    Hi,

    Was looking for options to optimize our VDI environment and came across folders under X:\Users\mWazowski\AppData\Local\Microsoft\Teams which seem to have cached data. 

    Are any of the folders safe to delete from the location above and have Teams fully functional on the next user log in?

    Thanks

    Hi net_tech,

     

    If you want to clear MS Teams cache,you could refer to the following ways

    1.  Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’, or run Task Manager and fully kill the process.

    2.  Go to File Explorer, and type in %appdata%\Microsoft\teams.

     3.  Once in the directory, you’ll see a few of the following folders:

     

     a.  From within ‘Application Cache’, go to Cache and delete any of the files in the Cache location.

        *   %appdata%\Microsoft\teams\application cache\cache

     b.  From within ‘Blob_storage’, delete any files that are located in here if any.

        *   %appdata%\Microsoft\teams\blob_storage

     c.  From within ‘Cache’, delete all files.

        *   %appdata%\Microsoft\teams\Cache

     d.  From within ‘databases’, delete all files.

        *   %appdata%\Microsoft\teams\databases

     e.  From within ‘GPUCache’, delete all files.

        *   %appdata%\Microsoft\teams\GPUcache

     f.  From within ‘IndexedDB’, delete the .db file.

        *   %appdata%\Microsoft\teams\IndexedDB

     g.  From within ‘Local Storage’, delete all files.

        *   %appdata%\Microsoft\teams\Local Storage

     h.  Lastly, from within ‘tmp’, delete any file.

        *   %appdata%\Microsoft\teams\tmp

     

    Once finally done clearing, you can now restart Teams from your local desktop and all cache will be cleared from the desktop app.

    Thanks Steve!

    Just to add some clarification to my original post I would like to get some insight on what's being stored under

    AppData\Local\Microsoft\Teams & AppData\Local\Teams folders and what folder is OK to delete?

    Thank you

    This process does not appear to delete cached logon credentials.

    No.  Login credentials should be cached in Windows.  Credentials Manager

    -It's not enought to just be right.
