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:

  • InfoDomA -> info@domainA.com
  • InfoDomB -> info@domainB.com
  • InfoDomC -> info@domainC.com

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.

  • If I add them as new accounts, will I be able to use info@ for each, or will it only work if I setup the accounts first? – box86rowh Nov 21 '13 at 19:55
  • You'll be able to use info@ email accounts for each domain. No problem there. Just that the user account has to be unique (within the AD domain). EDIT: you'll also most likely have to uncheck the auto apply email policy and then add your "info@" and remove the old "info2@" – TheCleaner Nov 21 '13 at 20:06
  • I will go ahead and try this and let you know how it goes – box86rowh Nov 21 '13 at 20:16
  • I ended up setting up organization units for each site, this is working good. – box86rowh Nov 22 '13 at 15:14
