Guest Users vs. External Users

At this point, I cannot see any difference between the two wordings: it appears to me that "Guest User" and "External User" have exactly the same meaning, with the former being only a more "modern" wording. Am I correct?

On the other hand, "Guest User" is frequently used in Microsoft documentation when speaking about Groups, and this IMO creates a lot of confusion with "Guest Member", which is a separate concept (in fact, I believe that a "Guest Member" of a Group is always a "Guest User", but not necessarily viceversa).

Am I missing something?

  • We use the terms interchangeably at Microsoft as well. External user is an older term from back when all "guests" in the directory authenticated outside of the home tenant. When we added support for managed guest users (i.e. the user authenticates inside the home tenant), the "external" piece stopped making sense and "guest user" was born. 

     

    And as with many of these types of things, we ended up using both names to refer to the same set of features. If there is a feature/scenario where this language does make a difference, we try to make sure it's clearly labeled to avoid confusion.
