What is Outlook Anywhere?
This is a system that lets you connect Microsoft Outlook to to your Exchange server over the web, this means you can connect to to your email, calendaring and tasks etc, without the need for a VPN connection.
Outlook Anywhere with Exchange 2007 (Exchange 2010 Skip to Step1)
If you plan to deploy Outlook Anywhere with Exchange 2007 there is an additional step you need to carry out before you start. From server manager > Feature > Add Features > Add in the 'RPC over HTTP Proxy' feature before you start. (Note: you DONT need to do this if you are running SBS 2008).
Step 1 Configure Exchange
1. First we need to turn it on: from within the Exchange Management, expand Server configuration > Client Access > Select the server in the central pane > Select "Enable Outlook anywhere" in the action pane.
2. Enter the publicly addressable name of your Exchange server, for this example I'm using NTLM authentication > Enable.
Note: The external host name is the address that you would type into a browser to contact the Exchange server i.e. for Outlook Web Access http://mail.domaina.com/owa. This would mean the public name is mail.domaina.com. This name must be the Common Name (CN) on the Exchange server's digital certificate.
3. Take heed of the information, nothing's going to work for 15 minutes (Even Exchange is telling you to apply the cup of coffee rule) > Go and have a hot milky beverage.
Note2: To work internally make sure that mail.domaina.com resolves to the INTERNAL IP address of the Exchange server.
6. You may also want to execute the following command. Particularly if you use SBS, which has a habit of setting remote.publicdomain.com as the default outside name.
Step 2 Configure Outlook for Outlook Anywhere
1. In this example I'm using Outlook 2010 and the mail profile/account has NOT been setup, if you already have an account edit it, select "More Settings" and jump to number 4.
Note: To support Outlook Anywhere you need a minimum of Outlook 2003 SP2
2. If you are setting up your Outlook client internally, the autodiscover service should fill in the details for you.
3. If it auto configures the settings for you, tick the box to manually configure server settings.
4. More Settings.
5. Connection Tab > Tick "Connect to Microsoft Exchange Server using HTTP" > Click "Exchange Proxy Settings".
7. Security Tab > Ensure "Encrypt data between Microsoft Outlook and Microsoft Exchange" is selected.
8. Restart Outlook - you may be asked for your username and password again this is normal.
