A user has just reported to me that all of their data is missing from their Outllok archive folder. She had many folders full of emails in her archive, but they all disappeared today. I had a look and found that the archive.pst file containd only sent items and no other folders. I have run scanpst on the archive file and it found no issues. The archive file is stored on the local PC, and we only backup the server (SBS2003 server with exchange). I'm at a loss as to what has happened. Can anyone suggest what may have happened, and more importantly is there anyway to get the data back?
