Action: Create an Office 365 cloud-only administrator - When using Active Directory Federation Services (AD FS) with Office 365, be sure to add at least one cloud-only user in Office 365 and assign that user the global administrator role. This will enable your organization to access your Office 365 environment in the event your AD FS farm or network fails. You'll want to add an admin with, for example, the UPN/email address of [email protected]. Using the Office 365 default domain of onmicrosoft.com will enable access to Office 365 and address issues that might arise. Learn more.
