The Exchange 2010 hybrid server that you're configuring in your existing Exchange organization will handle mail transportation and routing of messages between your on-premises and cloud-based organizations. Therefore, you'll need to modify the e-mail address policy for your users and mail-enabled objects. Adding a shared service-routing namespace as a custom secondary e-mail domain for your recipients enables them to receive e-mail messages that use the service routing namespace.

How do I do this?

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "E-mail address policies" entry in Mailbox Permissions.

You can update your existing default recipient e-mail address policy using the Exchange Management Console (EMC) on your Exchange 2010 hybrid server or any other Exchange 2010 server in your organization. We recommend updating the default recipient e-mail address policy using the EMC on your Exchange 2010 hybrid server.

  1. In the console tree, navigate to Organization Configuration > Hub Transport on the hybrid server.

  2. In the result pane, click the E-mail Address Policies tab, and then select the default recipient e-mail address policy.

  3. In the action pane, click Edit.

  4. On the Introduction page, click Next.

  5. On the Conditions page, click Next.

  6. On the E-Mail Addresses page, select Add to enter an e-mail address for your service-routing namespace.

  7. On the SMTP E-Mail Address dialog, select the E-mail address local part check box and select Use alias. Additionally, select Select the accepted domain for the e-mail address and then browse to select the FQDN of your service-routing namespace from a list of accepted domains. For example, Click OK after selecting the service-routing namespace in the Select Accepted Domain dialog and then click OK to continue.

  8. Click Next to continue.

  9. On the Schedule page, select Immediately in the Apply the e-mail address policy section.

  10. Click Next to continue.

  11. On the Edit E-Mail Address Policy page, review your configuration settings. Click Edit to apply your changes to the e-mail address policy. Click Back to make any configuration changes.

  12. On the Completion page, review the following, and then click Finish to close the wizard:

    • A status of Completed indicates that the wizard completed the task successfully.

    • A status of Failed indicates that the task wasn't completed. If the task fails, review the summary for an explanation, and then click Back to make any configuration changes.

  13. Click Finish to close the wizard.

How do I know this worked?
