I have been using Thunderbird for over 5 years. I am presently using version 128.11.1esr and I update it often. Many e-mails have been put into an "Archive" folder but I just noticed that all of the items put there are now gone. The "Archive" folder is empty. The account that this is attached to is AOL, xxx@verizon.net.

Are there any thoughts on how this could have happened? I am hoping I can get the items back.

Thanks for your thoughts, Steve H.

On a new Thunderbird install only some of the subdirectories are being displayed. This is only happening on one email account (xx@live.com). This happened before and I think it had something to do with a filter but I can't locate the issue.

Thunderbird is not synchronizing with Mailfence. My other email accounts (Outlook, Gmail) work fine. TB connects to them, downloads message headers and displays the number of messages correctly. With Mailfence, the messages stop at "connected to imap.mailfence.com" and stalls there. The message disappears after a few seconds and nothing else happens. This happened this morning when I first launched TB. I then got an update to 128.11.1. No change. I did receive the Windows Update 2025-06 Cumulative Update sometime overnight prior to launching TB.

After working fine for years, Thunderbird stopped receiving email from my POP accounts a month ago and I haven't been able to get it to work since. After weeks of experimentation and frustration, the only way I can get TB to download POP mail is to install and run it in Windows Safe Mode with networking. However, once installed in Windows Safe Mode, TB run in Windows normal mode will successfully send messages from each account.

It would take pages to describe everything I've tried, so I won't. The results of all the tweaking and updates is the system specs below.

OS: Windows 10 Home (x64) version 22H2 AVS: BitDefender Email: Thunderbird 102.15.1 Add-ons: None Theme: Default Accept cookies: Always Exceptions: (added any that seemed even remotely associated with issue) https://accounts.google.com https://mail.google.com https://www.googleapis.com https://pop.gmail.com https://pop.gmail.com:995 https://smtp.gmail.com https://smtp.gmail.com:587 https://pop.centurylink.com https://pop.centurylink.com:995 https://smtp.centurylink.com https://smtp.centurylink.com:587

Hardware acceleration: Off

Gmail POP server: pop.gmail.com Port: 995 Security: SSL/TLS Authentication: Oauth2

Gmail SMTP server: smtp.gmail.com Port: 587 Security: STARTTLS Authentication: Oauth2

CenturyLink POP server: pop.centurylink.net Port: 995 Security: SSL/TLS Authentication: Normal password

CenturyLink SMTP server: smtp.centurylink.com Port: 587 Security: STARTTLS Authentication: Normal password

I'm at a total loss as to what I've missed or where to look next. I would appreciate any help.

What can I do to get this to work? Or is Thunderbird unable to access gmail?

Why doesn't Thunderbird block spam and junk mail? It often tells me that "Thunderbird believes this message is Junk," and I right click "Mark" and tell Thunderbird the message is "Junk," but the sender is never blocked. How many times must I tell Thunderbird that a sender is spamming me?

Why is it so difficult to block a sender who is spamming me? With other email clients, just one marking of "Spam" is enough to block that sender?

How do I tell Thunderbird to block a spammer?

I don't even know how to explain what happened - I just know this is my booked jobs for the rest of the 2025!! The folders are "greyed out" and it says "0kb"

I see the emails on webmail though - but not my own answer emails and not in folders (= very messy)

I'm in the process of cleaning up Thunderbird e-mail before moving to a new computer. I started with 11,593 e-mails in my Inbox and 7,799 e-mails in my Sent folder. I'm now down to 7,634 in my Inbox and 4,965 in my Sent folder. I've allocated 2 weeks for this process and found that it's taking me about 3 hours per day to meet my daily goals. I'm finding that I'm spending at LEAST half the time responding to "Empty-Trash/Compact-folders" requests. There are times I can delete 50 e-mails at a time without getting a request. Other times I will try to delete ten e-mails and get the request. With the old version of Thunderbird I could literally delete hundreds of e-mails at a time. Can you help? Russ Bukwa Yardley, PA ps. I have intentionally given you specific numbers. Based on my software- and test-engineering experience, I speculate you need to create a stress test to solve this nagging problem.

I have Comcast as my internet service provider. I use Thunderbird to download a copy of my e-mails from their server and send e-mails out through their server. Until about a month ago, Thunderbird, which I used for many years will not send my e-mails but will still allow me to receive my e-mails. When I try to send an e-mail, I get an error message that says Login to server smtp.comcast.net with username (then my e-mail address).net failed. I had read on Google that Thunderbird was having some trouble and one of the fixes was to uninstall Thunderbird and reinstall it. Also, to check my settings on my computer which I did and nothing has worked. When The message doesn't go through, after this failure message, I then get this message "Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.comcast.net. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'. I tried changing my password and it did not help. I also contacted the Comcast security team which was able to help me with a previous Thunderbird issue but not this one. They said the problem was with Thunderbird this time. Can anybody assist me with this please?

How do I remove any vertical lines or other notations from replies or forwards. It is all very distracting.

I hope this request can be seen by developers.

Thanks.
