How to Manually Configure Outlook 2007 for Exchange Online

This will allow you to configure Outlook 2007 manually for companies that do not want to, or cannot, install the Sign On client.

Please understand the caveat of not having the Sign On client: you will not have access to AutoDiscover due to the Sign On client not downloading the required certificate.  This will prevent you from accessing the Offline Address Book (OAB), Free/Busy information (used for meeting invites), and Out of Office (both Out of Office and Free/Busy can be viewed in OWA).
