Microsoft Outlook will attempt to determine settings for the new Exchange account automatically.  For this step, the instructions depend on whether you have Autodiscovery set up:

NOTE: If an Autodiscover record is configured for the domain name, Outlook will determine settings automatically. You will get a prompt. Select the option Always use my response for this server and click the Allow button.
If no Autodiscover record exists for the domain, MS Outlook 2011 will prompt you for the server name.
Please use server name: https://webmail.dataoncloud.com/EWS/Exchange.asmx
