I have a client who recently setup a "Disaster Site" where every server from the first site gets replicated in case of a major disaster. Data can be easily synchronised (DFS), Active Directory too but what about Exchange ?
What he wants is that every mailbox has a replica on the second server, therfore in case of a crash/fire/earthquake/whatever a user can log on (using Citrix) to the other site and keep working as if nothing happened.
I can replicate Public Folders that's easy (using ExSCfg.exe) but what about the mailboxes ? Is there an Msoft tool or should I use a third-party like DoubleTake ?
