Configure SSL for Outlook Anywhere

  • Artikel

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

You can configure the /rpc virtual directory to use Secure Sockets Layer (SSL) for Outlook Anywhere. By default, when you install the Microsoft Exchange Server 2010 Client Access server role, a virtual directory named /rpc is created on the default Internet Information Services (IIS) Web site on the Exchange server.

Use IIS to configure SSL on the /rpc virtual directory

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "SSL for Outlook Anywhere" entry in the Client Access Permissions topic.

If you are using IIS 7.0 or a later version, follow these steps:

  1. In IIS Manager, select Default Web site or the Web site on which you're hosting your Outlook Web App virtual directories.

  2. In the Web site Home pane, double-click SSL Settings in the IIS area.

  3. In SSL Settings, select the Require SSL check box.

    Note

    The Require 128-bit SSL option is not required. However, if selected, this option helps to provide increased security.

    Note

    If you are using an SSL certificate that was created during Exchange Setup, an error message notifies you that the certificate is not a trusted certificate. Make sure that you trust the certification authority (CA) that issued the certificate, or use an SSL certificate that is trusted by your CA.

  4. Under Client Certificates, select Ignore.

  5. In the action pane, click Apply to save your changes.

If you are using an earlier version of IIS than IIS 7, follow these steps:

  1. In IIS, select the Default Web site or the rpc virtual directory, and then click Properties.

    Note

    If you want to configure SSL only for Outlook Anywhere, select the rpc virtual directory under the Default Web site. Otherwise, you'll configure SSL for all virtual directories that are hosted on the Client Access server.

  2. On the Directory Security tab, in Secure Communications, click Edit.

  3. In Secure Communications, select Require Secure Channel (SSL).

After you complete this procedure, your /rpc virtual directory is configured to use SSL.
