On 9/10/24, I tried to download my email and got the message: "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox." To my knowledge, nothing had changed on my Win 10 computer, so why this is suddenly showing up is unclear. I have 555 GB of free space on my C: drive, so space isn't an issue. I don't know why the permissions would have changed.

I checked the TB help and found that there was an update, so I installed that. I checked for updates a second time and found another one which I applied too. TB is now at "128.2.0esr (32-bit)" according to Help > About.

I tried restarting TB in troubleshooting mode, but that didn't help. Can someone suggest a way out of this?

Thanks in advance.

I can't add an account. When I try to add an account, I get an error message: can't access property "cleanup", this[#configVerifier] is undefined The version of Thunderbird is 140.0.1esr (64-bit).

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.

Greetings! I downloaded Thunderbird for my new Win11 desktop, but it gave me an ESR version 128.9.1. It's working fine, but can i just move to the current 137.0.1 version? If so, how do I do that - just grab the current version and install on top of the ESR or should I remove the ESR first? Thanks in advance!

My Sent folder disappeared. How do I restore the folder with the sent messages still intact. Or, at the least, just restore an empty Sent folder. The In-Box, Drafts, and Trash are still there.

All the settings are correct, and it seems that because there's no Sent folder I cannot send an email. When I try to send a message I get the attached Error.

My local phone company routes email through Yahoo Mail, then to Thunderbird. It was all working fine until my Sent folder disappeared. Now because of the missing Sent folder I have to create the email message in Thunderbird saving it in Drafts so I have a record. Then, I have to copy it and send it from Yahoo Mail. Needless to say this is a pain in the you know what.

Can someone please provide the instructions to get my Sent folder back?

Thanks,

Tess

Taskbar icon does not indicate when new mail has arrived. Does not show a count of new/unread messages. 128.3.2 Windows 11

In settings "incoming mail" icon options I have chosen "show count of new emails" and "show a tray icon for unread messages is checked".

I am unable to tell at a glance if new email has arrived. I see from researching the KB I'm not the only to have this issue, but none of the settings seem to help.

Hi,

I need help on topic "Outlook, PST, EML and local folders".

I have .. - Win 10, 64 bit - Outlook 2010 - current thunderbird, first time installed 10 days ago (newbie!) - a huge, locally stored PST file with a lot of folders, like "in_2014 / In_2015 / .. / Out_2014 / Out_2015"

I want .. - to have access to the mails in the PST with Thunderbird.

I did .. - read some information and found that there is no direct access - install ImportExportTools NG - tried to import "Via Outlook", but failed: "No profile found". I think Outlook 2010 is too old - install "Outlook Viewer" from CoolUtils. Opened the PST, exported a lot of EML-files, one for every single mail. - defined a "Local folder", called "in_2014" - copied the EMLs to this folder. They appear in the folder-tree of Thunderbird, but not as single "mails". I have to open (doubleclick) every EML to see the mail. - tried to "Import" the data (one by one / many together / from folder) to the local folder, but got a long error message with a lot a strange error-codes - tried to export data from PST to one single EML with many mails in it. Failed, the software does not offer this feature. - tried to "Import" the EML to a folder of a mail account. This was successful, but only the first step. - tried to move / copy the currently imported mails from mail-account to my local folder: failed again without reaction and without message.

What can I do now? How to get mails from a PST to a locally stored, Thunderbird readable structure?

Thanks in advance for help.

Hello, I have enabled the Thunderbird dark mode. My expectation was that all messages in the message list are displayed in white on a dark background.

Unfortunately, the message list often uses a black font on a dark background.

I changed the color in the message pane using settings --> Colour

I followed the instructions/workarounds here for using dark theme, including reset and troubleshoot mode. https://support.mozilla.org/sv/questions/1439922

But it did not help. Maybe you guys can help.

Regards George

I'm using Version 128.6.0esr in Windows, but can't do drag and drop file for attachment at all. Previously it still can use this feature but suddenly it came to a stop.

The icon Ø will appear when we are trying to drag and drop a file to the create message window.

We already have tried the troubleshoot with no result.

Any advice on how to repair this?

Thanks

Typically if I experience a security certificate exception, thunderbird will popup the certificate exception box, I click to get certificate and am done.

Today I cannot get the certificate popup to appear. which is fine I know where the certificates are managed but I have not a clue how to add a certificate OR what information to enter into the "Add security exception" dialogue box

Any help would be greatly appreciated.

Hello everyone

I recently upgraded from TB 69 to the latest TB (after a crucial add-on finally got updated), and I'm generally happy with it, except for one little irk:

In Classic layout, the preview pane now contain multiple messages. As far as I can tell, it contains all messages of the selected thread, in date order (not in message list order). I would prefer the preview pane to contain just ONE message, namely the currently selected message. It is annoying to have to click repeatedly inside the preview pane to access the individual messages in the preview pane. It is also visually confusing (to me).

What's worse, the messages in the preview pane do not follow the normal threading: they appear to be shown in order of date, not in the order of the messages in the message list.

In the screenshot, you can see the thread has 11 messages, and in the message list there are three subthreads. The preview pane also shows the 11 messages, but not in the same order as in the message list. Plus, in order for me to read any messages, I need to click inside the preview pane to fold each message in or out.

I prefer a situation where I can click a single message in the message list, and a single message is shown in the preview pane. Is this possible with the latest TB?

Thanks.

Good morning, I had asked a question early on Saturday, but was unavailable the rest of the weekend so just now responding to associate Corey Bryan's answer. I had gotten a message that I am using an unsupported version and they recommend downloading the latest stable version.

He said it appears that I'm on the "Release" channel and most likely want to be on the ESR channel. I also mentioned that I am a cave-man when it comes to anything computer and am very skittish about making any changes as I don't how to straighten out any errors that might occur.

He asked me where I installed Thunderbird from and the answer is that I don't know. It was an IT guy that did it many years ago.

So I guess my questions are, if I've been using this version for years, do I need to or should I update it? If so, if I click on the latest stable version of Thunderbird, will that change anything on my computer, aside from getting the newer version of T-Bird? And will my e-mails in Thunderbird look any different?

Thanks very much for the help. Tony

I FOUND no close TOPIC.

Google calendar allows color-coding of events - but the display is highly inadequate. T-bird 128 calendar apparently HAS no option to color events. But events are FAR easier to see WHEN color-highlighted. Would this be a difficult option??

Hello, My thunderbird is displaying the following message when I forward an email. "An error occurred while sending the mail. the server responded the "name file.eml" attachment has been dissallowed extension". This error also occurs if the message you forward does not have attachments. my account is configured with pop. How can i solve the problem .

thanks

Have a folder on my yahoo webmail account with >100K emails accumulated over time. The emails are of no lasting value

I just received a notification (via a banner on yahoo webmail when I log in) that my storage is full (never seen this before, but not surprised that Yahoo would be looking for "additional storage" revenue - not interested.)

I'm attempting to delete the emails in this (large) folder (which are of no lasting value), so far with no success.

The initial problem is that yahoo's functions to expunge (permanently remove) the emails (after moving them to their trash folder) does not work (either 0% progress overnight, or progressing 0-100% progress, in either case all of the emails remain in their trash folder and I continue to be notified (by the banner at sign-in) that email storage is full (and I do not wish to purchase any additional storage from yahoo.) As this is a non-premium yahoo account, no support exists.

It appears that yahoo webmail does not expose their trash folder via imap (it appears empty on imap view). Thunderbird "empty trash" on the hosted Trash folder shows no contents and completes immediately with "emptied trash".

I've now tried moving emails from yahoo's trash folder to another (new) folder on yahoo webmail, then using thunderbird imap to move those emails from yahoo to a local folder. My expectation was that "move" means gone from server, present on client. That appears not to be the case.

While this step does create a local copy, a copy appears to be left in yahoo's trash folder which still cannot be removed, so the core problem (of their impact on yahoo webmail storage) is unresolved.

I understand that "expunge" exists in IMAP but I don't see how this can be used with Thunderbird.

As I'm somewhat going in circles trying to solve this problem, I'm reaching out here for advice.

Thanks

I have a problem with creating a new message. The "new message" icon or the keyboard shortcut from Windows does not work. The problem was in version 133, today's update 134 did not fix it. I have to edit an old created message/email and send it.

Others have mentioned this but I'm not sure if there is a fix/anything is being done. The threads are all from previous Thunderbird versions.

I use Thunderbird for work. I have to find specific emails and folders - get to them quick. I am no longer able to do this. It's really distressing.

This is something really basic, that should be the default or else really easy to change.

I'm on a Windows machine and using Thunderbird 140.3.0esr. I've been using Thunderbird since 2003 and never had any problems. Now I'm panicking!

When I upgraded my ubuntu system from 22.04 to 24.04, I was compelled to accept the conversion of thunderbird to snaps. Now none of the applications -- like http handler -- will run because snap maps them all to something under /run/usr/... AND THEY WON'T RUN FROM THERE I cannot even use Help to make a donation! I need to be able to get to vivaldi, firefox, libreoffice and others. Every time I enter one in the application box, the snapper remaps to /run/user/... I try to find that location and it's not there -- of course it won't run! -- and the application won't work. screenshots attached

Tell me how to roll back from v128.3.1esr to a version without snaps -- without losing 10 years worth of email!

Greetings to all, I'm trying to install the Thunderbird email client on a Mac that is running High Sierra. I have downloaded the installation package 3 times from the Thunderbird.net website but each time I try to open one of the .dmg packages I get an error that states the image is corrupt and cannot be opened. Is there something I'm doing wrong?

Hello, I'm using the most recent version of Thunderbird on a desktop using Windows 11. Just this morning (Aug 11), all incoming email to all my four accounts are coming in with no subject or correspondents showing and when opened the email is not formatted in HTML, just plain text and lots of code. I have tried several fixes with no success: repair folders, turn off all add-ons and anti-virus protection, uninstalled and reinstalled software. Can you help, please? Thanks!
