How do I create a new mailing list? I'm trying to follow the instructions here, but with the address book open, I don't have "mailing list" as an option under 'File' 'New'. See screenshot attached.

Thanks for your help.

My user upgraded Thunderbird to v136 and no longer can sync his calendar on our IMAP server (Cyrus). When Thunderbird attempts to log into the calendar Cyrus logs an "Internal Server Error" with the detail

May 5 15:11:39 XXXXX cyrus/https[198300]: badlogin: [10.8.0.10] Basic SASL(-1): generic failure: All-whitespace username.

The user can access their email so their account username/password is stored correctly in Thunderbird, it's just not making it to the calendar subsystem.

Failure is 100%. The user can access their calendar from the previous version of Thunderbird and by using another app on their phone.

1. Thunderbird was not my default mail client in Windows. When I tried to select it as default it did not appear in Windows' list of applications.

2. I tried to find the my profile and it showed where it was - but that directory did not exist. I finally was able to make a new profile and the directory showed up - but then the default-esr profile disappeared and now I can't find it and neither can Thunderbird. Is there a way to find where it went? I don't believe I delete it, it just went away. This is the message I get:

Your Thunderbird profile cannot be loaded. It may be missing or inaccessible

Have always set up accounts so they download all messages to hard drive.

Since 3/27/25, it is as if it never officially logs the downloads as downloaded, so it downloads each day as if it hasn't been done since 3/27/25, marking all of the messages since then as new.

File is very large so want to try fixing without deleting entire file.

Tried the 'repair this folder' but that didn't work.

Having trouble identifying the exact folder on the hard drive to delete since there are several different accounts in the Thunderbird setup.

Thunderbird started crashing randomly about 2 days ago, however, after restart, it would remain running if I switched to troubleshooting mode. I removed an add-on from Bitdefender in troubleshooting mode.

Today I can't even open Thunderbird-- it crashes on launch. It won't launch even if I hit the Shift key or if I turn off antivirus.

Here is the most recent submitted crash report:

Crash ID: ⁨bp-b52cd345-636f-445a-ab4c-764ca0250114⁩

Can someone please give me guidance on what is going on and how to fix it?

Thank you.

I've been having issues with Thunderbird randomly hanging over the last few weeks. It's always been slow to upload all my gmail messages, so I let it get done with that before I start reading. However, now it randomly decides to hang forever. It generally happens when I delete or move an email to another folder. It doesn't complete the function. I can click on other emails, but it doesn't open them. The UI just sits there with the blue progress bar shimmering away, forever. None of the window control work (File, X, etc.). I have to use the Task Manager to end the Thunderbird task. When I start it up again, the message will be moved or deleted, and I can view more messages until it decides to hang again. This happens about four times per day.

I have an MSI GS75 Stealth 9SF laptop, running intel Core i7, Windows 11 (up to date), and the most current version of Thunderbird.

I didn't see anyone else commenting on Thunderbird hanging frequently, so I'm wondering if it's just me.

I have been having much trouble with Thunderbird. The latest problem is with the Sent folder. When I try to Compact Folders I get the message "The folder 'Sent on Local' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I have plenty of disk space and have Full Control. I tried creating a temporary folder and moving all the Sent messages to it, so that Sent had zero messages. I still got the same message. The file listing showed Sent to have a size of 182 MB even though it didn't contain any messages. I've tried deleting sent.msf to force Thunderbird to recreate the index - didn't work. I tried using Repair Folder. That worked, but when I tried Compacting Folders again it found another folder with the same problem. I fixed that one and then it said the Sent folder was bad once again. I'm going around in circles!

I've deleted and recreated scores of .msf files for various reasons, trying to get Thunderbird to work without errors, but as soon as I get one problem fixed, another one crops up. I'd conclude that it's my computer, except that I'm not having any problems with other programs.

Any thoughts on this particular problem or Thunderbird problems in general? Thanks.

It appears that Thunderbird knows how much disc space is required to compact a folder, since it says there is not enough. Could the message say "You must have xxx free disc space" rather than having to use the trial and error method. If this space is 'work space' could Thunderbird be instructed to use a drive other than C: for workspace.

An error occurred when writing to the calendar CanadaHolidays! Please see below for more information.

On calendar properties changed to read-only, still cannot import? Graham

Is there a way to sort Favorite folders? I've tried dragging them to a new order with horrible consequences. Instead of changing the order, the actual folder was moved to a sub-folder position within the actual folder I was trying to move to the position beneath it.

In other words, if I have Favorite folders: A, B, C, E, F, D and I want to move Folder D to the position after C and before E, dragging D to C will cause the physical location of the Folder D to be moved to a sub-folder position of Folder C in the email account.

If you then move it back to it's correct position AND folder D had sub-folders as well, you will then get the error message for any of Folder D's sub-folders: Unable to open the summary file for FOLDER D's SUBFOLDER NAME. Perhaps there was an error on disk, or the full path is too long.

BTW: is there a way to fix that error as well?

I think it started to happen with Version 128.9.0esr | Released April 1, 2025. It is very simple to reproduce: 1. Start TB. 2. TB downloads new messages and continues to do it every 1 minute according to the setting. 3. In 10 to 20 minutes, it hangs. I have to force it to close and then restart it to check my email.

I believe it started to happen yesterday.

Is anyone else experiencing this?

I have a few favorite folders. One of them has sub-folders. Is there a way to favorite a folder and have the sub-folders be available at the same time? I don't want to favorite each sub-folder separately because the context would be lost. What I'm asking is there a way to show the "expand" option of favorite folder?

I have Thunderbird installed on windows 11 and have the import export NG tools add-on. I have an mobx file locally that I am trying to import to thunderbird. I created a local folder and started the import but almost immediately I get this error: "TypeError: window.ietngAddon.mboxCopyImport is not a function", and the only thing that gets imported is the name of the mbox file, as a subfolder

Hello, I am using Windows 11. I recently installed the latest update 24H2. Since a few days I have the issue that Thunderbird freeses after appr. 3 minutes of use. There is no crash report window popping up. I will be thankful to receive some kind of support. Thank you very much, Holger

Thunderbird stopped working and crashes at startup. It fails also in safemode. Any idea?

Hello--

I've been getting this notification error message for about 1 week now - every time I start Thunderbird (see attachment). I have no idea what this is, what needs to be done to correct it, nor where to go. Can anyone help? I thank you all for your time and help, and look forward to hearing from someone.

Thank you.....

Hello I have already reports these issues but did not receive constructive how to correct them. I'll try to be more precise this round.

Thunderbird Issues Summary:

• Received new messages in the inbox repeat in list multiples (not consistent)
• Messages deleted to trash repeat back into the inbox (sometimes also in multiples rounds)
• Notifications in settings non-functional (disappeared)/ Incoming email alerts popup and remain on my screen.

  (I have to manually close them one by one.)

• Mutliple unwanted sub-folders appear and reappear even after multiple attempts to delete them.

There are more issues but not as prominent as the above.

I use an old iMac. (See image)Us there there is an older TB I can download which is compatible with my system? IF it comes to that, HOW do I safeguard all my saved messages to move into the new version? Please advise. Thank you Rob

I am trying to import a backup of my gmail using using ImportExportTools.

What does this error message mean? Is there a corrupt email in my gmail? If so how can I find and delete it so I can complete the import, I think it was close to finishing.

2nd question.... After clicking OK on the error message I can select the local folder it was importing and I can see it is then downloading a range of messages with mention of their labels in the bottom of the window but the labels are not creating folders. Should I expect it to do that?
