I just did this last week and it was quite a project. If you are setting up Exchange on a backup server you need to make sure that the new server is off the network and it must be it's own DC in a new forest. Set the organization name the same as your production server. Actually, I made everything the same just to be safe (Including the server name). I use Backup Exec and after many tries it finally works the way I want it to. After you restore the Information store, create a user in AD and connect it to the mailbox that you want to restore. I installed Outlook on the backup server for single mailbox recovery. Now I can export all the mail from the mailbox to a PST and import it back into my production server. I hope this helps! -----Original Message----- From: Lacaille, Michael [mailto:MLacaille@xxxxxxxx] Sent: Tuesday, February 05, 2002 11:08 AM To: [ExchangeList] Subject: [exchangelist] RE: Help Please!!!! http://www.MSExchange.org/ I have not done this, but we have just recently helped another Exchange administrator on site implement Tivoli back up for our server. From what I understand about restoring the IS, is that it would need to be put on a server that is identical to the existing server. I hope that someone else who has more experience, can assist you with this issue. Good luck! -----Original Message----- From: Muqeem Syed [mailto:Syed.Muqeem@xxxxxxxxxxxx] Sent: Tuesday, February 05, 2002 11:39 AM To: [ExchangeList] Subject: [exchangelist] RE: Help Please!!!!
