Scanpst.exe is a utility accustomed to correct MS Outlook PST files. Scanpst can partially fix internal PST file database issues but in many instances you will have to try a 3rd party Scanpst.exe tool.
It's possible to split PST mailboxes into different files located locally or over a network driver. The problem is that although a network driver may seem like a local drive (drive mapping) network drive not provides the same performance as a local one (i.e. C drive). Therefore Outlook may face problems to make contact with the PST file situated on the network server understanding that usually leads ultimately to corrupt PST file which need a repair with scanpst.exe
If such a failure happens, it is possible to reinstate your PST file mailbox first with backup software that's daily backup in your network storage. However, since the mailbox data could have some crucial business data you could don't want to lose a day of work.

Scanpst.exe location is at your Outlook installation folder (It may seem underneath the default installation folder i.e. c:\program files). If you cannot think it is the most effective is merely to run the search program and discover the scanpst.exe directly.
Typical PST errors:
"The file F:\archive.pst is not a personal folders file."
(you are able to replace the letter F with your own network drive letter).
