Thunderbird creates a draft of every email sent and stores it in the Draft folder. There should only be 1 draft for every email sent, and, it should be removed when the original email is sent. It seems that a draft is created every time I pause editing to look at something else on my Laptop. I get multiple drafts and they are never removed.

I am on Windows 11. Thunderbird ver: 148.0 (64-bit) Is there a setting I can change to make the draft work correctly?

I have 2 email accounts. One is a Yahoo.com address and the other is an AT&T.net address. I have always been able to access both email accounts in my Thunderbird application on my computer (Windows 11). All Yahoo emails have always gone to my Yahoo mailbox and all AT&T emails go to my AT&T mailbox on Thunderbird. However, something happened this morning (a Yahoo popup popped up when I clicked on Thunderbird and I stupidly clicked on accept) and now I'm getting duplicate emails in both accounts. After I clicked on accept on the Yahoo popup, all my emails from all folders (inbox, trash, spam) from the AT&T server downloaded into my Yahoo mailbox (in Thunderbird) and were deleted from my AT&T server from myyahoo.com (not on Thunderbird). Is there anyway to reverse this or change something in the Thunderbird application so I can go back to what it was previously (all Yahoo mail goes to my Yahoo.com mailbox and all AT&T mail goes to my AT&T.net mailbox in Thunderbird)?

I have contacted Yahoo and AT&T about this and after spending most of the day on the phone with each of them, they informed me that since my mail provider (Thunderbird) is a third party application, I would have to contact Thunderbird.

Please help!

Hi,

I need some help! Thunderbird used to have archive settings in which I could choose to save my e-mails locally in my archive folders with 1 file per 1 email and not everything that's in a folder saved to a single file.

How can I get this back? Is there some hidden settings that can be accessed to get it done?

I need every email in one file! I'm going nuts trying to sort years of e-mail duplicates. If I can have a file per message, then I can at least use my PC duplicate file program to compare file content and find the similar ones. But with everything of one folder in the same archive file I'll be cursed to have to manually go through thousands of e-mails by hand! So if there is a way to return the previous archive format (*wdseml files??, it seems?) then I want to know how to set that setting.

Alternatively a local folder duplicate e-mail cleaning tool? There used to be some but I couldn't get it to work now!

I forwarded an email from a different email client to my Thunderbird email client and when I opened that email the left margin was gone. I tried selecting the text and clicking on the right index and nothing happened.

This type thing has happened before when I forward something that comes to my TB account, but usually highlighting the text I add, and clicking on the right index, will move it over a bit.

I would like to know why this is happening, and if I can prevent it or solve it when it does. It looks so unprofessional and sloppy when there is no left margin.

Thanks, NM

We tried installing Thunderbird on two PCs, both running Windows 11, but with unsatisfactory results. In July 2025, we bought a 15-inch HP PC running Windows 11. Thunderbird was installed, and the sending and receiving functions worked correctly with one domain name and three email addresses linked to that domain name. In January 2026, we bought a Lenovo T14 PC running Windows 11. We tried installing Thunderbird with the same domain name and three different email addresses linked to that domain name. Result: On the T14, it was impossible to install the third email address; only two addresses could receive and send messages correctly. Furthermore, the 15-inch HP PC now receives messages but can no longer send them; the connection is rejected by the server. Analysis: Apparently, there is an inability to coordinate the two PCs for Thunderbird. Question: Windows 11 had numerous updates between July 2025 and January 2026. Do both PCs need to have Thunderbird installed the same version of Windows 11 ?

Здрасьте дорогие разработчики

у вас есть функция, split-screen. Это круто! сделайте, пожалуйста, чтобы это могло включаться через контекстное меню(правая кнопка мышки), чтобы я навел мышку на ссылку и в контекстной меню выбрал этот пункт. чтобы я не через вкладки это делал, а через контекстное меню.

(EN) Questions and suggestions

Hello, dear developers.

You have a split-screen feature. That's awesome! Please make it accessible through the context menu (right-click), so I can hover over a link and select it from the context menu. So I can do it through the context menu instead of through tabs.

I made a folder and saved emails in that folder. A few days later they were all gone, empty folder. I followed suggestions on here, did the repair, erased password and replaced it, did the subscribe, and now even the folder is gone. I spent hours trying to research this and repair it and now I have nothing.

Greetings all

I have been experiencing a strange issue with Thunderbird for the last three months, and it’s quite frustrating.

I use an IMAP/SMTP SSL setup (ports 993/465) with a local server that includes webmail but also supports IMAP and SMTP for email client management. Over the past three years, we never encountered any issues, but since upgrading Thunderbird, this problem has started occurring.

As you can see in the GIF, messages appear and disappear when I switch to another folder and then return. This affects not only the message counter but also the actual messages themselves. At first, I thought it might be an indexing issue, so I tried deleting the *.msf files and the global-messages-db.sqlite file within the account profile, but the result was always the same. I also increased the frequency of checking for new messages to every 10 minutes and changed the maximum number of server connections to cache from 1 to 20, but nothing changed.

No issues with webmail and with other email client.

Do you have any ideas or suggestions?

Anybody else having issues with this feature? It had been working well to send tabs from my tablet and phone to my desktop computer, which I have been doing due to the lame way that FF uses for filing bookmarks into folders on the mobile devices.

A few days ago I started seeing "unable to send" popping up after a delay, instead of "tab sent" which typically appears immediately. Sometimes, the tab is sent even though it says it wasn't and sometimes it will send it after repeated attempts, and other times it doesn't. My wireless network and ISP connection are high speed and reliable.

So far, the problem only appears when trying to send from mobile to desktop. Sending from the desktop to mobile seems to work fine. The problem started while using 147.0.4 and persists after upgrading to 148.

I can receive mail fine. Cannot send mail on gmx.co.uk acct, but gmx.net works on oauth2. But oauth2 is missing on gmx.co.uk It's just not on the pulldown. I tried a new thunderbird acct for gmx.co.uk but oauth2 is still missing.

My 140 version of Thunderbird froze and I removed it and downloaded 140 afresh but it will not run. I just get a white screen and the settings button will not respond.

Hello. I recently upgraded from my older MacBook Pro (now factory reset and sold) to a new MacBook Air. I use Thunderbird as my email client and I have many folders that live within my Local Folders. When I transferred all the data from the older Mac to the new Mac via iCloud, and set up my new mail account (IMAP), the folders did not download into the program. I've tried using Subscribe but none of my pre-existing folders show up. Any assistance would be much appreciated. Thanks.

I have for a while been getting popups that TBird is unable to write email to a mailbox.

'Unable to write the email to the mailbox. Make sure the email system allows you write privileges, and you have enough file space to copy the mailbox'.

I saw that at least one other person reported this, and the suggestions included:

1. Rebooting. Done, no effect. 2. Antivirus interference. I am using standard Windows antivirus. Have been using same for years without issue.

The problem does not appear to interfere with writing to mailboxes. Seems to be an erroneous popup only.

I'm running FF v147.2.1 on my iPhone. There is NO translation option in the address bar OR in settings. It was supposed to be introduced in v146. Why is it not available despite having a version that is supposed to have the feature?

I have used Thunderbird for many years and and have loved it. However, recently my "Local Folders Inbox" have been extremely slow (deleting emails, reviewing an email, etc.). I have tried every suggestion that I have found without any change: reducing emails in the folder (down to about 75 remaining), compacting and repairing the folder, deleting and rebuilding all of the msf files and global database, disabling all addons, empty trash and junk, clear the cache, disable hardware acceleration, exclusion in antivirus, etc. It has become very frustrating. Any suggestions would be greatly appreciated.
