To open the web app change your browser settings to allow third-party cookies or allow certain trusted domains

This was interesting to figure out, but I did finally figure it out. Thought if you’re Googling this, you’d want to know too!

I got this error when I was logging into Teams online using Chrome. I tried it in regular and incoginito mode. Both failed.

Then I had to think of why I’m getting the error when I’m logging in with the correct username and password, it dawned on me that lately I’ve been noticing Chrome get angrier with any 365 logins. I went to Edge and opened “InPrivate Window” and sure enough, worked great. This also solved another issue I was having with adding Teams members to Teams oddly enough.

I hope this helps you down your journey of troubleshooting.
