I have been using Thunderbird for many years for my hotmail account. Today I can not receive messages. I get the following message... Sending of password for user tlpaulsen@hotmail.com did not succeed. Mail server pop-mail.outlook.com responded: Authentication failure: unknown user name or bad password. [Error="ProxyNotAuthenticated" AuthResult=0 Proxy=CO2PR04MB2264.namprd04.prod.outlook.com:1995:SSL]

Not sure what to try.
