I have a new install of Exchange 2013, and have added 4 authoritative domains, now I am adding mail boxes. If I want to have an info@ email address on each, how can I accomplish this? It seems like the first works fine, then when I add the second it appends a number to the user name like info2@ and so on. is that just for the domain controller so it does not have dupe user name? Or have I configured something wrong?
I am a bit lost and would love any kind of guidance.

Every Exchange mailbox is tied to an Active Directory user account, and user accounts have to be globally unique; you'll need a different account for each mailbox, like:
I suggest you first create the user accounts in Active Directory, and then create the Exchange mailboxes by linking them to the already-existing users.
