I have set up a hosting package with your company and can't figure out how to make my office 365 account use the URL I have set up. So I want my office365 account to be user@astronomicalsolutions.com instead I have user@astronomicalsolutions.onmicrosoft.com. When I go through the office365 Admin panel I get the following error message "This domain name is not compatible with Office 365, please verify that you have typed the domain name correctly or use a different domain name that is similar to fourthcoffee.com"
