Our server is Windows 2003 SBS SP2 + Exchange 2003 SP2
One of the user mailbox is 15gb and disconnected. He has download all email in Outlook 2003 before. (OST and PST)
Because the user connected to new mailbox now. We would like to backup the old one and then purge it from Exchange to reduce the size of mail database.
Because we planning to do Backup per week but the database too large.
According to other post, ExMerge can export .pst file but the file size will be double.
Except ExMerge, how to move out that 15gb Mailbox from Exchange database and it can be restored if need?
