Ok, I am to the point of moving mailboxes. when I try to move I recieve an error 9162. Error: Cannot complete the operation because "Server" does not have the attribute 'msExchResponsibleMTAServer' set ot becuase I dont have permissions to read it. I have found the corresponding MS article Q294172. It tells me I need to add the attribute. My 1st question is do I add the attribute to my Ex 5.5 server or my 2k3 server. My second is how do I type the command out? It shows in my ADSI edit screen that it is distinguished with no value. Please help!! I am so close!!
