As of two days ago, I used to be able to create an Active Directory user account, with an exchange account selected, and it would create the users mailbox. Now that mailbox doesn't get created. I have tried the following after the account was created:
1. Logon as the user, successful.
2. Send an email to the user, unsuccessful - delivery error
3. Restart exchange services - no errors logged in Event Viewer
4. Restart server - no errors logged in Event Viewer
This is Exchange Standard 2003 SP2 running on Server 2003 SP2.
