Enable Outlook Anywhere

[This is pre-release documentation and subject to change in future releases. This topic's current status is: Milestone-Ready.]

This topic explains how to use the Exchange Management Console or the Exchange Management Shell to enable Outlook Anywhere for your organization.

To enable Outlook Anywhere, you must follow these steps in the following order:

  1. Install a valid Secure Sockets Layer (SSL) certificate from a trusted certification authority (CA) that the client trusts.
  2. Install the Windows RPC over HTTP Proxy component.
  3. Enable Outlook Anywhere on a computer that has the Microsoft Exchange Server 2010 Client Access server role installed.

When you install Exchange 2010, you can install a default SSL certificate that is created by Exchange Setup. However, this certificate is not a valid SSL certificate that is trusted by the client. To use Outlook Anywhere, you must install an SSL certificate that is trusted by the client.

To perform this procedure, the account you use must be delegated the Exchange Organization Administrator role.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2010, see Important: Update for Permissions in Exchange 2010.

To install the RPC over HTTP Windows Networking component
  1. Click Start, point to Settings, click Control Panel, and then double-click Add or Remove Programs.

  2. Click Add/Remove Windows Components.

  3. On the Windows Components page, in the Components window, select Networking Services, and then click the Details button.

  4. On the Networking Services page, in the Subcomponents of Networking Services window, select the check box next to RPC over HTTP Proxy, and then click OK.

  5. On the Windows Components page, click Next.

  6. Click Finish to close the Windows Components Wizard.

To use the Exchange Management Console to enable Outlook Anywhere
  1. In the console tree, expand Server Configuration, and then click Client Access.

  2. In the action pane, click Enable Outlook Anywhere.

  3. In the Enable Outlook Anywhere Wizard, in the box under External host name, type the external host name for your organization.

  4. Select an available external authentication method. You can select Basic authentication or NTLM authentication.

  5. If you are using an SSL accelerator and you want to do SSL offloading, select the check box next to Allow secure channel (SSL) offloading.

    Do not use this option unless you are sure that you have an SSL accelerator that can handle SSL offloading. If you do not have an SSL accelerator that can handle SSL offloading and you select this option, Outlook Anywhere will not function correctly.
  6. Click Enable to apply these settings and enable Outlook Anywhere.

  7. Click Finish to close the Enable Outlook Anywhere Wizard.

To use the Exchange Management Shell to enable Outlook Anywhere
  1. Run the following command:

    enable-OutlookAnywhere -Server:'ServerName' -ExternalHostName:'ExternalHostName'-ExternalAuthenticationMethod:'Basic' -SSLOffloading:$false
    Running this cmdlet with the ExternalAuthenticationMethod and SSLOffloading parameters will enable Outlook Anywhere with Basic authentication and no SSL offloading.
