PST Manager will help you understand the problems of PST files in your company. It can discover all PSTs whether they are stored on network shares or on local drives on PCs or laptops. It will tell you the owner or identify if they are unassociated and show their size. All of this will help you plan what to do with the PST and help you migrate them back to Exchange. Advance to the Enterprise version of PST Manager or to ArchiveOne to discover the content of PSTs and schedule the automatic migration of the PST back to Exchange or to an archive.
