I, and the rest of our dev team use Linux, and found Teams ok when there was a stand-alone client for it, but the browser-based stuff they forced on us a year or so ago was horrible. The notifications were particularly atrocious, to the point of making the whole thing unusable.

The .deb of the stand-alone package disappeared, so it seemed we were stuck with the pain of the browser-based stuff. Then I remembered archive.org and found the .deb. If anyone else is in a similar situation, it's at https://web.archive.org/web/20221130115842/https://packages.... Thanks, archive.org
