I am working on a sharepoint online tenant which is under "Office 365 Enterprise E3" plan. and when i click on a username inside a sharepoint site, i will be redirected to the user's delve page. which contain info such as :-
- the user's direct manager.
- the employee which have are under the user.
- the user's email, phone number, job title.
so my question, is from where we can change these information? is it something managed/covered by sharepoint online or by online active directory ?
second question, in general who have the permission to modify the above users' information?
Thanks
