Vote for PST Finder
The Fortisware PST Finder is an IT-Pro tool for locating .PST files on a local network and enabling automated removal, archiving and import to Microsoft Exchange Server.
Rich reporting features make it easy to look for recently-modified PST files on the network and to monitor the status of automated imports. Determine the size of PST files on an individual and domain level for planning purposes; aggregate size data can be used to establish centralized storage needs or Exchange mailbox capacity.
PST Finder can also adjust users' Outlook settings to disable the generation of new PST files in the future on an individual workstation or domain level.
