I currently use Thunderbird and have for many years. I've had the same e-mail provider for just as many years, but they are going out of business Dec. 01,2024. I have opened an Outlook account, and synced it with my current e-mail, but cannot access my files in Thunderbird. MANY important files. Can I simply switch my provider to Thunderbird when my current e-mail provider closes? I would much rather continue to use T-Bird as I have been. I am also synched to my G-Mail in Outlook, but prefer to use the Outlook.com e-mail in Thunderbird. Thanks for your time and assistance. safeharbor@lighthouse.net

I tried all the suggestions online. I uninstalled, restarted my computer and re-installed but it just picked up where it left off including the pop3 email showing in troubleshooting mode which was an accident and I was receiving an error on so I selected not to check emails for it. The addresses WERE appearing at first, but now they have all gone away. I believe there was an update.

What are these new columns which suddenly appeared? From (CB), Recipient (CB), and Correspondents (CB)

I've never used them and can't imagine allowing them to clog my message headings so I uncheck them when I find them.

Hi I am syncing contacts between iCloud and Thunderbird and in most aspects it’s flawless. However when I change or create a contact in Thunderbird there seem to be a problem in character encoding. When I view the contact in iCloud the swedish characters åäö are replaced with som random strings. The other way around works as it should.

Does anyone recognize the problem and perhaps have a solution? Thanks.

I am unable to send any messages. Getting this error message - An error occurred while sending mail. The mail server responded: Resources restricted from 69.115.218.69 - try again later (AA,31).

It will list whatever address I am sending to or one off of a group. If I delete the one address it lists out of a group I get the same message with a new address cited.

Any suggestions?

While cleaning up email to get rid of the large amount of junk I sort by correspondent. This allows me to select several of the mostly junk emails together to delete them. I highlight the first email I want to delete, go to the last one and hit shift and click. Sometimes that can be over a hundred or so emails to delete at once. After selecting delete, sometimes they don't all delete. The email is no longer bolded as though I had read it, but only a portion of the selected actually delete. It sometimes takes 2, 3 or more times of selecting them to get them to all delete. This has just been recently, within the past few months that I have noticed this. Not a terrible problem, but curious as to why this happens.

hello, My gmail account disconnected and I cannot log back in. A window opens when I try to load my mesages, but an error occurs everytime. Do you know where it comes from ? Screenshots down below thanks !

Starting about a year or more ago, when trying to set up profiles on Thunderbird for a comcast.net email address, it would fail. The different errors generated would indicate it was a problem on the mail server, and not with thunderbird. Even comcast support couldn’t figure it out. With trial and error, I finally did. - Enter your name, address and password in the setup screens and allow it to get to the “configuration found” menu. - Select to configure manually. - Under incoming server for IMAP, Authentication Method will show 0Auth2. Change it to normal password. - For Username, it will be set to the entire email address. Remove the “@” sign and everything to the right of the “@” sign. So instead of email@domain.com it will show “email” and that’s it. - Under outgoing server for SMTP the authentication method will show 0Auth2. Change it to normal password. - If username shows the entire email address, (It shouldn’t, if you changed it for IMAP) then remove the “@” sign and everything to the right of the “@” sign. - Click the Re-Test button and it should pass. - Click the Done button and the setup should be completed with no issues. -

I had been happily using Tbird for many years. In mid February, when I tried to open my inbox, the message was "inbox in use for some other operation". If it was in use, I did not know about it. Then the message changed to "Thunderbird has crashed". I tried again many times over a few months but got the same results. I've just about been coping using webmail but with much grinding of teeth. Today when I tried again, there was no message and no inbox. I've also tried opening a 2nd Tbird account but got nowhere. Does anyone have any suggestions please? Thanks, Richard>

Ive recently started using Thunderbird and its setup with my Gmail account.

When i try and search from the search bar, on outlook i used to be able to search within the PDF document so if i had alot of invoices with the same product on it say 'TBA123' as the product code it would bring all the documents with that in the PDF, is this something that should work on Thunderbird?

Hi folks!

When I connect my Feedly RSS to Thunderbird's RSS subscription, I can't receive any new messages. In addition, I can't see the old messages in the folders. I couldn't find any way to solve this problem (for those who use Feedly).

When adding an RSS Feed, I don't get any valid URLs, I add it via Feedly "Organize Feeds ---> OPML Export ---> Download Export file" and then via Thunderbird "Feed subscripts ---> Import ---> My OPML file".

Thunderbird correctly reads all RSS feed URLs, file names, folder contents when I add this file. I save it and thinking it works and everything is fine. However, when I click "Get new Messages", no messages come through. I check the Feedly website a few minutes later to see if there are any new messages and I can see the new messages in Feedly.

In order to solve the problem and make it more understandable screenshots are below.

Thank you for your help, best!

Dear Support,

I am experiencing an issue with my PEC mailbox configured in Thunderbird. In the sender column, an incorrect email address often appears, unrelated to the actual sender of the received email. In some cases, I see the phrase "on behalf of:" followed by an email address that has no connection to the message in question.

This issue makes it difficult to correctly identify the real sender of emails. I have already checked my account configuration and updated Thunderbird to the latest version, but the problem persists.

Could you please provide guidance on how to resolve this behavior?

I am available to provide further details or screenshots of the issue if needed.

Thank you in advance for your assistance.

modzilla email error on ubuntu: The Local Directory path "/home/peter/.thunderbird/n4rpxwpa.default-esr/modzilla mail client error: Mail/pop3.wa.exemail.com-1.au" is invalid. Please pick a different directory.

TB stopped downloading emails from the Yahoo server. I still could send emails. I moved all emails from all TB folders (Inbox, trash, etc) to Local folders, deleted the profile. Redid the profile. Now TB still doesn't download emails. I get the message "The account xxxx@verizon.net is being processed. Please wait until processing is complete to get messages." AND now I can't send emails either.

Unable to send emails from my Laptop. Drop down box says "Outgoing server (SMTP) failed. I have compared settings on PC and are the same as the laptop. Have contacted my server provider and that is all ok. Can send emails from Optus webmail, but not from Thunderbird. Can send emails from the PC and that has Thunderbird also.

In Windows 11, the Address Book is accessed via an icon on top left of the TB main page or Alt+2. In Windows 11 is there a similar key combination to view the folders below Local Folders?
