I have this problem where when adding a user in Active directory and creating an exchange alias/email for the user during mailbox setup the mailbox never gets created in the exchange. This just started happening in exchange 2003 on standard server, the RUS is also not updating the users email addresses and not creating an x.400 stamp. dcdiag and netdiag show no errors. the user is able to logonto the domain. thanks alot, -------------------------------------------------------- http://www.netdigix.com
