We’re pleased to announce the Teams client for Linux is now available for preview. Please see details at https://techcommunity.microsoft.com/t5/Microsoft-Teams-Blog/Microsoft-Teams-is-now-available-on-Linux/ba-p/1056267.
Please check out the Q&A forum here – https://docs.microsoft.com/answers/topics/teams.html.
This is rather disappointing with how vested our company is within the Microsoft/Office365/Azure architecture. Tough blow to the users using Linux, we've been waiting for better support to make the full swap from legacy communication methods to Teams, however this makes the decision much easier for other methods.
If a Linux client is to not be made, can we at least get better native browser notification support? Our users constantly miss messages in our initial testing of Teams.
This is still being worked upon and making good progress! Stay tuned for additional updates.
