Have a problem with Exchange and don't know why and how to resolve.
We have an Exchange 2003 server. All were fine until a few days ago that it failed to create an email address for a newly added user.
Usually, Exchange will give an email address to a new user within, say minutes but this time it has taken almost 24 hours and still no email address been created. If I go into User Properties the Email Addresses tab is blank.
No change to any Email Policy whatsoever. The Recipient Policy is still there and I have already manually rebuild the Recipient Update Services, and ran the Mailbox Management Process.
Can any expert shed some light as where else I can look at please? I can probably create the email address manually but I want to understand why Exchange fail to do that in the first place in case there is something fundamentally wrong with it.
Thanks in advance.
