tim2008 Posted July 30, 2010 Report Share Posted July 30, 2010 hello, we've got Retrospect Multi Server Version 7.7.325 (32 Bit) Driver-Update and Hot Fix Version 7.7.3.102. Retrspect is running on a Dell Server R300, MS Windows Server 2003 RE SP2. We do for years backups of our 100 MS Exchange Mailboxes with a skriot. (the exchange server is on a different server). Yesterday only 30 mailboxes will be backuped. Today no Mailbox will be backuped with this error: 30.07.2010 00:20:30: Copieing from MaMu on EDOM04 T-9: Create MAPI session failed: Exchange MAPI/CDO may not be properly installed. scan incomplete, error -3420 (unknown). Do you have a solution? We did the mailbox backups for over one year without en error!!! Thanks Tim Quote Link to comment Share on other sites More sharing options...
tim2008 Posted August 4, 2010 Author Report Share Posted August 4, 2010 Hello, in my case I have to reebot our exchange server and know I can see and backup all my ms exchange mailboxes with retrospect. I think it was a ms windwos update. Tim Quote Link to comment Share on other sites More sharing options...
