I am adding some users in a default Sharepoint online group (Visitors of Sharepoint Site).
I am doing this from the interface Groups > Visitors of tenant Site > New > Share tenant Site window (watch the picture for precise info):
Add People in a Sharepoint group interface:
Everything works except for one user that I can't find, we will call him Franko. I have tried to look with first name, last name, email... Nothing.
My question is, from where SharePoint is looking for users? Azure Active Directory "Users" group? Because this Franko is in AAD Users Group.
Can anyone help me with this issue?
