Connecting to Other Messaging Systems

Enable Address Types in Recipient Policies

Recipient policies define how non-native e-mail addresses, called proxy addresses, are generated for recipients. For example, a policy might specify that Exchange users' Groupwise addresses should take the form "Exchange.First Administrative Group.username." During directory synchronization, each Exchange recipient's primary proxy address is exported to the other system, so that users on that system—using their native addressing—can send mail to Exchange recipients.

Policies contain a list of address types, such as GWISE, and associated address templates, such as "Exchange.First Administrative Group.username." When you install a connector, the address type and template of the other messaging system are automatically added to the recipient policies used by your organization. You can customize the template to match your naming conventions.

Note   When you install Exchange, it creates a recipient policy called Default Policy, which applies to all Exchange users, groups, contacts, and public folders. You can add additional policies that target a particular set of recipients.

If you add additional policies, they are assigned a higher priority than the default policy, and their rules take precedence. In an Exchange 5.5 and Exchange 2000 mixed environment, the e-mail address generation policy defined on the Exchange 5.5 Site Addressing property page is replicated to Exchange 2000 with the highest priority.

As a step in your connector configuration process, you must enable the address type on recipient policies. Once enabled, proxy addresses can be generated from the template for each Exchange recipient, and Recipient Update Service automatically updates all Exchange recipients with a proxy address of that type. You should enable the address type in each recipient policy that affects Exchange recipients you want to synchronize.

Caution   During directory synchronization, the connectors also create secondary proxy addresses for recipients that are imported to Exchange. These addresses, which appear without boldface in the E-Mail Addresses tab of the recipient’s policy, are used as unique identifiers for the connectors to correlate synchronization with the other directory. You should not modify or delete these secondary proxy addresses; in general, you should only delete addresses that you create manually.

To enable address types in a recipient policy:

  1. Start System Manager
    On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.
  2. Navigate to Recipient Policies.


    1. Recipient Policies
  3. In the details pane, right-click the policy, and then click Properties.
  4. On the E-Mail Addresses tab, check the box next to the address type. Then click Apply. Recipient Update Service will automatically generate addresses for all users, contacts, groups, and public folders in Active Directory.
  5. Important   Although Active Directory supports unicode characters, the e-mail address must use the Western European character set. In other words, do not use double-byte characters.
