Microsoft® Exchange Server 2007 setup cannot continue because the Recipient Update Service (RUS) responsible for a domain in the existing Exchange organization cannot be found.

Microsoft Exchange setup requires that each domain in the existing Exchange organization have an instance of the Recipient Update Service.

If an instance of the Recipient Update Service is missing for a domain, new user objects created in the domain will not receive e-mail addresses issued to them.

To resolve this issue, verify that an instance of the Recipient Update Service exists for each domain and create an instance of the Recipient Update Service for the domains that do not have one and then rerun Microsoft Exchange setup.

To create a Recipient Update Service instance for a domain
  1. Open Exchange System Manager.

  2. Expand Recipients.

  3. Right-click the Recipient Update Services node, click New, and then click Recipient Update Service.

  4. In the New Object window, click Browse to locate the name of the domain.

  5. Select the name of the domain and then click OK.

  6. In the New Object window, click Next, and then Finish.
