Outlook showing fqdn instead of email adresse

[Daguerre101]

Good day,

I have a user that instead of seeing email adress, sees complete FQDN of the users she wants to send email to: (see image)

Do you know what could cause this? She seems to be the only one so far.

Thanks

@Daguerre101  - I am seeing the same issue. Did you ever find a resolution?

@TeriH560  No it simply stopped by itself. One day that was there and the other day it was gone. To my knowledge I did nothing that could have solved this situation.
