New External Sharing Experience - when is a Guest account created?


hi there,


we are testing the sharing configuration in OdFB and SPO.

We configured "Users can invite new an existing guests".

In ODfB i first share a file with user He gets the invitation and then the access code.
No Guest account is created.

Then i share another document with user which is an external O365 User. This user also gets the invitation, and then the access code.

Now a Guest account is created for this user.


What is the exact algorithm behind this. are Guest users only created for O365 (School and Work Accounts)? Can I prevent that Guest Users are created at all for users invited by standard users?
