MS Exchange Recovery

To give you a detailed answer would be too long for this forum. Located at http://www.microsoft.com/Exchange/techinfo/administration/55/BackupRestore.asp there is a Disaster recovery whitepaper for Exchange 5.5 which will walk you through step by step.

Thank You,

DO you still have the priv.ebd and all other ebd files?...
if yes,, you need to first reinstall your exchange server ( with appd service packs ) using same Organizations and sites as the previous one.

then you stop all exchange services, and replace the new ebd files with the old ones....

after that run the isingtg and eseutil tools to defrag and repair the databases..

once this is done you just need to either restart the whole server or the exchange services...

( at some point youmay need to extract or recreate all your users in the exc database )
