@asfrdns777 Does the user actually have a mailbox? If yes, are there any cached credentials that could change the the Mailbox you try to login to. 

Is the User activated and has the permission to access OWA? 

Set-CASMailbox -Identity <User> -OWAEnabled:$true


Are there any typos in AD Advanced Attributes for Exchange properties that could affect the mailbox configuration/access?

@AlexHoehn Hi,


Thanks for the replay.

This is my user: administrator.  and owa is enabled.


Was the user migrated to a new Exchange Server? Was the Mailbox maybe disabled/disconnected in some point of time? There seams to be a mismatch between userobject and exchange mailbox.
