So we've had some trouble with the MFA lately. The first time I enabled/enforced MFA for my organisation Microsoft had the longest outage for MFA making it impossible to login with MFA for a couple of days. Which wasn't a good start for us if you ask me.
When this was fixed I waited a while to enable it again. I started gradually this time and it worked fine.
But after a while some users noticed that when they are trying to configure their email account on a new computer or phone they just get an error saying something went wrong.
I have my mail configured on my work computer with the app password I created when I got asked to login again after MFA had been enabled and that worked just fine.
I had to login to my phone as well and that's where the problem started. I created a new app password for my phone but no matter what I do I can't get my phone to accept either my actual password or the app password. I've tried with multiple app passwords without success.
If I try to add my account on my home computer I just get this:
If I disable MFA for my account it will work perfectly however. So there is something wrong with MFA and I don't know how to troubleshoot it.
Everyone that I've enabled MFA for has the same problem.
What can I do to fix this?
