Hi guys, we are experiencing the issue in the title lately from a number of machines.
When we try to authenticate on O365 or Dynamics, the redirection to the login page takes up to 20 mins.
Here is what's happening: when we try to open the page https://portal.office.com we are correctly redirected to login.microsoftonline.com to perform the authentication process. BEFORE we can see the page where to insert the upn apparently the system loops for up to 20 minutes. And after inserted the credential we have another loop for another 10-15 minutes.
After the process complete successfully then the following logins are "normal".
So you know a way to debug that process? We used wireshark (there we can see the connection re-trasmitted but nothing else significant, tried to remove the cookies, reset the browser settings, clear the cache, etc..)
Any suggestion is welcome.
Thank you

I wanted to check if this is happening for all users of any specific users?
Is the issue happening only on one device or all devices?
Since when you are seeing this issue?
Was there any change in your environment after which the issue might have started?

2024-03-19T12:12:51.8433333+00:00 Thank you for your answer. The issue is happening on a subset of user let's say 50 in a pretty specific environment (a sub company).Apparently the only operation that could match the timeline and we are aware of is a GPO that removed the users from the local "Administrators" group (even if the users weren't in that group).
The last test we did was to recreate the user profile from scratch and on a win11 machine apparently it worked, while in a win 10 it didn't.
I don't know if it is related of not but also when logging on the first time the process takes forever before user can access the machine.
