[Exchange] Email addresses not added to new user

[Thozama Nonxuba]

Hi
I have an Exchange 2003 SP2 server and 3 total domain controllers, with one
in a remote office. All domain controllers 2008R2 and above.
Yesterday, I created 3 new users but they have no email addresses. I have
sent emails to the new acccounts but they bounce.
What could be wrong?



Thanks.
