You can delete
an e-mail account when the account is no longer needed. You can not
delete your default account.
Warning:
Make sure you download any mail that you want to keep, as deleting
the account will delete all of the mail still in that account. You can
not recover this information once the account has been deleted.
To delete
an e-mail account:
Click on the
Add/Remove Accounts link in the Mail area.
Click on the
