In order to work around the Exchange storage limits, my users have taken to creating multiple PST files to archive their mail. Each PST can be between 500MB and 1.5GB in size and each user has 3 or more PSTs active at one time.
I would like to keep a copy of these PSTs to the file server for backup purposes, but have been unable to find a way to get them up to the server. We have tried using Offline Folders in Windows XP, but it does not support PSTs. We have tried using SyncToy, but it copies the entire file as a whole and my users don't have the patience to wait for 4GBs to replicate across the network.
All the third-party software that I found only support 1 PST at a time.
Does anyone have any suggestions?
