If you’re on Exchange 2013 or Exchange Online, you can use the EAC to easily search recipients.

If the recipient is not hidden from Address Lists/ GAL, the email address resolves to the recipient’s Display Name. Here are a few different ways to find out whether an email address is already used, and the recipient it belongs to.Ĭreate a new message in Microsoft Outlook or OWA, enter the email address and then press CTRL-K. Every once in a while you try to assign a particular address to a recipient in Active Directory Users & Computers, only to be told someone already has that address! Email addresses need to be unique - two recipients can’t have the same email address.
