I keep getting error messages like below..... up to 50 a day where my Thunderbird is not syncing with my hotmail email. I can not force it but just wait until it happens to automatically sync. It keeps getting worse every week and I just got a notice from Microsoft that they will no longer accept third party programs that do not support modern authentication after September 16. I love my Thunderbird. What can I do to ensure access to my hotmail with Thunderbird?
