For about a month now every time I click on Get Messages I get this error message: "Login to server pop-mail.outlook.com with username (my email address) failed" with the option to Retry or re-enter the password. If I Retry (without re-entering the password), it then correctly downloads my messages but repeats the error and I again need to "retry" just to clear it from the screen. I have 2 email accounts set up in Thunderbird and interestingly the error message points to the account address I'm not using. If I select the other account (then one referenced in the error message) the same error message occurs so it's the same message regardless of which email address trying to access. Any suggestions to fix this? Thanks.
