    Hi. I'm Brian and I'll try to help.

    Who is your mail provider - that is, what follows the @ in your address? What type of account (POP, IMAP, Exchange) have you configured? Was there ever a time when you were able to perform this function? Did anything change on your computer between then and now?

    Was this answer helpful?
