This article describes how to specify an address book from which to resolve an e-mail address.
There are situations where you have an e-mail address entry for someone in the Global Address List (GAL), and a different e-mail address (such as a home e-mail address) in your Contact list. The address resolution priority is determined by settings in the Microsoft Exchange Server service.
To Change the Address Provider Priority
To view and change the address resolution priority, follow these steps:
On the Tools menu, click Services.
In Services, click the Addressing tab. The address list priority is displayed in the When sending mail, check names using these address lists in the following order list.
To permanently change the address list priority, click an address provider and then click the arrows to arrange the address providers in the order you want to have addresses resolved.
Outlook will resolve the name to the first address it matches based upon the address order.
To Specify the Address Provider in the Message
To specify the address provider in a message without changing the order, follow these steps:
On the File Menu, click New, and then click Mail Message. Click to place the cursor in the To, CC, or BCC field, and type an e-mail address.
If you want to force the address to be resolved from the GAL, type an EQUAL SIGN (=), or if you want to force the address to be resolved from Contacts, type a MINUS SIGN (-).
NOTE: When you use this method, make sure to type a space between the EQUAL SIGN (=) or the MINUS SIGN (-), and the alias that you intend to resolve.
Type the recipient name, or Microsoft Exchange Server alias for the recipient immediately after the character chosen in step 2.
Repeat the process for all other recipients and then send the message.
The address provider order will be overridden for the message currently sent, but this does not make a permanent change to the order specified using the steps in the "To Change the Address Provider Priority" section.
