To change the name shown on Microsoft services (including Outlook.com), update the Microsoft account display name. This is the name that appears to others in email and across Microsoft products.
- Sign in to the Microsoft account.
- Go to the account profile page where personal info is managed.
- Select Edit name.
- Change the current name (for example, from "Shrinivasa Kapinishetty" to "Shrinivasa") as desired.
- Select Save.
Notes:
- It can take up to 24 hours for the updated name to appear everywhere.
- Changing the display name does not change the account’s email address or Xbox gamertag.
For legal name issues specifically tied to certification profiles or exam records (for example, if the name must match government ID for proctored exams), use the dedicated credentials support channel referenced in the context.
