Thunderbird Support Forum

my email will go offline while in use or while other internet programs working fine and only allows "send later". sometimes comes back shortly other times can be hours later. How can I check status and bump it back online without having to shut down and lose work.

I have changed my BT password and now can't send emails via Thunderbird. I can send them with BT though. This is the answer I get when I try to send an email -

''Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.''

When I check my outgoing server settings I get this -

Description: BT Yahoo Server Name: mail.btinternet.com Port: 465 User Name: rvynerp@btinternet.com Authentication method: Normal password Connection Security: SSL/TLS

Can anyone help as I much prefer using Thunderbird for emails, over BT Richard P.

Hello! I have tried to install the normal Thunderbird on my PC for months now. Everytime all it does is count more and more files, folders etc. I can't get it to install. The two screenshots were made within a few minutes. I let it install for around an hour one time and it simply counted more and more files without ever moving in progress. I really don't know what to do. Restarts, redownloads, nothing works. Maybe someone knows what's wrong. Thanks!

Hi, just upgrade to Windows1 and did a new installation from Thunderbird. latest version 115.11.0 (32-bits) But the new messages are almost directly market as read even with setting mark messages automatic as read set to no? On a other pc with Windows11 I had the same problem with the 64bit version but going to the 32bit version solved the problem. Any Idea how to solved this problem? Regards Karina

I permanently deleted all messages in a folder (call it "Unwanted"), then moved Unwanted to Trash, then deleted it permanently. It appeared to be gone. However the next time I opened Thunderbird, Unwanted was back. I tried this several times with the same result. I tried renaming it to "DeleteMe" but then I got the message "The folder could not be renamed. Perhaps the folder is being reparsed, or the new name is not a valid folder name."

Once again, I "permanently" deleted Unwanted and closed Thunderbird. Using a file manager, I found and deleted all relevant folders and files matching "Trash.*" and "Unwanted*.*" and rebooted the computer. However when I opened Thunderbird, an empty "Trash" folder was regenerated as expected, but the "Unwanted" folder was back.

How can I get rid of Unwanted? Thanks!

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

I am using a Mac with Big Sur (macOS Monterey, Version 12.7.5), and my email is POP, using Thunderbird Version 115.11.0.The message count of my inbox is wrong. It is two (2) more than it actually is. Right now there are ten (10) messages in my inbox BUT the message count of my inbox says twelve (12). Please correct.

I am using a Mac with Big Sur (macOS Monterey, Version 12.7.5), and my email is POP, using Thunderbird Version 115.11.0. I first retrieve the mail header, then I click on "Download the rest of the message" if I wish to read the full message. When I click "Download the rest of the message" to see the contents of the actual message Thunderbird downloads the rest of the message, highlights the message (new) but then displays the next message in the list of messages in my inbox. The message I had wanted to read now becomes the previous message in the list in my inbox. I then have to go back and click on the message itself to see its contents. Please correct.

I changed my BT email password but cannot send emails from Thunderbird. I can receive them. I receive this message - Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'. I have checked my outgoing server settings which are -

Description: BT Yahoo Server Name: mail.btinternet.com Port: 465 User Name: rvynerp@btinternet.com Authentication method: Normal password Connection Security: SSL/TLS

My BT email works fine for both receiving and sending so the problem is with Thunderbird outgoing mail settings

I'm having problems with the Cardbook add-on but it is up to date based on my version of TB. When I go into Preferences->Advanced-> Update 'Check for Updates' shows I'm up to date. However, when I check archived versions it looks like the last version that worked with a MAC release of less than 10.12 is 78.14.0.

I'm confused if I can upgrade to 78.14 and how I would do it?

Thanks for any advice

P.S. and yes, it's a very old Macbook from 2009.

Good day,

I am encountering an issue with opening messages through the global search feature. Despite being able to locate the specific email, clicking on it does not display anything as depicted in Figure #2. I believe the email is stored in one of the folders.

I would greatly appreciate your guidance on how to properly open messages using the global search feature in order to reply based on the original correspondence.

Thank you. May

After making some alterations to google account to use phone for credit card use. I started my Thunderbird email client to deal with my mail. i received email as normal and was able to delete unrequired mail as required. However those I wanted to file and place copies in local boxes no longer worked. I instead go a notice saying sign in with Google failed 400 error.(cannot process request malformed)

I am posting this on my Mac Monterey; but the problem is on my Windows 10. It is similar to my last post about Firefox on that system. Updating is hanging. About Thunderbird shows an update available, just as that feature on Firefox did last week. However, though it indicates that it is attempting to download, it shows that nothing is downloading. So, there is a spinning icon on the left, but zero bytes downloading, just as Firefox did. After a restart last week Firefox applied the download. The same action occurs now with Thunderbird. To contrast, that same update just downloaded and applied on this Mac Monterey. The version on Windows 10 is 115.10.2, 64-Bit. There is a general Windows Update problem on that system. Edge, on the other hand, downloads its updates without any problem. I just ran a Troubleshooter that Windows makes available under Settings, Update and Security, Troubleshoot. Right now I am about to restart that computer.

Had all my emails stored locally. Accidentally uninstalled Thunderbird. Reinstalled. Unable to Import my old settings from my "profile". Error message says "Unexpected error" Was able to import configuration alone, but it was all wrong. Can't set up my gmail account. Error message "Malformed server" Please help

Thunderbird keeps suggesting to use the Filelink feature for sending large files. And I am quite on board with that idea. However, the only way I can officially share large files with the industry partner is a Kiteworks platform, that is configured to only allow SFTP and the webclient.

When clicking on "Find more providers", the only provider that isn't specific to a business like Dropbox is Webdav.

Is there any way to use an SFTP server for Filelink?

Hello,

I have a strange issue that i didnt find a solution for online. I have made a few new folder and message filters for them. I dont get number notification in taskbar for mails that go in the new folder while the notifications for mails that go in the inbox work just fine.

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.cp.co.id failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Since Thunderbird was upgraded to 115.10.1 (64-bit), it now fails to send SMTP messages with the following error.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) ***.mail.pairserver.com was lost in the middle of the transaction. Try again.

This affects all six(6) accounts in Thunderbird, all of them can receive and edit e-mail messages; however, all of them fail to send e-mail messages.

Prior versions of Thunderbird have worked with this configuration for many years.

Other e-mail clients such as Evolution do not have this issue and I have confirmed with my provider that Thunderbird is no longer sending e-mails.

Any thoughts on how to roll back Thunderbird until this issue is resolved?
