Mailbox name

I am presuming that you are using Apple's native Mail application. If so, follow these steps:

1. Open Mail
2. in the taskbar, go to Mail>Preferences
3. Navigate to the "Accounts" tab (@ symbol)
4. Select the account that you want to rename
5. In the "Description" box, type the new name that you would like to give to the account
6. Press enter

The account name should now be changed. I hope that this is helpful.
