Set a Primary Address
The first address created for each address type is the primary address. The primary address is the address that appears in the From field, when a mailbox-enabled user sends e-mail. For mail-enabled recipients, the primary address appears on the Exchange General tab, in the recipient's Properties dialog box.
By default, if a newly created e-mail address is the only one of its type, it is the primary address and will appear as bold. If there are multiple addresses for an address type, you can designate one address to be the primary address. You can only select a primary address if there is more than one e-mail address for an address type.
