Many Lotus Notes proxy addresses appear in the properties of a user account in a domain where Exchange Server 2003 is installed

When you view the E-mail Addresses tab in the username Properties dialog box of a user in the Active Directory Users and Computers tool, you notice that many Lotus Notes proxy addresses appear in the E-mail addresses list. Additionally, the number of Lotus Notes proxy addresses increases for this user account every time that the Microsoft Exchange Server 2003 Recipient Update Service runs.

This problem occurs if both of the following conditions are true:

• The user account does not have a first name or a last name specified in the username Properties dialog box in the Active Directory Users and Computers tool.
• The Lotus Notes Address proxy e-mail address specifies the first name and last name variables. For example, you use a Lotus Notes proxy address that is similar to the following:
  &g&s/First Administrative Group/corp@contoso.com
  Note The g variable stands for "given name" (first name), and the s variable stands for "surname" (last name).

This problem occurs because when the Recipient Update Service runs in the domain, it examines the current proxy addresses to determine if they have been modified. In the scenario where you stamp a proxy address that specifies the last name and the first name but the user account does not have a last name or a first name, the Recipient Update Service determines that this proxy address has been modified. Therefore, it creates an additional Lotus Notes proxy address every time that it runs.
