I've installed Exchange 2007 SP1 on a Windows 2008 Data Center server x64 full server. The Server is a Dell PowerEdge 2900with 8 Gigabyte of memory and 10 Terabytes of disk space running an a RAID 5 configuration. For some reason the Information Store will not inititalize. So I've decided to un-install Exchange and do a re-install. I've saved my data store and will want to import it back into the re-install Exchange. How do I get my mailboxes/data store imported back intoExchange once the re-install is complete? Thanks
