I get a message that says my server certificate has expired and I can't send or receive emails. I'm ready to ditch Thunderbird. I've had this twice this year.

Good morning
Since this morning (05/03/2026) Thunderbird freezes within a minute or two of opening the program.
Everything in the program freezes up. I cannot even close it.
I am running Version 140.8.0esr on a Windows 10 PC.
Initially I was getting a pop up warning message that ask me to confirm if I wanted to send an email with attachments of over 20 MB. There were 3 or 4 such messages. I had not tried to send such emails.
I checked the Outbox in Local folders for old messages, but it was empty. I also checked the Unsent messages files in Local Folders in the Profile folder. I deleted the Unsent Messages.msf file to no effect. I renamed and replaced the Unsent messages file. Also no change.
I checked for crash logs but there are none.
I have run out of ideas as to what to try next. Does anyone have any advice?

Hello,
Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.
Remembered this old message I got so I went through and deleted my second email address, didn't help.
https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo
Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.
Anyone have any ideas?

Whenever i send a message , it is saved to the 'inbox' previously it would be saved "sent mail". I have verified that TB is configured to save to sent mail but the msg is saved anyway to inbox.
Can some one explain how to get back to saving sent messages to sent mail folder.
In all honesty I find it frustrating to keep moving msgs manually.
need to delete unsent email - how do I access OUTBOX, as it does not appear in my Thunderbird app.
need OUTBOX on my thunderbird email - not there - what do I do to access, need to delete an email that do not want to send

Every time I send a message, it duplicates itself. Any help in removing this problem in the settings will be appreciated. Please keep in mind I'm not that savvy with settings so if you can keep this simple like me, that would be great. I'm using version 151.0 64-bit on Windows 10. Hopefully someone be able to help me resolve this problem.
Thank you, Joe
Please give advice on how I may restore lost emails or at least stop them disappearing

Hello! All the messages in the sent folder have been lost. When I use webmail, all the messages appear normally. I sent a test message from Thunderbird 151.0 (64-bit) / Windows 10 (64-bit) and the message does not appear anywhere in Thunderbird, but I can see it in "webmail". I added the same email account to TB on another PC and I have the same problem. I have deleted this specific email account from TB and reinstalled it, but the problem persists. In Outlook (iPad and PC) it works normally. Other email addresses of the same domain work normally everywhere. The email server provider cannot help me and claims that there is a technical problem on my side. Is there anyone who has any idea on how to solve this particular problem? Thank you.

I have TB version 140.11.0esr (64-bit) running on Win 10. I have multiple accounts and each is set to check for new messages every 10 minutes (nothing else is ticked under "Server Settings). Everything is ticked under "When new message arrives" (and default sound is used).
When new messages were available to download, TB used to play alert sound (and I would know to download new messages) but now TB is sounding (the new messages) alert every time it checks for new messages even if there are NO new messages to download! How do I revert to the alert ONLY being sounded when there ARE new messages to download?
threads are screwing up my ability to communicate with my clients. How do I shut threads off completely forever?
A message posted here in 2015 describes the process but it doesn't work for me. File>New does not offer me 'Mailing List'. Where do I go to find it?

I had to reset my Windows 10 computer and lost all apps and files. I have attempted to download Thunderbird to replace the one that was lost. I had hoped to regain my old emails and files but that is beyond my abilities. I am a senior citizen [81 years] and have been using Thunderbird along with Earthlink mail [which has been recovered along with some of my emails] for over 25 years. I also recovered Mozilla Firefox [with my bookmarks]. Now I need to recover my Thunderbird account with my emails and files. There were many years of emails and files in Thunderbird. Earthlink mail sent me a link on my cell phone that only required me to touch it to install it on my Dell computer. I did not set up my computer many years ago and the man who did set it up is now deceased so I cannot go to him for help. If you can send me a link with which I can recover my thunderbird account along with my files and emails I would be eternally grateful. My cell phone number is [edited phone# from public community support forum]. HELP!!! PLEASE! Thank you very much and GOD Bless You. Janice Chelf, San Antonio, Texas
Why are suddenly are all my emails going right to my trash bin? I did have to change my email password. Could that be the reason?

I'm using Thunderbird from a little time anmd I have a problem with "Unified Folders" After installing it, I added my 10 accounts one by one and found out a problem. Simply Thunderbird doesn't want more than 1 "yahoo" account. I can enter even 15 accounts and Thunderbird can manage all the accounts with "Unified Folders" without problems and I see all the accounts. But if I were to add another "yahoo" account, Thunderbird no longer handles it with "Unified Folders". In fact it disappears and I only see it again if I activate "All Folders". I can't understand why. Maybe I need to setup something on yahoo? Can I solve this problem? Thanks PS: I speak italian.
