MS doesnt support the use of pst's over a network as it can, and apparently
has led to corruption of the data files.
Copy your Archive to the local HD, make a copy on the local hd, then try
running scanpst.exe on that copy.
If scanpst cannot repair it, then you are left with trying paid for recovery
utilities

I set up Outlook to archive folders to a Network drive.
On one occasion the Network drive was not available and now I cannot
access
any of my archive emails

How do I recover?
