I have had message filters set up for a long time. Recently I tried to make some changes (adding one filter, deleting others, changing the response). I find that if I close Thunderbird and reopen it, all my changes are gone! How can I get the filter changes to stick?

I have downloaded the addon cardbook. Now, how do i find my old address books that existed prior to the addon? Please do not leave a single step out on how to migrate back or forward or what ever i have to do to get my old tb moved to the new cardbook tb supernova. Thank you.

There are two "bad email" files in Thunderbird: JUNK and SPAM. I'm still not clear on the difference.

For JUNK mail, TB gives us the option to select "NOT JUNK". Good.

But for SPAM, I cannot find the option "NOT SPAM"

1) Why are there separate SPAM and JUNK directories? And why are they managed differently? This seems terribly non-intuitive and inconsistent and just strange.

2) How can I train SPAM filter to not flag good email from trusted senders? For instance, I get email from my wife many times a day for many years. Today, TB put her email into SPAM. Isn't there a simple command to "white list" a sender's email address?

Upgraded to Sonoma 14.5 on iMac and when trying to open Thunderbird, I get the message "Thunderbird" is damaged and can't be opened. You should move it to the Trash. What do I do?

How can I have the original mails deleted from original Gmail inbox when deleting them from unified inbox.

I am reading my mails in a unified inbox - and deleted some read and unwanted ones. Now I am looking at my Gmail via my iphone's mail app - and none of those emails have been deleted... How do I get those deletions to sync back to my Gmail account?

Thank a lot!

I am moving Thunderbird to a new PC, old was Win 10, new is Win 11. I installed Thunderbird on the new one, same version 115.10.2 though this is now 64 bit, old was 32 bit. I followed the instructions to move the profile by copying the Thunderbird folder onto aUSB stick then copying it to the new computer. The address book is there, but the local folders I had are not. Looking inFile explorer, I see that the Local Folders folder is there which contains all the folders I had, all populated, but there is also a Local Folders-1 there which does not, and this is the one Thunderbird is using. If I delete this folder, next time I start Thunderbird, it creates this folder again. I have obviously done something wrong, but cannot see what it is.

I'm unable to send any emails from account on Thunderbird. This just started this week. All send attempts generate this Send Message Error:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Please turn on SMTP Authentication in your mail client. syn-076-088-235-065.res.spectrum.com ([192.168.1.25]) [76.88.235.65]:51343 is not permitted to relay through this server without authentication.. Please check the message recipient

This error for every recipient I typically correspond with. I have my same email account loaded into Outlook on another pc and I can send emails to all recipients without error from Outlook.

Help please.

Hi,

I've been a Thunderbird user since the days of Eudora ;-) and have a configuration question.

When you forward or reply to a message, Thunderbird currently does this: <sender> wrote on <date> <time>:

  forwarded message text

Is there a way to change the preamble line, or is it hard-coded?

Thanks in advance for any pointers.

In the previous version, there was a search box on the toolbar. After the upgrade, it disappeared. How can I restore it?

I tried to customize toolbar but there is no search box in the window of available controls.

In the image mu mailbox shows the number of unread messages 234, the total number of message 1003 and the storage used 77.9 MB. I set tese options using a little button and then foolishly clicked another little button that hid the option to choose what to display. I am unable to turn that second button on again and so cannot comntrol the display of inbox usage. How do I turn that button back on? Thanks for any help.

115.05 when I started.

I typically open Thunderbird about once a month, download my emails from a hosted website, do some clean up, write some emails, close Thunderbird, and do the same about a month later.

Today I opened Thunderbird, saw that it was downloading around 400 emails in the lower left corner, and waited patiently, as per usual. When "done", however, none of them showed up in the main window. The latest email did not change, was still from around a month ago. When I ask Thunderbird to Get Messages it says there are no new emails to download.

I restarted Thunderbird several times, no change.

I then upgraded to 115.10, hoping this might fix the issue, but it has not.

Since restarting Thunderbird, 2 new emails have come in and are showing correctly, but none of the initial 400 emails "downloaded" today are showing anywhere.

I repaired the Inbox folder (right click > Properties > Repair Folder), no help. I renamed the "Inbox.msf" file and had Thunderbird rebuild it, no help. I renamed the "global-messages-db.sqlite" file and had Thunderbird rebuild it, no help. View Ignored Threads does not help. View > Threads > All is selected. Emails are not in the Trash folder, or any other folder.

All of the initial batch of 400 emails - and the emails I had previously opened - just disappeared.

Opening up the Inbox MBOX file directly, I can see that these 400 emails were never actually downloaded into this file. Not sure what happened.

Opening up my remote email host, I can see that those 400 emails are still there, to the exact point when I last closed Thunderbird.

Asking Thunderbird to download new messages does not download these remote emails.

How do I reset Thunderbird to start the process over and re-download these emails again? Part of TB seems to think it's already downloaded these emails, while another part of TB never actually did.

Does anyone have any idea what to do here?

Somebody thought that it is a GREAT idea to make drag-n-drop cursor a GIANT rectanglular thumbnail of the emails being dragged.

No, this is a horrible idea because that thumbnail covers the target of the drag-and-drop.

Either REVERT this IMMEDIATELY or let us know how to disable and revert to the simple drag-n-drop mouse cursor that does not obstruct the target of the drag.

And in the future AVOID any GUI changes that are not ABSOLUTELY NECESSARY. With these poorly thought through, extremely annoying changes you are only causing damage and aggravation.

Over the last few weeks, emails have vanished from my inbox, as well as trash, templates and other mail boxes. In may cases, no emails are being displayed, when "total message count" shows messages are present. In other cases, several days of recent messages have disappeared.

I have tried "repair folders," deleting "smart mailboxes' and even deleting the .mlf file of one inbox without success.

I have 6 email accounts including 2 GMail. The problem is in all of them. As the screenshot shows, there is a disparity between total messages and displayed messages in all boxes (partial view of accounts).

I am running Thunderbird 115.9.0 on Lubuntu 23.10. I have 4 IMAP accounts I use. The folder and file is not shared and I am the only account with access to the directory.

I use emoji as tags for messages, and have a large number of filter rules defined, nearly all of them Tag a message and set the Junk Status to `Not Junk`. These rules are all set to execute `Manually` or on `Getting New Mail`.

If I select a given inbox folder for a mailbox and select `Tools` > `Run Filters on Folder`, all of the messages are properly tagged, however, after some time (10m?, On new mail receipt?) at least one of my mailboxes will lose all of the tags that were previously set for messages. Manually running the filters will restore the tags, until they disappear again some time later.

I've not seen anything in the Browser Console log (but perhaps I'm not using the right term?) Is there any way I can diagnose or fix this issue? Thanks!

My environment - I am running Thunderbird 115.10.2 (64-bit), and Windows 10. - I have had NO Windows updates for at least two weeks.

The problem - About five days ago, outgoing messages (messages I was trying to send) started taking about 15 to 30 seconds before they were sent successfully.

- Today, I am unable to send messages. I can receive messages.

Actions I have taken 1. I re-installed Thunderbird after using Revo Uninstaller to uninstall it. 2. I contacted my ISP. They checked their settings, and have been unable to detect any error.

Please help!

When TB starts up, the only folders I can see are Recent. I can go to View/Folders and click ALL, and as soon as I move the mouse away from that menu item, it switches back to Recent. This started on version 115.09, but persists after I've "upgraded" to 115.10.1.

It has now (5/3/24 17:25 CDT) been 2-1/2 days since I submitted this problem, and no one has responded that it has even been noticed, much less solved. One of my two email accounts is a POP3, and the other is IMAP. The IMAP account Inbox doesn't even show up on the TB home screen. (If that info is of any help).

PLEASE ADVISE. My emails are an integral part of my business, and I cannot get to almost any them.

Thanks, rehawkpe

I just asked this question a few minutes ago. This is a correction. It's only the font size in my signature that has shrunk since the latest Thunderbird update. The image in the signature is still the same size as it was before the update. I would like to know HOW to make the signature font size the same as the message font size.

I just installed Thunderbird on a computer, current version, and it didn't update my address book or contact list off the server. How do I do this manually as I could not find something saying to "download contacts" or anything like that. There is the "Directory Server:" option but I don't know what that is or how to use it. I didn't do that on my other Thunderbird installation (Work Computer). My email server is Mail.com if that matters. Thanks

I've been running Thunderbird for years on Gentoo which has version 115.10.1 as the most recent. I don't send much mail so I'm not exactly sure when this problem occurred, but I'm unable to authenticate with my SMTP server. I have not changed any configuration. Some weeks ago a changed my password on the server, but I made the appropriate changes to Thunderbird password manager. All settings, username and passwords are 100% correct as I copy pasted all of them. IMAP on the same server (uses same credentials) works.

I have tried deleting and re-adding my accounts which did not help. I have also tried deleting my profile folder. All other mail clients (e.g. claws-mail, kmail, mailspring) with the same SMTP server don't have any problems sending mail. This problem seems to only affect Thunderbird and Thunderbird forks such as Betterbird.

I have no firewall and am using SSL authentication with cleartext password on the SMTP server.

I get the following output to console on attempted sending of message:

console.error: (new Error("Server error 503 Service Unavailable", "resource://services-settings/Utils.sys.mjs", 390)) console.error: mailnews.smtp: "Command failed: 535 Incorrect authentication data; currentAction=_actionAUTHComplete" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.send: "Sending failed; Unable to authenticate to Outgoing server (SMTP) mail.kapsi.fi.
