Your IT or human resources department may keep some of your profile information in separate systems, for example your profile photo or your name or title. If you're not allowed to change this information yourself, contact your human resources department or admin to have them change it for you.
Why can't you just give me the name of who to contact?
We would have liked to give you the name or the email address of who to contact, but Microsoft doesn't have this information. Below are some suggestions that may help you find out who your admin is.
How do I find out who my admin is?
When looking for your Office 365 admin to update certain information, reset your password, delete an account, or do other tasks, here's some pointers to who you should contact:
Universities and schools: Contact your technical support team. Usually you can find a link on your university site. At smaller schools, there may be just a couple technical people who have admin permissions.
Large businesses: Contact your internal help desk / technical support.
Small businesses: Contact the business owner / co-owner. Often they give admin permissions to their IT consultant who does all the computer maintenance work for their business.
By default, the person who signs up for and buys an Office 365 for business subscription gets admin permissions. That person can assign admin permissions to other people to help them manage Office 365 for their organization.
If you don't know who to contact at your work or school for help, try asking the person who gave you your Office 365 user account and password.
