It could be a glitch, if it keep giving you the error, you can log out and log back in account.

I had the very same issue!

But I just found the answer...

I had the error "problem posting your looking for group" and i could not figure out how to solve it. But as soon as Microsoft had me verify my phone number for my acount to reply to this it solved the looking for group error and it now works for me. Please
share this to any others that are having issues.

I have a problem logging in for nearly a month

I'm very disappointed with Microsoft's support team that it has not yet been able to solve the problem.
