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.

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:
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.
Please fix this, it's ridiculous that this is required.
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.

Why authorize third parties cookies and for what domains, I can't see any doc on that

three years later and this is still a problem
For Chrome allow this site in regards to cookies:
....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.
this seems to be very old issue that hasnt been resolved yet. I am surprised this isnt addressed till now. I wish they address it with priority
As per usual: Function first, add security only AFTER someone is hacked because of it.
I would like to add my voice to this.
The service should not rely on Third Party cookies to function.
We have sites that cannot use teams web application because of the 3rd parth cookies and their firewalls have blocked access. Please remove all third party cookies from the tool.
100% BS requiring dumbing down security measures to allow use. Will keep our dept clear of this nonsense.
Can I just say I have been allowing 3rd party cookies for 25 years and never had a problem with them. You get warned when the browser knows a site is no good so you can cancel prior to actually being on it.
I am all over the internet every day at least 6 hours a day with work and personal. Thinking may be thing of the past.
I think you would need cookies with O365 sites in order for necessary operations between your client and the Server.
I am not an MVP just a business owner so take this with a grain of salt, I am just giving an opinion based on my usage.
Wishing everyone a properous new year!!

Has similar error on fresh Windows 10 installation. Tried to open Microsoft Teams in Chrome. received error message "D'oh! To open the web app, you need to change your browser settings to allow third-party cookies."...
Added teams.microsoft.com as trusted site on Ghostery which solved the issue.
