Thanks Microsoft for partnering with a competitor to squeeze out the small guy reselling domain names. Also great job selecting ONE registrar instead of allowing a number of different options. And finally - whatever you do folks DO NOT BUY OFFICE 365 THROUGH GODADDY! They LOCK YOU IN! You cannot choose a different provider for your licensing, or purchase different licenses than what GoDaddy provides. And the only way to migrate your tenant off the GoDaddy profile is to create a NEW Tenant and backup and restore your mailboxes and files. Want access to the Admin interface for Office365 on your tenant? Nope. GoDaddy provides a feature limited bastardized version of that interface that does NOT allow you control over your tenant. Want to work with a reseller to help you customize and manage that domain? Nope can't do that either. You have to buy a license for them to allow them access.
Stop competing with your resellers. We ARE your lifeblood and every time you pull crap like this it reduces our trust in you and makes us want to look for other platforms. Google is out there. Amazon is out there. You are not the only game in town.
