Updated Thunderbird to 117.12.2 on the 25 June 2024. Since then I am not receiving emails on my computer. I have actually sent some emails but they don't save into the sent folder and I have had a "Add security exception" warning occured when sending.

So problem is not getting new emails since the latest update was loaded. Thanks Neil

I can't SEND on Thunderbird as of Update to Version 115.12.1 on 6/19. I was able to SEND on June 18th and left town for a week and when I came back could not Send. That could be a coincidence. Have Windows 11, with Defender Firewall and Security virus protection. I have TB version 115.12.2 up to date. I have checked with Spectrum for the correct configuration and currently I have as Description: SMTP Server (on top line); Server Name: Mail.brighthouse.com and Port 465, No Authentication and SSL/TLS. My User Name: e-mail address ends in @tampabay.rr.com and that is the same as shown on incoming server.

My husband just downloaded TB program on his Windows 8.1 which is my old computer that I've been running TB on for 15 years without a hitch!! ''''And he also cannot SEND.'''' It's very frustrating - we've tried changing server settings since Spectrum uses not only Brighthouse (which is the one they say covers the Tampabay.rr.com address) but they also use Mobil.charter.net and also TWC.com. I've tried changing them up but nothing works. I've tried changing Ports and anything I could change I did, but nothing works. I did get a couple of error msgs but they didn't help. Brighthouse timed out and another msg was saying that the email address I was sending as had to match the email address of the authentication and that didn't make sense as I have only had one address & (typed correctly in all places). I have called Spectrum more than once and asked for an upper level, however, they were no help at all saying they have no resp. for 3rd party etc. I HOPE YOU CAN HELP SOLVE THIS MYSTERY. Thank you!

I have TB ver 115.12.2 64 bit. It reports as being up to date. During attempting to make the changes necessary to accommodate Microsoft's Modern Authentication I reach a point where the option to select OAuth2 does not appear in the Outgoing Server SMPT settings drop down menu, see the image. How do I deal with this? Thanks for your help.

Using TBird 15.10.1 64-bit on my Windows 10 desktop system, I find under Tools | Address Book a down arrow to the left of Personal Address Book; clicking on it displays all my created address lists, which are available when I compose a message to send.

Using 15.10.1 64-bit on my Windows 11 laptop, the down arrow does not appear and I have no access to those lists.

Am using IMAP on both systems. Tried importing lists as a CSV file; no effect. How can I get access to my address lists on both PCs?

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

I was looking for an email I expected to find in my Inbox, and found that a message filter was applied to move it to another folder. I can see the filter log entry for this action.

This filter consists of 9 specific email matches ( From "is" ....); the message that was moved is NOT in this filter list.

When I moved the message back to my Inbox, it was moved again.

Any ideas on how to stop this happening? Can I even trust filters?

I recently deleted all my filters as I was not sure they were working correctly, and recreated them carefully. I currently have 10 filters, a few are one off created from a message, and none have more than 10 matching requirements.

I have attached an image of the filter at issue, and here is the filter log entry:

[7/1/2024, 9:40:07 AM] Applied filter "Bad Shopping" to message from grandrr@olypen.com - [RW] RW Potluck Tuesday July 2 at 7/1/2024, 9:19:44 AM moved message id = faecf27e13e90b655df9ff49ee14a5ec@olypen.com to imap://sjstowell1000%40gmail.com@imap.gmail.com/Good Causes & Bad Shopping

Why? Actual bug? DB problem?

All morning I had been receiving and sending emails without issue. Then at approx 12:41 PM EST Thunderbird stopped working. I can send and receive emails through AOL to AOL but they do not show up in Thunderbird. I did not have any other computer issues and did not change any settings. Verizon told me it was an AOL issue, but I was able to successfully send and receive messages with AOL. AOL tried to fix it but ultimately said it was a Thunderbird issue. In the last 6 or 7 weeks I have had issues with Thunderbird. What is going on? Very Very Frustrating!!!

I have done a custom install of TB on D:\ drive, moved Profiles folder to D:\, verified that account settings/server settings have local directory pointing to D:\ drive.

Can I delete all TB files on C:\? TB still *seems* to be using those files. I really need to free up space on C:\ - tiny drive filled with Windows OS, huge D:\ with nothing on it.

Thank you for your time and attention!

I've been accessing ATT.net along with gmail.com for years now. Every once in a while, ATT don't accept my login password? Error message reads: "Login to server inbound.att.net with username pennsynut@att.net failed." And when I "enter new password" with the password from ATT.net, it still don't accept it. I vaguely remember doing something with ATT.net years ago. But why does it keep doing this "login failed"? I ask because if I wait a day, it will re-insert itself. When I check passwords in TB for ATT.net. All it shows is "mailboxc//(mailbox://). The gmails show smtp, imap & oath. But ATT only shows that one. ? How do I get the other passwords in there?

I have set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE in both Thunderbird and Betterbird.

I have created the file C:\Users\MYNAME\AppData\Roaming\Thunderbird\Profiles\r2v9k1zw.default\chrome\userChrome.css

I have successfully entered css into that file that work as expected in Thunderbird v115.12 and has for the past several versions. But I have NOT been able to do anything in that file that works with BetterBird. In fact, using the inspector, I don't see userChrome.css even being loaded! I have also tried starting the file with '@namespace html url(“http://www.w3.org/1999/xhtml”)' but that makes no difference either.

How do I get BetterBird to recognize the userChrome.css file?

I had a POP account on my desktop PC for many years. Recently I purchased my first laptop and decided to go IMAP on it, while retaining my old downloaded emails as an archive on my old desktop PC. I turned off automatically downloading emails in this desktop PC's POP instance of Thunderbird.

(The desktop PC is Windows 10, the laptop is Windows 11.)

I didn't want to transfer these old emails from my desktop PC to an IMAP server, because they weren't organized -- everything was in the Inbox. On the new laptop (and/or on the IMAP server), I am diligent in putting emails into appropriate folders.

My question is: how can I convert the desktop PC to be IMAP while yet retainomg my old email archive, so that I can access those old emails as needed on both desktop PC and laptop PC -- which will both be IMAP?

Unable to fix the side by side error, my only option may be to re-install Thunderbird or migrate to Outlook.

My question is whether its feasible to re-install Thunderbird and still preserve my old profile and emails. I haven't done any backups of Thunderbird but do still have all my emails on the server.

Thanks Lance

PS I have tried all the suggested fixes as shown in the following link to the side by side error: https://support.mozilla.org/en-US/questions/1439559#answer-1659630

I can send emails but when try to receive emails I get Login to server inbound.att.net with username topgun30@sbcglobal.net failed.

I have a verizon.net email account at AOL. AOL now requires use of a one-time-use "app password" to sign in from Thunderbird. This does work but it seems like now I will have to go through this process (going to AOL web mail and requesting a new app password) every time I reboot my computer or restart Thunderbird. Is this true?

I installed the new version of Thunderbird, and it's strange. I can receive emails and send emails, but I'm getting an error message at the bottom right corner of my screen:

Could not connect to the mail server (and then it names my server name) The connection was refused

What do I gotta do to make this go away?

Ever since the last update of Thunderbird, my Junk and Trash folders are empty. When I mark a message as Junk or throw something in the Trash, the messages simply disappear. I have no way of checking the Junk mailbox for messages that might be there in error. I am also unsure whether my Trash messages are being deleted permanently, or whether they are in a hidden mailbox somewhere. Please help if you can!
