UsingAutoCorrect in OutlookEmailAccount

Let's say my hypothetical name is Lavde Lagle

It should actually be written as "Lavd? Lagl?" (e with the accent)

I am able to auto correct my name in Microsoft Word but my question is -

If I would like the accent to appear in my name in my Outlook "E-mail Account" {In Outlook click on 'Inbox', go to 'Tools' then 'E-mail Accounts' and where the name appears in the 'Internet E-mail Settings (POP3)} how do I get the 'e' in my name to show as an ? in the 'User Name'? That will enable my e-mail recipients to see my name as "Lavd? Lagl?" INSTEAD OF " Lavde Lagle".

I would appreciate you help.

Thank you.
