Remember, unable to download messages so sending an email will not be seen.

This is a web forum, not a mailing list.

I am asking why TB will no longer download emails after the last update.

Did you read the article linked above?

I had this problem with version 45. Thunderbird update changed some of my incoming Account Preferences. With the help of my ISP IT tech, we got TB-45 to download messages. Now the headers are all downloaded, but often hangs on one header and will not display the message. I can delete some messages by reading the email header in the Inbox section, bu I still do not see the message.

So here is one solution and another question.

jlh68,

please start a new topic for your problem. https://support.mozilla.org/questions/new

Do you mean post a new Thread, or a new topic? It seems my post was the same topic as the one I commented on. I have gotten the 'post a new topic' on every post I comment on. I guess this forum wants every post to be a unique thread, even if on the same topic as others already posted?

You're hijacking someone else thread. This is why you're being asked to start your own for your problem.
