There
are two kinds of files in Outlook that are used to hold all kinds of Outlook
information, OST (Offline Storage Table) file and PST (Personal Storage Table)
file. Of these two, the OST file is very helpful when the network connectivity
in your area is very poor. You can create your work and later synchronize with
the Exchange server when your connectivity is restored. However, at times the
OST file gets corrupt thereby putting all the unsaved data at risk. In such
cases, you should need an OST to PST Converter software to recover OST file by converting it as
PST.
