The official overview is on this web page:

Someone attempting this procedure will be presented with the required
legal agreements as they go through the steps.  I looked but I couldn't
find a simple web page with all the terms of service.

That discussion, in bug #41386, was about some of Google's email
services.

This discussion is about Microsoft's email services.

No.  GUID here refers to a Microsoft-assigned public identifier.

Microsoft's implementation of OAuth2 provides an application
identification option that is different from the one that Google
provides.  It is the "public client application" option that was
identified by David and discussed in this thread.

With this option, there is no secret code, only the Microsoft-assigned
public identifier that identifies Emacs.  In principle it would be
possible for Emacs source code to include that public identifier since
it is not meant to be kept secret.
