Where the does sender's name in an e-mail come from and how can I change what name I send?

Question

At work, we use Google Apps to host our e-mail and Outlook to access it. I have a user who recently changed their name. I changed their e-mail address and their account name, but when they send e-mail their old name still appears, no matter whether they send it using Outlook or the gmail web client. For example, e-mail from them in the Gmail web client reads Oldname newemailaddress@example.com instead of Newname newemailaddress@example.com. I'm trying to make the user's new name show up when they send an e-mail.

Where is the sender's name stored? Is it a part of the e-mail specification, stored in some header somewhere, or is it stored in the e-mail client?

If it's possible, how do you change the sender's name in Gmail?

Answer 1

In Gmail it's under Settings, Accounts and Import, Send Mail as

Answer 2

If you're sending from Outlook (SMTP) you'll need to make sure you change the account settings to reflect the name.

1. Go to File->Info->Account Settings.
2. Find the SMTP account in the list and click 'Change...'
3. Under 'User Information' change the persons name.
