M365 Entra ID Guest cannot set up mfa

Question

Hi there,for a week now, Entra ID guests from Our M365 tenant have not been able to set up the Microsoft Authenticator app. Error message: "Unfortunately, an error occurred" after the number was confirmed in the app.&nbsp;We are sure that the problem is not in our tenant settings - but also dont find informations about a microsoft issue.Microsoft ticket opened. But Microsoft has been silent for a few days.&nbsp;Any ideas?&nbsp;&nbsp;

You should focus Microsoft Support on this

No, my money is on something on MS side. But to get to the bottom of it, you will need a support case first.
