So you’ve installed Exchange 2007 sp3 update rollup 1 and you go to do a new receive connector and it fails…
“I am unable to make a receive connector for an application relay. No matter which settings I use I get this:
After install this rollup the command ‘New-ReceiveConnector’ is failed: ‘Error:
Active Directory operation failed on [dc]. This error is not retriable. Additional information: The parameter is incorrect. Active directory response: 00000057: LdapErr: DSID-0C090C26. comment: Error in attribute conversion operation, data 0, v1772
The requested attribut does not exist”
“Just to update – once I iuninstalled Rollup Update 1 for Exchange 2007 SP3 I was able to add the Recieve Connector. So some change in there seems to cause the problem.”
After someone updated their AD schema to Exchange 2010 sp1 the New-ReceiveConnector doesn’t fail.
So you have a couple of choices here… wait for update rollup 2 for Exchange 2007, uninstall update rollup 1, or last but not least you could install that schema update but I think it’s safer to just roll back and hang tight.
