I keep getting error messages like below..... up to 50 a day where my Thunderbird is not syncing with my hotmail email. I can not force it but just wait until it happens to automatically sync. It keeps getting worse every week and I just got a notice from Microsoft that they will no longer accept third party programs that do not support modern authentication after September 16. I love my Thunderbird. What can I do to ensure access to my hotmail with Thunderbird?

I'd mistakenly said that the Inbox's other emails are hidden when I click the X on the tab of an open email; that was wrong; they disappear when I press Del when viewing the tab of an open email. Dave

Since you sent me an email asking if I have any questions, I'll try a third time with my question. Frequently, when I close an email--either by selecting it in the Inbox and then pressing Del, or by clicking the X on the tab of an open email, the remaining emails in the Inbox disappear for awhile (progress in re-displaying them is shown by thermometer at lower right). However if I click another folder, say Drafts, and then re-click the Inbox, all are instantly visible--except of course for the one I wanted deleted.

Any thoughts?

I moved some emails to a folder from the inbox and now they are not displaying. when I search them I am able to find them and can be read, the search indicates that they are in "the new folder" all mail and important. This has happened before and I have not been able to resolve I am assuming there must be a setting I have activated/deactivated but I've no idea what. I am FAR from tech savvy so please give any answers in as simplistic form as possible. Thanks Matt

Hi, I believe in the past I was able to read an email by clicking on it and it would appear on the left of the main page. However, now whenever I click an email it opens in a new tab. This makes reading them take considerably longer. Is there any way to switch back to having them appear on the side instead of opening a new window/tab?

cox migrated their email system to yahoo but i dont believe yahoo uses usernames anymore, just email addresses so i cant set up my email to thunderbird since it requires a username and like i said i dont think one exists anymore.

When checking email, Thunderbird's status bar at the bottom will report x number of emails received (e.g., "received 1 of 1 messages"). I have not had difficulty receiving email and those messages displaying in the Inbox--but there have been a number of instances where the status bar will report one or more messages have been received, but none display, despite the fact that I do not nor have I ever had filtering in place. Since I continue to receive emails that display when received, the only thing that concerns me is that there could be messages that are being lost, and I have no idea how to correct the problem and be assured that each and every email is retrieved and displayed. Thank you for your assistance.

Hello

I created an Archive directory within Local Folders, and within that have stored years of emails.

As of yesterday, when clicking on any given sub directory within the Archive, Thunderbird says that there are 0 messages to display.

All of the .sbd and .msf files are present when I browse the Archive structure in my user profile in Windows Explorer.

The problem seems to be that Thunderbird can read and display the directory structure, but cannot display the emails contained within it.

I do not have a backup of the profile directory (yes, I know!).

Can anyone offer a solution that will allow Thunderbird to display messages that seem still be present ?

With thanks in advance

have been using Thunderbird mail for about 3 years. It’s template selected the incoming and outgoing servers and ports etc..successfully. I've been connecting to Prodigy mail/ATT I had to change the battery and it doesn't work anymore. Can you help ???it checks the password until it shows an error message that the servers password or etc are wrong. I know the password is right since I can log in directly. Messages :

1- Configuration found in ISP Database

2- Checking Password (for a few minutes

3- Unable to log in at server..probably wrong configuration username or password

4 then nothing

Worked great before battery change

In Thunderbird, I would like to use Cards View, and sort each folder in my email account according to desired 'Sort by' settings (namely, sort by date in descending order and use the 'unthreaded' option).

I cannot locate a setting or an option to apply the desired sort settings to all folders in my account. Rather, it appears I must manually apply these settings to each folder, which is tedious given I have a large number of sub-folders in my inbox folder.

Is there a way to apply the settings for one folder to all others, or to change the default settings for each (existing) folder?

It has stopped working. Starting 2 weeks ago, Thunderbird keeps saying "Login to server imap.aol.com with username stuart_jones@verizon.net failed." I don't know what to do.

I'm migrating Thunderbird from my old Windows 10 computer to a new Windows 11 computer.

I've installed Thunderbird v115.12.2 and successfully moved all my accounts, emails, calendars, etc., to the new computer.

Several things are NOT working correctly, though:

1 - Settings will not open. Here is the message from the error console:

Error: No such tab mode: preferencesTab

   openTab chrome://messenger/content/tabmail.js:758
   openTab chrome://communicator/content/utilityOverlay.js:257
   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295
   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295
   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

2 - Customize menu does not open

3 - The hamburger menu in the upper right corner does not open

4 - The spaces toolbar on the far left is missing

5 - Events and Tasks are missing from the menu

6 - My calendar is nowhere to be found - I can't find a way to access it (on my old computer, I clicked on the calendar icon in the spaces toolbar on the left side of the window)

Thunderbird on my old computer was also running v115.12.2 when I backed up the profile folder to move it.

I tried downgrading to Thunderbird v102. I had all of the same issues listed above PLUS all my accounts and emails disappeared. -- I've brought it back up to v115.12.2.

Could someone please help me get Thunderbird working correctly?

My wife sent me an email with a small word file to my Yahoo and I see the email when I log into Yahoo but not Thunderbird. I have always been able to receive emails with attachments before so don't know what to do. I'd be fine if I saw the email without the attachment but no email shows up at all in Thunderbird, only Yahoo email.

I move old emails to archive folders, by year, when I get around to it. Today decided to shift emails from Sent file back to 2020, and from Inbox for all of 2022 and for the first half of 2023. Archived each year's batch separately. In every case I got a "Thunderbird not responding", so eventually stopped it via Task Manager. When I restarted, all the highlighted emails had been moved properly. When I did it for the first half of 2023, all the emails appeared as expected in the 2023 Archive folder ... for a few seconds. Then they all disappeared, as did much of the content of the other annual archive folders. What do I do to recover all those emails?

I'm a writer. In keeping with the Law of Primacy, my first work is usually my best work (after a few tweaks). I recently had to write an email response to someone for the Darling Bride and me.

I waxed poetic and wrote an incredibly diplomatic response to a most unpleasant situation. After completing the entire message down to our signatures, I selected "File" and "Save" to make sure it was all saved in the Drafts folder. That way, I could open it on another device and read the draft to her.

Imagine my shock when I opened it, only to find that the draft stopped in the middle of a word - while I was correcting a typo - and didn't save anything after that! Frantic, I went back to the computer I used to write it, hoping the entire email was at least saved locally. Nope! The draft stopped in the middle of the message, even though I had saved the entire thing.

Perhaps this isn't high priority for a lot of users... but for those few of us, it's a critical, fatal flaw that has to be resolved. I can't even imagine that I did anything wrong: I saved the message before exiting; and opened to find half of it missing. I love the idea of Thunderbird and its privacy features, compared with the data-mining big names. But I can't afford to lose data! This was a personal response, thankfully, and not related to my work as a writer and author. However, I have to trust my email client with the data I save to it. Any hints to prevent this are greatly appreciated.

I am having trouble manually configuring an AOL email account (username@verizon.net). AOL's instructions say to manually configure the account. I tried to do that twice, once with IMAP and the other with POP.

Now, I have two email folders in Thunderbird that I cannot use. They are both empty because I get a message box that says "Login to server imap.aol.com with username@verizon.net failed." when I try to use them. When I use the same login credentials to login to the website mail.aol.com, they work.

I have to contact AOL as to why when I try to access the account with an email client (Thunderbird and Outlook) I'm getting password errors. In the meantime, how do I delete the two email folders created incorrectly in Thunderbird?

Thanks for your help.

When I restart Mozilla Thunderbird, my S/MIME certificate preferences under Account Settings seem to break.

When I initially select a certificate, both the common name/certificate name and the certificate fingerprint appear in the interface (see Working Settings.png). However, after restarting Thunderbird, only the common name/certificate name appears in the interface, and I cannot use S/MIME to sign messages (see Broken Settings.png). When I attempt to do so, I receive the following error message:

Send Message Error Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired.

To be clear, Thunderbird has no problem finding and using the certificate right after I set it—the problem only appears when I restart Thunderbird and the appearance of the certificate in the settings changes. The certificate does not expire until April 2025, so this is not the issue. The issue also occurs with another account using a different certificate that is also unexpired.

I am using Thunderbird 115.12.2 (64-bit ESR) on MacOS with Apple Silicon.
