Scanpst.exe is a utility used to fix MS Outlook PST files. Scanpst can partially fix internal PST file database issues, but in most cases you should try a third party Scanpst.exe tool.
It is possible to split PST mailboxes into different files located locally or on a network driver. The problem is that while a network driver can appear as a local drive (drive mapping), the network drive does not have the same performance as a local drive (i.e. a C drive). Therefore, Outlook may experience problems contacting the PST file on the network server which may sooner or later lead to a corrupt PST file which needs to be repaired with scanpst.exe
If such an error occurs, it is possible to first restore your PST file mailbox with backup software that is daily backup in your network storage. However, since the mailbox data can contain crucial business data, you may not even want to lose a single working day.
If restoring the mailbox data in your inaccessible PST file is a must try the Scanpst.exe utility. The Scanpst.exe location is in your Outlook installation folder (you may find it under the default installation folder, which is c: program files). If you cannot find it, it is best to just run the search tool and find the scanpst.exe directly.
Typical PST errors:
“The file F: archive.pst is not a personal folder file.”
(you can replace the letter F with your own network drive letter).
Cause for the PST error:
The above error indicates that Outlook cannot read the PST database because it is corrupt. The file does not have a valid database structure. Another possible cause is that you just don’t have a network connection with the PST file. In that case, it is very easy to fix and just call your network administrator to fix it.
Note that the Outlook PST database file is not designed to work with slow connections such as network drives. In many cases, the connection slows down while saving data or closing files, in many cases causing data loss and PST file corruption.
