My father has just got a new computer and wants to download all his old talktalk webmail messages to outlook. The new ones are coming through fine. How does he do this? I'm not on talktalk so can't explore this myself.
However, if the mail messages have been downloaded to the previous computer's Outlook email program that was set up as a POP3 account and are only on the previous computer then he'll need to follow the Microsoft advice here to export the mail and import to Outlook on the new computer.
