The Microsoft website says that Microsoft Teams is available for Linux Here
I downloaded and installed Microsoft Teams Linux Deb 64-Bit from download page here
When I run it, and sign in I see this window:
I see this question:
Get Microsoft Teams running on Ubuntu which indicates that people are running it. What gives?
$ apt list --installed | grep teams
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
teams/now 1.3.00.5153 amd64 [installed,local]
Also, when I sign in with the same user name in Windows, all is well.
Ubuntu version 18.04.4.LTS
apt list --installed | grep teams
