I am working on a sharepoint farm 2013 on-premises, and i have the following settings for the user profile service:-
- currently i have created a user profile service, but there is not any sync with AD.
- so currently when a new user access any site collection, a new user profile will be created automatically for the user.
- now some users who have their user profiles created inside the user profile service, have left the company. so there are no accounts for them inside the AD.
now i am not sure what will happen if we chose to sync the user profile service with AD? so what will happen to the user profiles inside the user profile service which no longer exists inside the AD?? will they get removed from the user profile service? if the answer is Yes (they will be removed) then what will happen to the items and pages which have the createdby and modifiedby equal to the users who left the company ? will it be set to system account for example?
