Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hello Sam,
I’m Segunfunmi, an Independent Advisor and Microsoft user like you. Thanks for posting the query here in this forum.
To change your Microsoft 365 account name, you need to follow these steps:
Log in to the Microsoft 365 admin center as a global admin.
Select Users > Active users and choose the user you want to change.
Select Manage contact information or Manage username, depending on what you want to change.
Change the display name or the email address, and save the changes.
Restart your PC and sign out and sign in again to your Office apps to see the new name.
If you have already followed these steps and still see the old name, it might be a cache issue. You can try clearing your browser cache or using a different browser to see if that resolves the issue.
I hope this helps! Let me know if you have any further questions.
Kind regards, Segunfunmi.
