Version 45.2.0 (automatically updated) Cannot receive messages since Friday 2016-08-26 Thunderbird was working fine before this sudden change. I can send messages and they are received by the addressees. I can see my messages on the ISP’s email interface. I have been running Windows 10 without any problems since the end of June 2016 I have double-decked my ISP account settings and they are correct. I do not run an antivirus program, except what’s automatically included in Windows 10 updates. My ISP does not offer help with problems specific to Thunderbird. I have even uninstalled Thunderbird 45.2.0 and downloaded a fresh copy. Nothing has changed. I am stumped!
