Using New Outlook on Windows for personal email, calendar, and contact management
Hi,
I see the question concerns a new Outlook. I would like to let you know that the name is tied to your email Service Provider, and as a result, there is no functionality to change it.
Could you ask your email service provider for instructions on how to change the name?
If it is an outlook.com email address, I'll share the steps below, since the name syncs from your account
