I'm not an Exchange admin, my guess is a bad migration, but that's just a
guess. I'd post about that in an Exchange admin newsgroup.

After looking at it he saw that all new Exchange Users had the correct
alias, but all the users that were migrated from Exchange 2003 had the
IDs. The Alias field in Exchange has the correct name. Is there something
in AD that might have not been update correctly?
