Thunderbird was configured to send & receive via Cox /yahoo mail. Worked until recently but can no longer send or receive.

Please advise. Best Regards, Leigh Wax

I am using Thunderbird (ver. 128.1.0esr) as my email client. I have two Internet Service providers: Xfinity(Comcast) and AT&T. I can't send emails when using AT&T but can when using Xfinity. Can receive emails OK on both. Why is this?

Hi,

   I've used Thunderbird on Linux for about 20 years and it has worked flawlessly connecting to my ISP mail for both sending and receiving messages. About 2 weeks ago I tried to send a mail and got an internal error back from the ISP SMTP  server that the message was being blocked as possible spam. POP continued to work fine.

I tried renaming my local .thunderbird directory and downloading the latest version of Thunderbird to try a fresh install. It behaved exactly the same way.

   The frustrating thing is that KMail, an alternate Linux mailer works fine with the exact settings that fail on Thunderbird. I can also send mail from my phone when connected to the same ISP wifi as the Linux machine. 
   I am not sending out messages to large groups of recipients. It will fail (but work in Kmail   and K9Mail on Android) with a trivial test message to myself. 

Any ideas how I can troubleshoot this? I like Thunderbird but can't use it if I can never send mail.

Thanks!

I am a 20-year (give or take) user of Thunderbird, and it is getting almost unusable.

I am hopeful someone can help.

A lot of context....

My principal account is at Comcast (POP3; normal password), but a consulting gig has caused me to add a Outlook account (POP3; OAuth2). And I think that (along with Thunderbird updates within the past year) are the cause of my issues. And the only circumvention I have found is restarting. And yes, I have a large, multi-decade collection of e-mails in about 100 local folders.

Issues that appear intermittently:

1) Pauses (for instance, while composing e-mails) lasting up to 15 seconds where Thunderbird is unresponsive to keystrokes or other UI gestures. 2) Sometimes there are permanent "(Not responding)" lockups. Also there are times where the address book is inaccessible until Thunderbird is closed and restarted. Restarting is also the frequent cure for the persistent authentication issues. 3) Inability to access address book implicitly or via menu item 4) On start-up, generally both accounts get authenticated, but I keep getting nags to enter the Outlook password - If I ignore the nag, it pops up every couple of minutes. If I enter the password incorrectly, it tells me, but if I enter it correctly the login screen goes away, but login screen reappears within a few minutes. 5) Likely in conjunction with (4) above, I intermittently cannot send e-mails outbound to the Comcast account, with Tbird complaining about authentication; reentering the Comcast password does not help until I restart. 6) If (5) above happens, when I restart Tbird, I have to reenter Comcast passwords, even though I always select "remember password" 7) nstmp folders keep getting created.

Thank you for any assistance you can offer.

Hello, I am desperate. After an update today, my profile is gone. It would be no problem to set up the mails again. But I had saved a lot of mails in local folders for years and I'm afraid that I won't be able to access them if I set everything up again. Unfortunately, I can't do anything with the help articles because they are too technical. I think I have at least found the location of the locally stored mails. How should I proceed so that I can access them again? Thank you so much in advance, Klaudia

Apart from my main email address, I also have a Gmail address. Recently I stopped receiving and cannot send any emails from that gmail address. I keep receiving a pop-up window every10 minutes asking me to update my gmail parameters. The links given in that pop-up window lead nowhere. I followed instructions given in "Automatic conversion of Google mail accounts to Oauth 2.0 authentication" but the problem subsists. I am trying to attach a screenprint of the pop-up window but can't upload the .PDF. Please help, thanks

Hello, we are running Thunderbird 128.1.0osr (32-bit) released on 8/6/24. Ever since the upgrade my husband's email has not worked correctly.

Around that same time, he received a pop up within the Thunderbird app asking for donations from Thunderbird. The popup would not go away and my husband lost a ton of his email.

Ever since these two events his Thunderbird email won't work correctly.

Messages since 8/4/24 at 6:32 am DO work correctly. Emails prior to 5/6/23 also work correctly. Any message in the time period from 5/6/23 at 11:26 am to 8/4/24 does NOT work correctly.

We are having the same trouble with the sent items folder.

We use a third party email that we import into Thunderbird and have used the third party email and Thunderbird since at least 2020 and never had this problem.

We can see all the message headers in our email list, but when we click on the email, nothing shows up. It will briefly say "message loading" at the bottom corner, but the email is totally blank. Furthermore, the message that peeks out at the bottom is the last email that we clicked on from the section of emails that does work. It is not changing to the email we are actually clicking on.

For example: lets say we have an email with message header "thank you for your order" received on 8/15. We click into that and it pulls up fine.

Then we go into older email from 7/31. The message header is "hurry sale ends today". If we click on that, it will say "message loading" at the bottom corner. However, the message preview at the bottom of the screen still displays the from/to/subject from the previous email we viewed from 8/15 "thank you for your order" (the message from 8/15 shows as blank though).

Even if we double click the message from 7/31 that we are trying to view, it just pulls up a blank screen. The bar at the top will briefly display the correct message title that we are trying to open, then it just blanks out.

Steps we have taken:

1. In Account Settings/Privacy I clicked to "allow remote content". This made an improvement as prior to this we were having the same problem even with recent messages. We could see one or two messages that had just arrived, then the third message we couldn't see. We have messages set to delete on the server after so many days. So I think it was able to recover the message that were still on the remove 3rd party server.

2. We moved a lot of the emails into archive folders as I thought the inbox may be too large. That didn't make any improvement.

Thanks for any help you can provide. My husband has a lot of really important information in his emails that he needs.

Hello, I recently replaced my old PC with new desktop running WIN 11. Although I am able to receive Outlook email. However, when I attempt to send mail from my Outlook address I receive an error message: "Unable to authenticate Outgoing server smtp.office365.com..." The smtp settings are attached. Firewall - Windows firewall Antivirus - MS Defender Antivirus OS - Win 11 v 23H2 Thunderbird - 129.0.1

Thanks, Richard

my head is spinning with trying to understand. i changed the authentication to oauth2 but can't seem to find out whats wrong and my dislexia is making it so hard to figure out.

My colleague, like me has been using Thunderbird for years, thank you. He has just purchased a new printer (Epson 2200) and he can no longer print any emails. Clicking on print brings up the box with 'Save to pdf' the ony option. We have gone into Troubleshooting Information and the printer appears in the print_printer line. We have also tried clearing the 'Clear saved print settings'. After we restart TB, no change, still unable to print with 'save to pdf' the only option. We have removed and reistalled the printer, which will print anything else outside of TB.

TB is up to date with the Nebula version. Windows 11 on new Acer Laptop.

Can you help?

Thank you

Using Thunderbird 128.1.0.esr (64 bit)

I have an IMAP account. Under Settings_Copies & Folders I have the option 'Place replies in the folder of the message being replied to' checked.

After sending a message Thunderbird can't save it to that locvation. I get the option to save to a local folder.

Subsequently I then try to move or copy the email to my desired IMAP folder. This fails with no error message - the email stays in the Local Folder.

How can I resolve this?

Yahoo Acnt. #1 messages being duplicated in Yahoo Acnt. #2 in Thunderbird ONLY

I have tested, and tested and tested. Checked settings EVERYWHERE. Delete and removed, reinstalled, etc. etc. etc.

Additionally, Thunderbird will NOT retrieve inbox messages from YAHOO for account #2

I have DETAILED (including screen captures) the conditions in a document and made it available here.

NEED SOMEONE ABSOLUTELY BRILLIANT TO SOLVE THIS ONE !

I would like to connect to Suddenlink.net via Optimum.net. It does show up on Optimum.net account on web page. I have a screen shot of the constant results of my days of efforts. I have two other connections via gmail.com and it works fine. I have people who are still using Suddenlink emails to me and I would like to see them on Thunderbird. Thanks for the fine software and any help with this. //... Joe

Nyc.rr.com cannot send email I can receive email. Everything seems to be set correctly as you can see in the screenshot. Please help. This is a new pc that I am trying to setup. Thank You

The latest rev is VERY slow (several seconds) compared to prior revs to process email changes within INBOX (OPEN, MOVE, DELETE, etc.)

Something new is going on internally to the program while the hour-glass appears for a few seconds more than before (I did not change any settings w/ latest upgrades).

I have got many thousands of emails. From time to time my inbox gets full enough for a warning sign to come up - so I have a clean up by deleting and/or saving to a folder within "local folders" and I regularly clean out my deleted folders and recompact.

However in the last few days I have been getting a warning tab come up saying "75% full" fairly randomly - in other words it seems to be independent of whatever folder is active at the time.

Does Thunderbird have a maximum capacity including all local folders? There are many emails (including attachments, of course) which I do not want to delete whether for archive or for nostalgic reasons.

If there is a maximum overall capacity is there any way of "exporting" folders of emails with their attachments to free up space for the program but leaving me able to invoke these emails should the need or occasion arise?

I am using Mac OS Ventura 13.6.9. I have been a Thunderbird user for many years. Since this last update, I have started having issues where not all emails are displaying. Seems like most recent emails open correctly, but when I get to emails that are a day or 2 old, I get the the following banner across the top of the screen when the email opens, but can't open the remainder of the email.

I have attached a screenshot to show what I am seeing.

I am using gmail and I can access the emails in gmail, but not in Thunderbird. What is the fix for this?

Thanks

Laura

A few times now I've had a batch of incoming e-mails where the date, sender, header information are all there but the body of the e-mail shows: FXCG9w89iTyF8D70T5uihi9D instead of the message. I don't know what this means or why it happens. Can you explain and help me find a solution?

PDF Viewer just loads a white screen on the 130.0b1 (64-bit) build, I have to manually save the pdfs and open them with another program.

I have restarted TB several times, restarted the computer, checked for any and all malicous firmware and still its not working

Do you know, why Thunderbird does not display message content or displays strange characters? We only have this problem on one computer. On the other everything is OK.
