Acknowledge exceptions for third party cookies instead of demanding a huge security hole!
I tried Chrome, IE 11, and Edge (don't get me started on the Edge issues!) and all required that third party cookies be fully enabled. It would not acknowledge an exception for all teams.microsoft.com addresses.
IE 11 is riddled with script errors and it prevents the download of the desktop app.

Ridiculous, unprofessional and quite frankly it's embarrassing. None of the other portals require third-party cookies.

Why hasn't this been fixed yet? Are there no developers at Microsoft anymore?

Why are you requiring third party cookies for the ADMIN page.

WTF Microsoft!? Even to use the admin page?!?!?! Come on man, this is ridiculous.
How do large corporates use this system? Unbelievable

My company wants to move from Slack to Teams. First the usability problem that neither the invitation nor the login form said you first need a Microsoft account associated to the email address. Then the website asked for permission to run a binary on my (Linux) computer. And now this third-party cookie nonsense.
Based on this experience, I will try to veto the move.

You need to fix this. Google Chat i G Suite do not require this. As for now, I can't use Teams for my virtual teams at work since my employer do not allow third party cookies. I'm in the information security business so they will never allow that.

I voted for this, though I was able to get Teams to load in the "new" Edge (v. 81) by adding exceptions at Settings > Site Permissions > Cookies and site data > Allow, for:
teams.microsoft.com
[*.]microsoftonline.com
[*.]office.net -

Took me quite a while to understand what's going on because I was just being forwarded all the time and ended up at "To open the web app, you need to change your browser settings to allow third-party cookies." eventually. Why do you need third-party cookies?! I refuse to active them.

The need for third party cookies at "TEAMS" is a NO GO!

Really Microsoft? It's a global pandemic and your product "teams" is needed. Why do you make it so incredibly hard? I cannot allow all 3rd party cookies just to download your software. Sticking with Slack. Thanks and no thanks. P,S. You also make me jump through hoops just to post a comment. Feeling annoyed.

For Chrome allow this site in regards to cookies:
[*.]microsoftonline.com -
BW commented
....at least tell us which 3.part cookies you are using so we can open up for those.
Enable 3rd part cookies in general is insane!

Yes. A simple admin page absolutely should not require third party cookies.

Entire US Govt agencies are unable to use MS Teams. 3rd party cookies disabled by policy for the enterprise. I can't believe that 3rd party cookies are required and there is no alternate solution for the web. The desktop client isn't installed or available to us yet.

As per usual: Function first, add security only AFTER someone is hacked because of it.
