Thunderbird can't connect to Yahoo email server

After years of working flawlessly today I turn on my computer, start Thunderbird and see the following Alert pop up-

"An error occurred during a connection to pop.bizmail.yahoo.com:995

Peer reports incompatible or unsupported protocol version

(Error code: ssl_error_protocol_version_alert)"

I click on OK and the same message pops up another 3 times (Thunderbird is managing 4 email addresses for my business, hosted on Yahoo email).

I called my website host and they tell me it is nothing on their side. No changes were made overnight.

Where should I begin?

So the instructions to back up my data were no good as my version didn't have the Export function. However I back everything up to two locations weekly, one being a complete mirror installation on another PC so I was not overly worried about that.

I went with the upgrade instructions here- https://support.mozilla.org/en-US/kb/upgrading-older-version-thunderbird#w_if-you-are-on-a-version-older-than-60

I downloaded 12.0.1 and all the others up to 60.9.1 then went through and installed each until the mail server connection problem resolved, which happened on 45.8.0. I am stopping there, the look and feel is still fundamentally the same as what I was used to and miracle of miracles the search function with this version performs as I wanted. I don't know when the behavior reverted to this but I did upgrade to at least 14.0 back then and it was still fubar.

Interestingly I never got the alert pop-up with any of the upgrades, you could just see down the bottom of the window that it was "Connecting to..." and it would just sit there like that until I exited.

Thank you for your assistance.

What is your Thunderbird version ? ( Click on Help and then About )

Do you know the Thunderbird update history  ?

1) Tools , Settings, General, scroll down to Updates section and then click on "Show Updates History" Upload screen shots of Thunderbird updates history ( the last 3 updates is enough )

Verify your Thunderbird tls version :

1) Click on Tools, Settings, General and scroll down to the last line

2) Click on Config Editor ...

3) in Search Preference name type in : tls.ver

4) Take a snapshot and upload here.

I have been using 9.0.1 forever and stopped it from automatically updating.

Short version why is that Mozilla broke the search/list function on the next release and tried to tell me it was a good thing. If you had more than 10 results when you got to the bottom of the list and clicked "More" it shows 10 more results but returns the view to the top of the search results so you have to scroll through all the ones you already viewed before you got to the new ones. If you search results were more than 100 it was a huge waste of time.

9.0.1 would (and still does) display the next batch and the view stayed where you were so you only need to look through the new results, not the entire list again.

If something in 9.0.1 has now decided to not work anymore (there is no tls.ver in about:config on my install) that may explain it but by the same token I am not sure downloading and installing ver 142.0 will actually happen without breaking my installation.

9.0.1 is a very old version. Very likely 142 will not work and might even corrupt your data.

Before attempting to do anything, please backup your Thunderbird profile carefully in 2 different locations. https://support.mozilla.org/en-US/kb/thunderbird-export#w_creating-a-backup-of-large-profile . I suggest that you should also ( additionally to the export method ) use the "Creating a backup of large profiles" method even if your profile is less than 2G. For method "Creating a backup of large profiles" , you should stop thunderbird before making the copy.

Once the backup is complete, Ideally you should test the backup on another computer (if you have one) . If you have this possibility : 1) Download 9.0.1 from https://archive.mozilla.org/pub/thunderbird/releases/9.0.1/ 2) Install 9.0.1 on the other computer 3) Use this method to test your backup https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer 4) Backup and Restore tested successfully. At this point you have successfully tested the restore on the other computer 5) Upgrade your thunderbird from thunderbird slowly release by release suggested by Thunderbird until your profile is fixed : meaning : click on Help and About and click on Update. Test your connection after each updates, This may take a while. This is the prudent way.

These are my suggestions.

Maybe other peoples on the forum with more knowledges can help you better.
