I am unable to activate an email address that was previously in use. I deleted the User, and since added them back to our active directory, but I am unable to assign them their previous email address. We have recently moved our exchange server and upgraded to 2010, also our Domain Controllers have been moved.  exchange_error

    You say that you can not add the user the previous email address, but the output appears to be a failed email to the address?

    If this is the case, it's most likely not because of the email address not being assigned, but because you are using the previous entry in your Nk2 cache from outlook to send the message.  Internally it uses the SID, not the address to route.

    You need to clear his name from your cache, Start typing his name in the To field, when it appears, highlight it and delete it, then type the full address, or select him from the GAL.
