Thunderbird Community Forum

I just purchased a new PC. HP OmniDesk Slim model with Intel Core 13, Win 11 home version, 8 GB DDR5, 512 GB SSD. I just read a previous article, "Move Thunderbird data to a new computer." When you make the move, does it also bring your account settings with the move? And by the move, I mean copying and pasting from old PC to new PC. Or do I enter this info manually? I am moving data from old HP w/win 10 originally installed, to new HP w/win 11. I also read a previous article on forum, "An alternative method for manual transfer between Windows 10 and Windows 11 computers." This was also included in this article. "This section assumes you have a default Windows installation and will work on computers upgraded to Windows 10 from previous Windows versions." My old computer had win 10 originally installed, not upgraded, (as stated above). Any info/help you can offer will be deeply appreciated. Thanks

Hello everyone. From time to time, the "Attachments" button stops working. It can be clicked, but nothing happens. Occasionally, restarting the PC or the email client helps. More often, the only solution is to reinstall the entire program—which also means losing access to years' worth of emails, as I then have to wait for them to be re-downloaded from the IMAP server. What should I do? I’m using the latest versions.

I have a proper profile stored in an backup and 1 *.msf wasn´t restored on the new computer, but it is needed as soon as possible. My tries to restore it wasn´t successfull, there are no needed things to restore. The needed msf is located in the new profile, and I can´t see the item. Therefore I need help for restoring this particular *.msf. Greets The Texman aka K.-P. Aldag

Hello, I recently converted a very large OLM (Legacy Outlook on Mac) to Thunderbird on my Macbook. I added an Office365 (work) Account to Thunderbird, and the Outlook Addon App for Thunderbird. I can receive emails to the Office365 account no problem, but cannot Send emails from the Thunderbird (Host) Office365 email, unless I select the Default Outgoing Server which is a different email. I have reset Passwords, related Server settings, and Account Config settings numerous times.

The only other option is to send from the Outlook Addon App ,,, this works fine, But I cannot access the Thunderbird Local Folders from the Outlook Addon.

Any assistance with this issue is truly appreciated. TD

Recently I updated Thunderbird. When it rebooted, all my emails in the INBOX and ARCHIVED folders were gone. I have tried the usual solutions, including REPAIR FOLDER buttons. Those archived messages were important. Any chance of finding them?

I use Thunderbird with a info@... account hosted by TransIP.

When I send an email, especially when I reply to a previous email and even more when this was my own email, the sent email is not always saved in the Sent folder: neither in the webmail of TransIP nor in Thunderbird. It seems random when emails are and are not saved in the Sent folder.

The replies are sent through; the recipient receives them.

What can I do?

Despite my attempts to find an error in my outbound mail settings, I keep getting the message below.

The test of the connection to the server passes everytime, but the mail form will not allow mail to be sent.

It's the ESR version. It all started when I added a vcard to my outbound mail.

"Sending of the message failed. An error occurred while sending mail. The mail server responded: Sender refused. Please verify that your email address is correct in your account settings and try again."

I am trying to replace my Outlook account which has been blocked by Microsoft AI and remains blocked after multiple attempts to get it working again. I have just added a new account and can send @mail.uk e-mail from Thunderbird. However, there is only an in-box folder shown on Thunderbird and no trace of the sent e-mail - although I can confirm that is was received by two test recipients. I did consider a Thunderbird e-mail account as a replacement but, at 79, I avoid additional costs whenever possible. Can you suggest an alternative free e-mail service which works on Thunderbird? My g-mail account used to work but now I am having password problems.

A week ago my sent emails were being rejected and the error message included something about bluehost (I called them and it was fixed within the day). Now it's happening again and my error message says:

host eig-east.smtp.a.cloudfilter.net [3.228.35.199]

   SMTP error from remote mail server after end of data:
   550 Connection Rejected - see http://www.spamhaus.org/query/ip/162.241.218.139 AUP#BL
