A Perfect Example

A common question among Microsoft Exchange Server administrators is, "How do we use Exchange Administrator to add multiple SMTP addresses?" The answer is, "You can't." The trick is to modify an object's Secondary-Proxy-Addresses property. This solution might not seem obvious, but Exchange Server stashes proxy addresses in this attribute.

Suppose you're BigCorp's Exchange Server administrator, and you're setting up a mailbox for Joan Smith. You've set up autonaming so that Joan's SMTP address will be [email protected]. Because you know that exact naming details are difficult to remember, you also want to let Joan get mail at [email protected] and [email protected]. In a Comma Separated Values (CSV) file for Joan's mailbox, add the Secondary-Proxy-Addresses header property and appropriate values, as follows:

Obj-Class,Mode,Directory Name,Secondary-Proxy-AddressesMailbox,modify,Joan Smith,smtp:[email protected]%smtp:[email protected]

Notice that in the content line, SMTP is lowercase because these addresses aren't usable as reply addresses. Microsoft Exchange Administrator displays such an address in lowercase roman type.

Suppose you want to make this change for all users on the server. You can easily complete this task.
