Outlook Anywhere uses the HTTP protocol to encapsulate RPC information for sending

between the Outlook client (version 2003 and 2007) and the Exchange Server 2010 server. For

this service to run properly the RPC over HTTP Proxy service has to be installed on the Client

Access Server. This can be achieved either by adding this as a feature via the Server Manager,

or by entering the following command on a PowerShell Command Prompt:

ServerManagerCmd.exe -i RPC-over-HTTP-proxy

When the RPC over HTTP Proxy is installed use the following steps

to configure Outlook Anywhere:

1. Open the Exchange Management Console;

2. In the navigation pane, expand “Microsoft Exchange On-Premises”;

3. In the navigation pane, expand “Server Configuration”;

4. Click on “Client Access” and select your Client Access Server;

5. In the Actions pane, click on “Enable Outlook Anywhere”.

6. On the Enable Outlook Anywhere page enter the External host name. Make sure that

this name is also available in the certificate you created on the previous Paragraph. Select

the authentication methods used by clients, i.e. Basic Authentication or NTLM authentication.

For now leave these settings on default and click Enable to continue;

7. This will activate the Outlook Anywhere service on this service, and it may take up to 15

minutes before the service is actually useable on the Client Access Server. Click Finish to

close the wizard
