I have 4 mail accounts with the same mail provider and I use Thunderbird to access them. Since a few days I get a login failure for one of the accounts. The other 3 work fine. I have not changed anything myself. The error message reads: "Login to server mailin.telia.com with username santamonica@telia.com failed." Below that message there are 3 options; "Retry" "Enter New Password" "Cancel". Retry doesn´t work and when I click on "Enter New Password" I get a frame with the following message: "Enter your password fpr santamonica@telia.com on mailin.telia.com". I enter my password but it still doesn´t work, I only get the initial error message again. I have talked to the mail provider and they say that they can´t help with this since the fault is with Thunderbird. Does anyone have a clue as to what could be wrong, and what I could do to correct this matter?
