Thunderbird Support Forum

Since starting my Win 10 Pro computer today, Thunderbird 115.4.2 (64-bit) has been "dead in the water". When it's launched, it posts the customary "Downloading Message 1 of [N]" status report, but then hangs right there, takes 3 or 4 minutes even to (re-)populate the tabs and panes that had been open, doesn't get past the alleged first new msg even in 15 or 20 minutes. When it does populate the Inbox pane, it shows no messages newer than last night just before shutdown. Very sluggish response to cursor, too: for ex. 30 seconds from clicking on a msg title in the Inbox pane to displaying that msg, even longer to bring up Help/About (with "Not Responding" shown in its title bar.)

  I get my mail through gmail's IMAP server but prefer to use Tbird's interface . Thinking there might be something evil about the first msg that was waiting to be downloaded, I used gmail's web interface to review everything new since last night, deleted several msgs that had attachments, then started Tbird again.  No change.  Can't even get Tbird into the "Work offline" state because it attempts download-of-new-msgs immediately after being started.
  The only consistently effective way I have found to STOP the hung Tbird is through (Classic) Task Manager's "Processes" list, which usually shows five or six "thunderbird.exe" instances.  After selecting whichever has the largest memory allocation I click on "End Process."
  This all "feels like" a bollixed internal state.  Does Tbird store internal-state information in its own file, or is it buried in the Registry?   If I attempt restoration from a backup, which files are needed; or is that unwise?
 I see there is a mid-April update available to 115.10; would installing it reset current messed-up internal state, or will that already messy situation prevent the update?   Is there any risk of losing my Inbox, Sent, etc contents?

Thanks!!!

In general, I like Thunderbird, have used it for years. But if there's one thing that will make me abandon it it's that incoming links are not hyperlinks, they're just text. From what I've read, that's deliberate. If not, how do I make incoming links be links? I'm really ready to move on.

First, I am supporting a family member, who has TB configured on two separate machines. Configuring for Comcast IMAP+SMTP, in the usual manner; nothing esoteric about that, all very routine.

Machine A seems to be working okay, no errors. TB up to date on this machine, connected over an ethernet wire, if that makes any difference.

Machine B, getting spam prompted over IMAP 1014 errors. No other information is provided than 1014.

I have tried dropping the account configuration hundred percent, restarting TB, re-adding the account configuration, to no avail. Still spam 1014 errors.

I did happen to notice TB needed an update, so I did that as well. Still 1014 errors.

I have also tried dropping that email saved password from the saved passwords, and responding to the subsequent re-enter password prompt. Also to no avail.

What if anything might have changed, and how can we contend with this? What is so corrupt, do we need to be mucking around in any AppData files, roaming files, etc?

We are not the only ones, apparently, to have bumped into this issue. Not sure if this is also Comcast specific, since a recent TB and/or IMAP specification change, i.e. maybe we try with a gmail account, for instance.

Wondering also, is it IMAP and/or Comcast somehow tieing Machine A to the IMAP and not releasing that association? Knowing a little bit about IMAP in this regard. And/or somehow now prohibiting Machine B+ from establishing a connection?

I've been reorganizing my folders, and while working on this, I will occasionally find that I can no longer create a new folder or rename an existing one, or, somewhat worse, when I rename a folder, it will disappear, along with the messages that were in it. The messages that were in the missing folder don't show up in a search, and aren't in trash.

If I close Tbird and quickfilters, and sometimes also restart the computer, the functions again work as they should (but the missing folders do not reappear). Rebuilding the parent folder doesn't recover the missing subfolder. The problem can happen when Tbird is the only open application.

Any idea what can cause this? Or where the missing emails might be?

Thanks Kent

Greetings: Here is an error message that is now so common that I can no longer send email to any account. Also, I have not been able to send email to any gmail account for last year or two. Please help. Error Message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <MattMcKeegan_PLS@proton.me>... Relaying denied: You must check for new mail before sending mail.. Please check the message recipient "MattMcKeegan_PLS@proton.me" and try again."

Thanks. Matt.

Since Thunderbird was upgraded to 115.10.1 (64-bit), it now fails to send SMTP messages with the following error.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) ***.mail.pairserver.com was lost in the middle of the transaction. Try again.

This affects all six(6) accounts in Thunderbird, all of them can receive and edit e-mail messages; however, all of them fail to send e-mail messages.

Prior versions of Thunderbird have worked with this configuration for many years.

Other e-mail clients such as Evolution do not have this issue and I have confirmed with my provider that Thunderbird is no longer sending e-mails.

Any thoughts on how to roll back Thunderbird until this issue is resolved?

Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

Error message 'side by side configuration error'. I've been advised to re-install Thunderbird but not sure if I will lose my many thousands of emails and my address books etc.

A few months ago

If I deleted an email or moved it to another folder - on my apple app for any of the accounts that I also have on thunderbird

The changes would sync seamlessly - a few seconds after I deleted or moved an email on my apple iPhone mail app - on my laptop - thunderbird would show the same changes.

The same worked the other way if I deleted or moved an email on thunderbird on my laptop - my iPhone would show the changes in seconds.

However now if I do the same on my iPhone The changes do not show up at all.

BUT if I do the changes on my laptop - they will show on my iPhone. It just doesn’t work if I do the changes on my iPhone.

Is there a reason for this?

Have several folders and sub-folders for saving important emails in Thunderbird. One choice for saving subfolders. my master email address. I can save to this folder but cannot retrieve those emails. Attached is a screen shot. How do I retrieve emails from those folders???

My wife is an ardent and long-time Thunderbird user. She has tens of thousands of old emails organized into dozens of folders. Recently she noted that many folders contained scrambled emails. For example, an email titled "The race to re-design sugar" from Sept. 2020 now contained what looked like content from an email from Office Depot. See below for a short piece of the body of the email. Anyway, I ran Thunderbird's "repair folder" function and not only did it not unscramble the emails, it also seems to have deleted any emails prior to 6 months ago. Fortunately I've got her T-Bird profile file backed up daily, so was able to restore the original (but scrambled) emails. Any thoughts? I use outlook, but I've got pretty good PC skills if you need to take me into the weeds. Thanks!

Example of one of the scrambled emails: 'From - Sun Feb 4 12:28:28 2024 X-Account-Key: account5 X-UIDL: AEZHkUhl+QCXZb/zNgpcWOY28vQ X-Mozilla-Status: 0009 X-Mozilla-Status2: 00000000 X-Mozilla-Keys: Received: from 127.0.0.1 by atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com pod-id atlas--sbc-production-bf1-7448fd4479-zt82t.bf1.yahoo.com with HTTP; Sun, 4 Feb 2024 20:27:34 +0000 Return-Path: <error@em.officedepot.com> X-Originating-Ip: [20.57.66.208] Received-SPF: pass (domain of em.officedepot.com designates 20.57.66.208 as permitted sender) Authentication-Results: atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com; dkim=pass header.i=@em.officedepot.com header.s=officedepot; spf=pass smtp.mailfrom=em.officedepot.com; dmarc=pass(p=NONE) header.from=em.officedepot.com; X-Apparently-To: xxxx.xxxx@att.net; Sun, 4 Feb 2024 20:27:34 +0000 X-YMailISG: T.w7qP0WLDtIndBfVsii11yVLG9YUwuh8bXrpNWGHf2Ezt9n W35tfL8ReGJq0phUGg1KeSNel41YbOoogg21rDC6q0i7xvo0jIbdikP0kWCS '

I have a Google Calendar, in which I manage My Tasks. I can't see my existing tasks in Thunderbird, and I can't add new tasks to the Google Calendar. New Task in Thunderbird is greyed out and the field next to it has the writing: "Please select a calendar that supports tasks".

I have seen that many had the same issue and understood that it is linked to how My Tasks in Google Calendar itself works. Is there really no workaround whatsoever?

If not, how can I manage tasks and share them with someone else (who uses Google Calendar or Apple Calendar, but does not use Thunderbird)?

Thanks in advance for your replies!

I tried to move (copy) Proton mail emails to Google Gmail without success. I searched support for help but found no articles that worked. I started to use proton Mail but was unimpressed and need to move (copy) the Proton Mail emails to my Google Gmail. Any help would be appreciated. Thanks, Lou

Hi, I have upgraded my computer and Thunderbird, however only the INBOX folder is loading.

I have followed the instructions to migrate the folders from the 'Profile Folder' on the old computer, the data has transferred but is not organised as folders, as on the old computer and of course on the main server.

I don't mind if all the data is not on my computer so long as the Folders are there, empty or not but organised in as they are on the main server.

I'm wondering if I selected an incorrect setting while setting up the account within Thunderbird on the new computer.

Thank you and kind regards, Mark.

Thunderbird 115 included in 24.04 LTS installation.

My profiles are located on the SD card working well on other two laptops running ubuntu 22.04. Swap SD cards between two laptops is my way of working with Thunderbird since 13.04.

After installation 24.04 LTS (and Thunderbird 115 included). Following the instruction for adding old profile to the new Thunderbird. Help->thunderbird information->about:profiles. Creating new profile. 1) Using the function CHOOSE FOLDER indicated the path to the profile /media/VB/AB49-E208/Thunderbird profile 2) The path to the folder shown by Thunderbird is different (and strange): /run/user/1000/doc/58235/Thunderbird

When looking into the directory tree the folder is empty (obviously). Thunderbird therefore cannot reach the profile located on SD card and doesn't work.

QUESTION: Is there any way to overwrite the profile folder path in Thunderbird 115 ?

Thunderbird seems to be hung up in a circular reference. It continues to download 1 of 2 and 2 of 2 repetitively, nonstop. This is continues process without ceasing. It seems be slowing do the whole system.
