Email connection to service provider

Fixed. Talked to Talktalk tech. No help but sent me instructions on setting up account. No help as that's what was there already. However, my wife's account suddenly started working without any changes being made! My view is it wasn't working at their end and he did something without telling me. I recall the same thing happening a couple of years back when it was on Tesco.net (my wife's account again) and their tech support said they sometimes have probs with multiple e-mail accounts on the same landline. Tesco's e-mail service was subsequently taken over by Talktalk and seems to have brought the old problems with it. Anyway, all fixed. Thanks for yr time.

Talktalk won't support Apple's e-mail app. The messages are there on their webmail site so it's working at their end. I've reset the router but it's still the same. When I enter e-mail it puts up a message prompting me to input the password for my wife. When I do that it says it can't verify the account or the password. Meanwhile, mine's working fine. I sent a test message from my wife's account to mine which was received OK but my reply back was not received. I rerun Connection Doctor which now says it cannot connect on my wife's IMAP account.

Normally I do use the Mail app. That is the part which has stopped accessing the mail provider's site. When prompted to enter the password it says it is unable to verify the user or the password. To access the provider's webmail, I use Safari; that part works.
