I received a case where 1 users is unable to receive mail in her Inbox.  New messages are received in top-level folder in her mailbox.

I configured her mailbox for my pc and the same problem resulted.  I also checked OWA and the same problem exists there as well.  I checked to see if she had any rules and there aren't any that would cause this.

Does anyone have any insight on why this is occu

Hi,

So this happens on all computers and also on OWA. Issue seems to be on the mail server side, not a Outlook client specific issue.

In this case, I would suggest you post in the dedicated forum of Exchange server, where you can get more experienced responses:

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

You could try running Outlook with the /ResetFolders command line switch.
