I'm new to exchange (better with postfix), so I hope this is something simple I'm missing that will solve this.

I'm having trouble adding new mailboxes to EMC. According to the documentation I was left, the user gets created in AD, then, in EMC under Recipient Configuration>Mailbox>New Mailbox>User Mailbox I should be able to select "Existing Users" and select the user.

Unfortunately, the new users are not showing up there. I tried deleted a user and it still shows up there. I verified that all services set to automatic were started (can't remember now which it was, but a blog somewhere mentioned a particular service that I made sure was running). There has been ~72 hours since the last AD changes, which means it should have had time to replicate.

The one place that DOES see all the changes is the "Find" option under Recipient Configuration>Mailbox. The new users are there, and the deleted ones aren't. Why those don't show up in the other menu I don't know.

If someone could point me in the right direction I'd much appreciate it. If there's any pertinent info I left out please let me know.

Just to give you an idea, once I get through this step of user creation I have to manually run scripts and perform various actions on two different linux boxes and then call a third party to add the recipients to cloud based spam filtering... In other words, I'll be redoing the Exchange set up later this year, but for now I need it to work.

Edit: Solved.

Root cause: Exchange server was also an AD server (I don't know why); when I (a couple weeks ago) did some testing and restored from a snapshot, it buggered all replication to/from our other DC's, and I didn't notice until I tried to add a user, as everything else was working.

Fix: There were some registry values to delete, services to stop/start, and a few reboots.
