get this message every time I try to send an email:

Sending of the message failed. An error occurred while sending mail. The mail server responded: [VO-1] Message blocked due to spam content in the message.. Please check the message and try again.

I attempted all troubleshooting through the website to no avail.

When I used to empty Junk (and compact) & Trash, I would then File / Compact Folders that would show how much space I was saving - I do not see how much space I am saving now for the past couple of months.

Did a Setting get changed ???

Calendar data is correct in preview, but incorrect when editing

The dates in the preview (when I move the mouse over the calendar entry) are always correct. However, they differ from the entry when I click on Edit.

But it works for me when I delete cache.sqlite. However, I then delete the newer entry (which is displayed correctly in the preview).

Any ideas? Where does the preview data come from? Obviously from a different source than the data displayed in the edit view?

For a short while now all my received emails have extended line spacing resulting in excessive white space. I've not knowingly done anything to cause this. Is this something I can put right and how do I go about it?

I recently moved from one email hosting company to a new one and in doing so Thunderbird (128.4.3esr (64-bit)) has become very corrupted. I attach a screen shot of the folders, which shows imap folders in local folders and the wrong order of email folders in imap. How can I resolve this please?

Hey There,

Hope everyone is doing great!

The body search feature is missing in my Thunderbird. Searching for any text that I know appears in a body also returns no results. How do I enable this?

Please let me know if it's a setting that prevents this option from showing up. ( Just a thought, if it is some setting, could it be grayed out instead with a tool tip text to show why it's grayed out instead of removing the option completely? )

Cheers, Tom

The print screen has only one option to 'Save to PDF' and I want to replace that to 'Print' I've checked the settings and everything for email in there except 'Print'. How do I get to a setting screen where I can make this change. I am old and not computer savvy so please give me every step so I can finally print attachments. Thank You

I'm using a X13 ThinkPad with 1920x1080 resolution on a 13'3 display with Linux (Arch) and XFCE desktop. For the best results I've increased the XFCE's DPI to 134 and fonts sizes to 10. It looks like the fonts of the size ~13 without DPI change. It's fine, and applications like Firefox like those settings.

In Thunderbird I've set the font size (interface) to 12 and in Settings the default font sizes for Latin and Other Writing Systems to 12 (both) and finally the interface font as well as plain text email and HTML e-mails without font sizes specified explicitly look natively and perfectly.

But there are some senders using clients that generate HTML e-mails and specify the font explicitly as 'font-size=12pt' in their body by default. The same as my 12 so everything should be fine. Unfortunately font in those e-mails is really HUUUUGE! I'm wondering if there is some setting that allows custom scaling but only the HTML messages. Or some pt to px custom scaling for HTML? Or some maximal size allowed in HTML?

Good afternoon.

I will describe the problem step by step. There is a mail server. It has a web version of mail (SOGo). Created an account for the meeting room. Created a shared calendar and signed mail users with rights to create entries in this calendar. In mail clients connected calendars over the network with user credentials. When creating an event in the calendar, added participants. Participants receive an email with an invitation. Immediately, when the email arrives to the participant, there are buttons to accept, but as soon as the event is synchronised and added to the calendar, the buttons disappear. Why? An error occurs when clicking on the refresh button. Why? How to set up a shared calendar correctly? Is there any instruction?

I always find it useful. I have one problem. I usually only display [Attachments][Subject][Recipient][Date], but the default displays [Thread][Star], etc., and I have to edit them each time. Is it possible to create a [User default] by changing the settings? Thank you.

The theme keeps resetting randomly to "dark" - although it shows that the "light" theme is enabled - it still switches to "dark", i.e. the interface is the dark mode. I then have to Disable and Enable the Light Mode for it to be Light mode again. But, then even within a few minutes, while I might be doing something else - when I go to Thunderbird, it has switched to Dark mode again .... This is FRUSTRATING.

Bonjour. Thunderbird version 128.4.3esr (64 bits) - Windows 11 Professionnel 24H2 Build 26100.2314 Depuis quelques temps, les icones "Cardbook" et "Raccourci Google Task" apparaissent en double dans la barre d'espaces. L'activation/désactivation des 2 extensions ne changent rien. Avez-vous une explication ? Cordialement

All of a sudden there is no option to open a jpg. attachment with photo in windows 10. It just stopped working all of a sudden. Checked setting and all you can do is save it.

thanks

Hello Dear Thunderbird and Lightning Community!

Microsoft is removing their local Outlook calendar from Windows OS at the end of this year, and have already started to remove the direct to accessing it through their regular updates.

As I am looking for a local, reliable Calendar that would be on top of that open source, I found out Lightning as a further add-on/extension to Thunderbird.

Given the general context I have mentioned in the beginning, this is an historical opportunity for the open source community to raise Lightning as a major alternative to Outlook Calendar (and not only Thunderbird globally).

Why not offering Ligthning also, as a pure STANDALONE, local (with online calendar for people who wish it), but at east as a local possibility without NEEDING to instal Thunderbird as a whole?

That would make a lot of sense.

Thank you very much and great Kudos for all your great work!!!

Cheers :)

I use gmail IMAP server with Thunderbird. I "save" attachments to my local drive and the "delete" them. The intention is to save space on the server. While Thunderbird shows the attachment has been removed (a line across the file name followed by the size "0 bytes"), on the sever (login directly with browser) I see two copies of the email, one with attachment and a second without it.

Same behavior if I try to "detach", instead of "save" followed by "delete".

It does not change even after I compact the folder (Inbox), nor if I restart Thunderbird.

I have tried to check/uncheck Message Storage>Server Settings> Clean up ("Expunge") Inbox on Exit. No difference.

Is there a way to accomplish what I need? It seems Thunderbird creates a copy of the original email with the attachment removed, but doe snot delete the original (except that locally it is invisible??) Thanks.

Hello,

Recently I opened Thunderbird and it automatically added the following folders to my account:

https://www.imagebam.com/view/MEX6LYC

All the generic yellow folders below the Deleted trash can icon suddenly appeared and they weren't there or weren't shown before. I right-mouse clicked on the account folder, went to Subscribe, unticked the folders that I don't want to subscribe to (all the yellow ones were there), restarted Thunderbird and they all still appeared and the boxes I unchecked, had just rechecked themselves.

I don't want them shown. Is there anyway to fix this?

Thanks

Hi

Could we get a tool to lock folders in Thunderbird ? Or a warning before moving folders with drag and drop.

Pretty much what https://addons.thunderbird.net/en-us/thunderbird/addon/disable-draganddrop-tb-v2/ is probably doing - I'm just a bit worried to use addons that requires a permission: "Have full, unrestricted access to Thunderbird, and your computer"

I think this would be a welcome addition to many, especially those whom use IMAP like Gmail to use their mail account. If you accidentally drag a folder into another it can result a huge mess.

At the very least there should be an optional feature to get a warning message "Are you sure you wish to move this folder ..."

Thank you so much for this awesome software. I've used Firefox probably a few decades already .. and now Thunderbird too. Love it!

I'm looking for two features:

On minimizing window, thunderbird should minimize normally to taskbar as programs usually do. (This happens if the 'move it to tray' feature is disabled)

On closing the window, thunderbird should minimize as icon to the notification area tray. (This happens if the 'move it to tray' feature is enabled)

I think this should be an option integrated in thunderbird settings, if not to be the default behavior

i haven't found any extension to solve this yet and it is a little bit annoying when I use many windows and press alt-tab when thunderbird is minimized to the tray with x or - button when using the addon not to close thunderbird when pressing x, so it won't appear alongside other windows and i have to reclick the tray icon to show it again

I want to have both abilities to minimize to tray and minimize to TB at the same time

I believe that mail client has to be always running even if I press x button, unless I press Quit from inside the app

I have clarified the behavior expected above

Thanks
