Hi, could not update Exchange 2007 SP1 to SP2 because of Obj_Class_violation. Found out it could be because of Ferrari Fax Office Master software (http://my.opera.com/RavenOverride/blog/2009/08/27/installing-sp1-sp2-for-exchange-2007-issues-part-2), so deinstalled everything, also the whole UM-Role, but no help. Found some more information about missing auxilliary Class attributes http://social.technet.microsoft.com/Forums/en/exchangesvrdeploy/thread/1f432502-9aaf-439a-8cb8-101b38efb695 - where ok, update still not possible.Any idea, how to solve the problem and to find out what causes that Object Class Violation? Is there a tool to find out whats going while the update runs?Servers are all 2003R2x64.

Hi, 1. First please ensure that you have uninstalled Ferrari Software for FAX/SMS. 2. Please check with adsiedit.msc under the "Microsoft Exchange" the Organisation to see if we have entry for a Fax/SMS Software 3. Please check to verify if we have third party connectors under the Organisation Connectors for this third party product with the Sub-Object "Settings" Regards, Xiu

Hi - got a new Tool from Ferrari to remove all the "bad" entries in the AD, than the update worked. The Tool ist part of the the Ferrari Officemaster Exchange Administration Tool, is called ADCleanup.
