In active directory for server 2003, I add a new email address, set it as the primary address, delete the old email address and hit apply. This seems to work, and even if I close active directory and open it again, the changes stick. However, when i log off the server and log back on, the old email address reappears and is set as the primary address. The new address still remains, but it is no longer set as the primary address. Does anybody know why this weirdness is happening?
