I am running High Sierra 10.13.6
I found a fix, it seems like there is a Microsoft Teams cookie set which needs to be purged in order to allow the application to get to the Organisations SSO.
I'm certain that if I looked in Finder that I could tell you, but I've got to do some work now.
- I quit and removed the application, dropping it to Trash
- I opened a terminal, bash, and executed the following:
cd ~/Library/Application Support/Microsoft
3)
rm -r Teams -- Comment: This recursively removes the folder, don't worry, when
4)
I reinstalled the application
- Worked fine.
Bye!

So, this kept recurring, and I found a reliable way to skip over the issue.
Using a browser, authenticated to log onto the organisation, I opened outlook in a tab.
Choose Calendar, find a Teams meeting invite and click on that.
At the prompt, choose "Launch the Teams application".
Authenticates fine, 5/5 times now.
Hi,
I just delete the app, delete the folder under user/Library/Application Support/Microsoft/Teams. Empty the trash folder. Restart. Install Microsoft Teams again and Works for me.
