Hi Walter,

The below article has all necessary information on adding and removing email accounts. The process will differ slightly depending on which type of account you are using (POP, IMAP, Exchange, EAS) if you're not sure which type of account you're using, simply navigate to control panel > mail > click accounts and this will tell you the account type.

Let me know if you have any issues.
