Extending Active Directory schema Progress

Asked By 0 points N/A Posted on -


I get the error message “Extending Active Directory schema Progress ……………………. FAILED Active Directory operation failed on mail.mydomain.com.jo” When I try to install exchange 2007 into windows 2008 Service pack 2 environments, where exchange 2003 Service pack 2 is installed is on the only DC.

The error mentioned above is not retainable, and the parameter is not correct.

The response from the active directory is: LdapErr: DSID-0C090A85, comment: Error in attribute conversion operation, data 0, vece.

Any form of help with this error will be appreciated.

You need to check which current Exchange software you have at the moment. There are Exchange versions that will affect or will give you problems when you try to install the 2007 version. This occurs because the active directory scheme is not updated and cannot accommodate the 2007 version.       

To solve this, go to the Exchange Management Shell and run the Setup.com/prepareschema before you install your Exchange version 2007.
