I am at the beginning of implementing Azure AD Premium in an environment and got hung up on the simple task of configuring Named Location for Conditional Access. Now, this was a minor nuisance at best, but thought I would outline what happened as the Microsoft documentation is a bit misleading.
As a background for those of you unfamiliar, Named Location is a feature of Azure AD Premium that lets you define know locations in your AD tenant. This is used for with Identity Protection and login risk assessments. It can also be part of Conditional Access. For example, don’t force MFA when a user logs in from a Named Location.
