We have a client whose machines are in workgroup mode so no AD or any on premise infrastructure. We are looking to add them to Azure AD since they already have E3 licenses and are using Office 365. My questions are:
1. Will their logins change on their machines? i.e. currently they sign in as somerandomname, will their computer login change to firstname.lastname@example.org for their computer? I am just thinking if we will need to do a profile migration to preserve all their settings?
2. What Office 365 licenses are needed to achieve this? They have E3 and are on Windows 10 Pro. Do they need Windows 10 Enterprise to join Azure AD?
Thanks in advance
