Exchange aliases disapearing for users

Posted on 2007-10-11

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.

    It could be the RUS, but what do you mean by aliases?

    Do you mean that your user accounts have and and one of those is being removed?

    If you can get more specific, we can show you how to rebuild your recipient policies to work properly.

    Alternatively, if you have a very small number of users, you can open each one and tick "do not update based on the recipient policy" on the bottom of the email addresses tab

    I started to respond to you and then I noticed something, the accounts where the address had been removed, didn't have the Automatically update email addresses based on recipient policy checked. Those that had it checked still have the desired address.

    Forgive me if I state the obvious but if I check that box to update email addresses based on recipient policy, I shouldn't lose any more jbloggs type addresses?

    However, I'm the only one who goes in and would pay attention to that specific attribute. If that option hadn't been checked for some time why would the address suddenly disapear? RUS seems to be working and I thought it was something that was updated daily?

    That is quite bizarre.  Are you the only admin?

    What email addresses would jbloggs have?


    What does your recipient policy look like?

    I'm thinking that one of the other admins is suffering from "amnesia" because nothing else makes sense. The only logical explanation is that an admin went in and removed the address. They simply didn't document the change. I'm awarding points because of the lead to the recipient policy option.

    Thanks for the help.
