes for others -- in case they see the issues similar to mine.
The app would load but never showing any chat messages.
I ran this script multiple times and saw the files were deleted, however, it never would show the messages.
finally, I ran the script and cleared everything and uninstalled and re-installed Teams and it finally worked.

Works like a charm! But in my case directory is very different:

$HOME/.var/app/com.microsoft.Teams/config/Microsoft/Microsoft\ Teams

OS: Manjaro, Teams installed through flatpak.

@danie1k I have not tested on flatpak Teams package. I will update script with flatpak support.
