Folders Missing from Inbox in OWA 2003

Specs: Front-end Server
 - SBS 2003 R2 running Exchange and OWA;
 - Using Backup Exec 11d with updates applied

History: Recent failures of backup jobs due to "inconsistencies" in the Exchange mail store prompted me to run a hard repair on the store, defrag with eseutil, and check with isinteg (this past weekend).  This has been an ongoing problem and the hard repair had come down to being the only solution.  All went well, though, and isinteg reported 0 errors on the second run.  Everything came back up with no problem, except that one user doesn't have any of the folders she created in her Inbox anymore, and all her old messages are gone.

Oddly, she reported the missing folders to me on Friday, prior to the hard repair.  But with no recent successful backups because of the inconsistencies, I was not able to restore her mailbox at that time.  She also just started using a new desktop that has Outlook set up for POP access, but I checked the pst file there and it's empty also.  Prior to using the desktop, she had been accessing her e-mail solely through OWA, so all her folders and messages should have been on the server.  

I have tried clearing the Temp Internet Files on her machine, hoping it was simply a caching issue, but no luck.  Any ideas as to where her folders and messages went, and if there is any way to get them back, would be most appreciated.  I'm not holding out much hope at this time, but thought I'd give EE a shot just in case someone knows a nifty trick I'm overlooking.

Thanks,
