Hi, I noticed that some of my email accounts stopped working. Thunderbird just doesn't connect. It is only with certain accounts, all from the same provider. However, they only stopped working after a recent upgrade. So I decided to test this out. I uninstalled my current version (78.1.1) and installed version 68.11. I then opened v68 with a new profile and added one of my email accounts. Everything worked perfectly fine and the account imported and download the emails for it. I then uninstalled v68 and installed v78.1.1. I then opened the new profile that just worked with no issue and it now would not work in new version of Thunderbird. I removed the email account and deleted associated data and then imported the account again. This time I get an error. The new version of Thunderbird just refuses to connect for some reason when the older version connects no problem. I have attached a screenshot of trying to import the account in v78.1.1 and the corresponding error console.

Most of these issues I am seeing are internet hosting providers that have not updated their security in the past decade or so. StartTLS uses TLS and Thunderbird 78 no longer supports TLS up to 1.1 which was superseded in 2008 with TLS V1.2 and that was again superseded by V1.3 in 2018.


But I checked on the mail server. It was pretty dismal failure as far a security is concerned.

Change the connection security/ SSL to none and you should connect
