Can't edit "name" of email address

[G-knee]

I am trying to edit the "name" of the email address. But it still
keeps coming up the old way. It is very important. It's a matter of
keeping or losing a friend.

I am trying to edit the "name" of the email address. But it still
keeps coming up the old way. It is very important. It's a matter of
keeping or losing a friend.

What version of Outlook, what type of account, and where are you trying to
make this change?
