Thunderbird account does not respond
I am running MicroSoft Windows10, 2004 version update on an HP. I recently upgraded Thunderbird to 78.1.1 and it seems that since then I can not reach my previously working Thurderbird account. No incoming, archieve, trash, junk, nothing.
I have a laptop also running Windows 10, 2004 ver, also with Thunderbird 78.1.1. Both have the same account settings, both incoming and outgoing, but the laptop CAN receive emails and the desktop can't. Both are running AVAST! virus protection, as well as utiltities. What is wrong? Any suggestions?

As you are already able to connect then it is not a TLS issue. The TLS fix only works if the server is not up to date to use TLsv1.2 and you are stuck in a continuous attempt to connect. This is not the case.
Check to see if you have a filter applied. On the 'Quick Filter Bar' there is a Pin icon - tooltip 'Keep filters applied when switching folders'. Is it is shown as highlighted? Click on that 'pin' icon to remove the filter.
Check to see there are no other filters selected on the Quick Filter Bar.

Try to change in THUNDERBIRD preferences editor security.tls.version.min from 3 to 1
From the menu at the top right, go to Options. Scroll all the way to the bottom and click on Config Editor. Skip past the warning. Scroll down until you find security.tls.version.min (or paste security.tls.version.min to upper frame) Double click on it, and set the value to 1
Mozilla disabled TLS 1.0 and 1.1 in the latest versions of Firefox and Thunderbird. Thunderbird 73b and above. This causes issues with anyone connecting via SSL/TLS/StartTLS to services uses 1.1.
Before I try that let me tell you what I found.
I went the EDIT tab on the Menu Tool Bar. Then pick Folder Properties. In the box that appears "Repair Folder" box appears. This makes the folders contents reappear but, it doesn't save and reverts back to it's missing state when the folder is closed. It can be re-repaired but always disappears when closed. Does that help?
I haven't tried your suggestion yet.

The "Quick Filter" was the answer. I must have clicked something somewhere that activated this thing. All is well in email land now. Thanks a lot!.
