Quick Answer

Your Microsoft 365 work account is managed by your organization. You can change your password, update your profile photo, and set up MFA. You cannot change your email address, add aliases, install unapproved apps, or modify security policies — those require IT.

Frequently asked questions

Why can't I change my profile picture?
Some organizations lock profile pictures to maintain a professional directory (or automatically import your official badge photo). If the 'Change photo' button is missing, IT has restricted it.
How do I change my last name in my email address after getting married?
You cannot do this yourself. You must submit an HR/IT ticket. Changing your core email address (your User Principal Name) requires an administrator to update the corporate directory.
