The tutorial documentation (https://learn.microsoft.com/en-us/azure/active-directory/saas-apps/sharepoint-on-premises-tutorial) changed about 5/5/2021, so I have adjusted my claims section in azure AD
It seems like the email claim is no longer required (?) and I have removed it from the above Claims list. Based on the tutorial and https://learn.microsoft.com/en-us/sharepoint/user-profile-sync) - I expect the Work Email to still be populated.
This article also suggests "Typically, user profiles are created automatically for all accounts that are created in Microsoft 365. For organizations that have a Microsoft 365 Education subscription, user profiles are not created for new accounts by default. The user must access SharePoint once, at which time a basic stub profile will be created for the user account. The stub profile will be updated with all remaining data as part of the sync process."
I am using a developer tenant - I noticed that the user shows up in Central Admin; Manage User Profiles once the user has signed on to SharePoint on-premise the first time.
Update: after the users first signon and having checked their profile existed in Central Admin; Manage User Profiles - I ran the full synchronization timer job - after this job completed, the "work email" is still not populated.
Do I need to set anything up in Central Admin, for the User Profile Service Application - under Synchronization "Configure Synchronization Connections"? Currently this area is empty.
Any advise is appreciated.
