Rastor9 1 Report post Posted August 11, 2010 I have installed SP3 on my Exchange 2007 server and now my Retrospect client claims that it can't "reserve backup client, error -505 (backup client reserved). I have started/stopped/restarted the Retrospect Client to no avail. Two weeks ago I had finally gotten the backup system to correctly view/backup individual mailboxes after many install/uninstall of the MAPI CDO programs and copying the files to the SysWOW64 folders. I have double checked the file locations etc for all the steps, and nothing there changed so what is up now? Share this post Link to post Share on other sites
