Exchange 2010 OWA Access Denied New User accounts

All of our new user accounts within the last week are having intermittent issues with accessing it's mailbox. We have attempted deleting, both mailbox and user accounts with no luck. We have also created new users with different group policy associations, same result.

One forum suggested we should add capitol letters to the username on the OWA login screen, this surprisingly gave us intermittent results, as it would let us access the account, but only to fail about five attempts later.

We receive this error message:

"The Active Directory resource couldn't be accessed. This may be because the Active Directory object doesn't exist or the object has become corrupted, or because you don't have the correct permissions. "

If someone were to send the affected accounts an e-mail, the sender intermittently receives an "message undeliverable" e-mail, yet the affected account still receives original e-mail.

The sender receives this failure error:


Delivery has failed to these recipients or groups:

user@domain.com (user@domain.com)
The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.


Please advise.

Are you using two HUB/CAS server. If yes, can you please check the logs of IIS and Message tracking and see which server is behaving abnormally. Also confirm if you have made any changes recently or patched machines (Windows/Exchange).

     our setup is a single server environment.  IIS logs look clean.  On the updates front, Update Rollup 1 (KB2645995) was installed on 3.30.2012.  Might this be the issue?

We seem to have resolved this.  The issue was being triggered by File Replication Service errors between several of our DC's.  Event ID 13568 (journal wrap error) had occurred on 3 DC's.  Once we cleared this issue and FRS was recovered, this issues was resolved.
