When a custom recipient is created in Microsoft Exchange, the recipient is
considered to have one e-mail address that Microsoft Exchange will pass
mail to. This is also referred to as the target address for the recipient.
This e-mail address appears on the General property sheet when looking at
the properties of the custom recipient.
Microsoft Exchange supports creating additional addresses for recipients.
This is done through the E-mail Addresses tab when you view the details of
a recipient. This functionality gives Microsoft Exchange the ability to
deliver mail to a user who has multiple addresses.
The Microsoft Exchange Administrator program also allows a user to send
mail with a reply address that differs from the e-mail address that
Microsoft Exchange uses to deliver mail to this recipient. This address is
selectable when there is more than one e-mail address of a single type. The
"Set as Reply Address" button is used for this purpose.
For additional information about fixes related to the use of multiple
e-mail addresses and the target e-mail address, please see the following
