One of our admins asked why email was bouncing back to folks who have mailboxes in our organization. When I looked I noticed that the emails were being sent to the Exchange alias of the user. This is not uncommon for us however the strange thing is that no one should have removed those aliases. I was able to go into ADUC and put them back, and that fixed the problem.
But my question is, how would they have been removed? There is nothing in a policy that we have that would impact this. Everything looks good on the Exchange server. Is it possible that something could be up with RUS? I'd be really freaked if some process could remove the aliases.
Thanks for the help.
