Outlook Anywhere on Exchange 2007 (RPC/HTTPS)

How to Enable Outlook Anywhere

Before You begin, to enable Outlook Anywhere, you must follow these steps in the following order:
Install a

1. 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 Exchange Server 2007 Client Access server role installed.

When you install Exchange 2007, 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.
