Thanks for your useful shell script! It's very helpful for me to reset my teams settings!

Thanks, the script is easy and fantastic

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/\ Teams

OS: Manjaro, Teams installed through flatpak.

Copy link

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

Copy link

Hmm... weird, when i fun it in bash i get the following error....

fremling@Sill:~$ ./ deb-stable
./ line 31: syntax error near unexpected token )' ./ line 31: *)'

Copy link

mrcomoraes commented Sep 19, 2022

@fremling I have fix a block code that causes errors.

Please, update script and run again.

Copy link

Any reasons why the process needs to be running?
I am thinking that maybe someone wants to clear the cache without Teams running.

Copy link

In last test, when Teams aren't running and start clean cache, some data of authentication is cleared too.

Currently I'm not tested. Feel free to validate.

Copy link

My snap installation has following location - $HOME/snap/teams-for-linux/current/.config/teams-for-linux/

Copy link

My Ubuntu 23 snap installation Cache has following location $HOME/snap/teams-for-linux/current/.config/teams-for-linux/Partitions/teams-4-linux/ and the process to be killed is named teams-for-linux

Copy link

@MarekGajdosik and @maksimdzmitryew this "Teams for Linux" snap is a unofficial project that using Electron for deliver MS Teams. I beleive Microsoft removed Teams snap packages. I guess do a upgrade in snap option to support unofficial version.

Here is my first time on GitHub.
However, here is my contribution to this topic.
I have Ubuntu as my SO, and my teams-for-Linux is a fork on the Snap.

I changed lines 24, 25, and 26 to:

export TEAMS_PROCESS_NAME=teams-for-linux
cd /snap/teams-for-linux || exit 1

run ps to find your teams-for-linux process and you will see that:

$ ps -ef |grep teams-for-linux
me 324126 323853 0 12:32 ? 00:00:00 /snap/teams-for-linux/523/teams-for-linux --type=utility --utility-sub

So my teams-for-linux is on directory /snap/teams-for-linux
and the TEAMS_PROCESS_NAME is teams-for-linux and not just teams
