I have saved relevant e mails to local folders in my Thunderbird account on my Applemac. I opened up Thunderbird on my MacBook and downloaded my Thunderbird account but it did not copy those local folders, merely 1 empty folder. Without these also shown in my Thunderbird account when I am away from home, I cannot see those records. I am struggling to find a solution. Are you able to help please? Alan Dowler

I was locked out from yahoo completely but managed to reconnect with their web client today but Thunderbird still doesn't work. my connection is POP with my ports set as: inbound.att.net 995 outbound.att.net 465 when I test the connection under settings in Thunderbird reports: Successfully established a secure connection to inbound.att.net:995. Successfully established a secure connection to outbound.att.net:465. I was at Version 146.0.1 so I upgraded to 148 with no difference

I get many emails as a member of a group, and often want to reply to the sender and CC the other recipients. Unfortunately it doesn’t seem possible to CC all, delete my email address from the list, and add the sender’s email in the Reply box. What is the best way to achieve the addressing I want.

I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

On my Linux machine, I exported the public key for an email address in Thunderbird 140.8.0esr (64-bit) into a file. I transferred the file to my Windows 11 machine via Warpinator.

On the Windows machine I am running Thunderbird 148.0.1 (64-bit). In Account settings>End-to-End encryption, I click Add Key>Import an existing OpenPGP key>Select File to import, and then I select the file.

I get an error message: Error! Failed to import file.

I'm surprised. I would think that going from one installation of Thunderbird to another would work this way. I am concerned that I won't be able to read incoming encrypted emails without the key working.

Can someone help me?

This is the only place I thought might match my request.

Well, maybe not so much support, but a request.

Any chance of adding a dedicated notes tab?

There are times I need to jot down ideas on an email, or quickly need to have data available readily.

DON'T want to have to open another application JUST to take down info.

Thank you for a great product.

About 140.8 ESR. Use the internal spam filter or externals like Bogofilter or SpamAssasain? 2nd: RSS option (Blogs and Feeds) every so often downloads duplicate feeds - how to remove duplicates?? Last: Earlier versions Thunderbird can import Outlook Templates - anyone knows how??? Example: I want to send my mom a Mother's Day email with a nice background but the background does not have to be animated - how would I go about that? I have plenty of email templates from Outlook 95/XP - just not sure how to import and use.

I am looking of the name of a address book I added. I know the\at the main book is called abook.sqlite. I have other sqlite files called abook-1.sqlite, abook-2.sqlite and abook-3.sqlite. What are these file contain? Also where are the other info like "Notes" stored? Are they also in the abook.sqlite file. I am using a DB browser and i don't see that info in the file.

Bei Absenden der email (wilhelm-wisch@t-online.de) folgende Fehlermeldung: "Senden der Nachricht fehlgeschlagen. Fehler beim Senden der Nachricht, SMTP-Server Fehler. Der Mail-Server antwortete: IP=38.246.32.196 - Your address is blocked.

Please help, thank you!

HI, Thunderbird for Mac no longer allows me to see emails more than 4 months old. I have an AOL account and when I use the (lousy) AOL app I can see email going back at least a decade, so I know they are there.

This changed with a recent TBird update. I have checked online support, studied the different settings, and cannot find out how to set TBird to let me access all my email.

Can someone help me with this?

Thank you, James

Thunderbird--All of my current year INBOX emails disappeared. I have tried repairing the folder, deleting INBOX.msf and restarting including in troubleshooting mode, reinstalled Thunderbird. None of these actions changed the situation. Is it possible to retrieve these messages?

The INBOX folder is much larger than the INBOX.msf folder, so I'm thinking the message info is in there?

I;m using Windows 10.

A few days ago I started getting a failed sign in for one of my emails. The solution seems to be that my authentication method in ≡ > Account Settings > Server Settings does not give OAuth2 as a choice. Screenshot shows what is available. All other email authentication methods have that as a choice. Is this a problem with the email program or T'bird? T'bird is 140.8.1esr (64-bit) O/S is Win11 Thanks for your help

Good morning . . . I have recently switched from an old Windows 10 machine to a new macmini, and have switched my Office 365 account over to it. Simply stated, Outlook is not working, and I have no desire to continue with it. Will Thunderbird suit my needs? Will it allow me to import my old contacts and emails, both from my Windows machine and the new MacOutlook?

Thunderbird version number: 148.0.1 Mail provider: Yahoo Client OS: Windows 10

The issue and steps I tried to resolve: On 1 Jan 2026 I switched from Outlook client on my Windows 10 PC to Thunderbird 146.0.1. I did not import any user data from Outlook but started with a clean install of TB for the new year. I use yahoo.com with POP3 as my email provider. Server Settings: Server Name "pop.mail.yahoo.com", port 995, SSL/TLS, OAuth2 Outgoing Server: Server Name "smtp.mail.yahoo.com", port 465, SSL/TLS, OAuth2

it all worked fine and I was very happy with the setup. Then from early to mid-February I was unable to use my computer. When I finally accessed Thunderbird again, it connected to Yahoo and showed that approximately 800 email messages would be downloaded and started downloading them. After downloading about 100 messages, Thunderbird timed out and I haven't been able to get it to work since.

I have read and followed or tried to follow these articles plus others that I may have forgotten about (not listed in any particular order) - OAuth2 Authentication for Yahoo, AOL and ATT | Thunderbird Help - including all the steps in Please check the following before asking for support - POP access settings and instructions for Yahoo Mail | Yahoo Help - Automatic Account Configuration | Thunderbird Help - Manual Account Configuration | Thunderbird Help - Thunderbird and Yahoo | Thunderbird Help - Send and receive messages in Thunderbird | Thunderbird Help - Can no longer get emails | Thunderbird Support Forum | Mozilla Support - Emails suddenly stopped downloading to Thunderbird 140.2.1esr | Thunderbird Support Forum - Get Messages | Thunderbird Support Forum | Mozilla Support - Cannot receive messages | Thunderbird Help - Problem with Thunderbird working with Yahoo Mail acccounts. | Thunderbird Support Forum

I have removed all messages from the Yahoo inbox and tried to find one or more messages that may be affecting the download. I don't know the best way to determine that.

I use Windows Defender for my antivirus. I don't see anything in Defender that blocks or scans email messages which would prevent downloads, although I could be wrong about that. if this might be the issue, please provide some guidance about how to check Defender.

I have uninstalled and re-installed Thunderbird. In the process I downloaded the setup file for Thunderbird Setup 148.0 and installed that version. It later auto-updated to 148.0.1. Before installation, I removed all external connections from my Yahoo account and completely removed Thunderbird from my PC, including the profile and profile.ini. When I reinstall and switch the account to POP3, Thunderbird captures the App password from Yahoo and connects just fine. But it still times out while attempting the first download of a message. The first several times it timed out, an error message was displayed but now it doesn't show anything. Except no messages are downloaded.

At this point, I don't know what else to try. Since I don't have much experience with Thunderbird, I don't know how to troubleshoot the process (logs to look at, etc.). I don't want to go back to Outlook but I need the email client to work and download messages. Any help would be much appreciated.

I am running Thunderbird 140.8.1esr on macOS Tahoe 26.3

I created an IMAP account in Thunderbird to replace a POP account

I want to copy the Thunderbird message filters from the POP account to the IMAP account

I read articles on Mozilla Support and these said to copy the msgFilterRules.dat file but I cannot find this file

How can I copy the message filters?
