I changed my email password on the providers web site, my phone, tablet both asked for the new password but Thunderbird has not, why can I still send and receive email ?

And don't see a place to change the server password either, I thought it would just ask.

Hello,

Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.

Remembered this old message I got so I went through and deleted my second email address, didn't help.

https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo

Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.

Anyone have any ideas?

When I type the word "attachment" in version 149.0.2 I no longer get the warning bar across the bottom of the screen. I do have the "check for missing attachments" box checked in Settings.

I have relied heavily on the "Open message in conversation" function, because it gave me a tree of messages across all folders (Inbox, Sent, etc.) that was based on the person I was corresponding with.

Now, the function is giving me a tree based on the Subject of the message. This behavior makes it useless to me. I've looked, and I can't find any configuration setting that would control this option.

How can I once again get a message tree based on the correspondent's name, then sorted next by date?

Thanks!

Over the last week or so, selecting a link embedded within an incoming email on Thunderbird does not now ensure that the desired webpage will be opened in Safari and other browsers. Shutting down Thunderbird, intermittently enables the proper functional activity of opening the desired webpage. I've discussed this with Apple (iMac; Sequoia 15.7.5) and was unable to identify this as an Apple problem.

Have been using the 104.9.0esr 64-bit release on Windows 11 for some time now (mostly for email, involving a number of email accounts) and have been generally satisfied...

...but discovered when I started looking into switching over to the 145 default release that I have a capital-P Problem. The first thing recommended on making that change is - sensibly - to back up one's Thunderbird profile. Only as far as I can tell, I don't *have* any such file anywhere on my system. [To answer the obvious question - yes, I've got "View" set in File Explorer such that it should be showing me hidden files.]

I have drilled downward through all the USERS subdirectories on my C: drive. "Default" and "Public" have nothing at all (as one might expect). My personal subdirectory has a Mozilla directory under "Roaming", and both a Firefox and a Thunderbird directory therein, but the only things in the Thunderbird directory are an empty folder labeled "Crash Reports" and a tiny "desktop.ini" file.

There is a "Mozilla Firefox" directory under Program Files, but nothing in that hierarchy looks applicable. There is a "Mozilla Maintenance Service" directory under "Program Files (x86)", but nothing there appears relevant. There is a "Mozilla [alpahnumeric hash]" subdirectory under "Program Data", but nothing there appears relevant.

And in fact, I begin to think I have a bigger issue than I thought I did...because the more I poke at my C: drive, the less I'm seeing...to the extent that I'm not at all sure where the Thunderbird program itself (not to mention a quite large accumulation of associated email) is being kept.

Which would be nice to know if one were attempting to back up one's mail before changing program versions....

My email storage server has a limited space allocation. Because I keep most emails for future reference/recall, I have been moving important emails to specific folders I have created in LOCAL FOLDERS. The LOCAL FOLDERS resides in a local drive in my main desktop computer.

Lately I switched from POP to IMAP so I will be able to access my emails on my phone, remote desktop at home & on my notebook when I travel.

Because of limited storage space allocation, only the main basic folders (inbox, drafts, sent, junk, trash, etc........) reside on the server & appear on all my connected devices (phone, remote desktop & notebook).

When I am on the main work desktop, everything works flawlessly. I have access to whatever information I need. However, when I am on the other devices, all I see are the basic folders that reside on the server.

Could you suggest a creative way I could take the LOCAL FOLDERS along with me when I am outside the office? I was thinking of mounting the LOCAL FOLDER in the cloud, if that is possible. I will be the only one accessing it (single user) so colliding versions should not be an issue. I was thinking of copying the files on to an external drive then restoring to whichever device I use but the problem with this workaround is syncing back to the main machine.....a lot of extra work & steps.

Any suggestions? Hope to hear from someone soon. Thank you.

Once I delete a message, T-bird (147.0.4 on W11 Pro) begins compacting, and then I'm stuck until it's done. This is new behavior. Previously the system compacted occasionally, but now it's every single time I delete something from the inbox (which happens frequently during the day, of course, sigh).

Anyway, many thanks in advance for help/guidance and if it matters, I'm one of those who contributes monetarily for use versus freeloading. Also, no, we don't believe updating to the latest version is productive for our situation so I hope this is not the solutuion. -- Regards,

Je n'arrive plus à me connecter, voici le message d'erreur "Échec de la connexion depuis le serveur imap.sfr.fr avec le nom d’utilisateur beaudonnat.jean-luc@neuf.fr. Pouvez-vous me dire ce qu'il faut faire pour me connecter. A savoir j'ai changé mon mot de passe mais celui-ci ne me permet toujours pas d'accéder à mes mails.

Opening a link in email with control key now switches to browser (Firefox). Previously, pressing the control key when opening a link did not switch to browser. This is handy for opening multiple links in an email without switching to browser each time. Is there a setting somewhere to restore the previous behavior?

Hi, as of 14/4/26 my K9 (Samsung mobile) and Thunderbird (Mac Pro) no longer works with my bt internet account. Cannot receive or send emails. Have checked both in and outgoing server settings and all agree with bts advised settings. When I attempt to fetch in K9 I get error “network error readstringuntil():end of stream reached. Read:””while waiting for’’. When I attempt to send get message “unknown error unexpected end of stream. Contacted BT and they told me all my settings were good. I suspect something has changed at the BT server end. They did say they had relocated?? Any one else suffering this?

Hi there! I cannot get Thunderbird to work with the SMTP-server of my new Outlook account. I checked and double-checked the server specifications, the password, tried OAuth2 as well as login with password. I checked that SMTP is activated in my Outlook settings. Checked Thunderbird and my MacOS for updates as well, of course. I even created a new profile in Thunderbird. The result is still always: "authentification failed". Can someone help? Thanx...

When I receive an email that includes a live link it does not work when I click on it. Instead I get a popup error message that says "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

I can sometime manage to copy the link address and paste it into a browser but this is not always successful.

Good day, thank you in advance for your help.

I have two questions: 1. Which Thunderbird version is better than ESR? Could you share your opinion?

It's faster and it applies all changes more quickly, that's how it seems right now.

If there are still 32-bit and 64-bit versions available simultaneously, I'll test it sometime. I have no idea what kind of channel that would be.

Problem question:

In Thunderbird 64-bit POP3, the font changes to blue for every second email, including in replies. Can you tell me how to display every email in black? Only the second email in the inbox is displayed in blue, so the text isn't blue when receiving emails. When composing, everything looks black. What do I need to change?

Question 2: Regardless of whether it's 32-bit, 64-bit, or any channel, I see updates to the latest version, and in the program itself, there's an option to view older updates, but everything is white. I only see white and nothing else. Is this intentional? I can't see the update, but it's still current?

``` Thanks for the information

Using Thunderbird b150, but have tried -esr and regular TB. New install of Win11 26200.8037. Up to date Firefox. Have been trying for a week for Thunderbird to authenticate my Outlook account. Worked with Copilot. Finally found a TB setting, network.proxy.allow_hijacking_localhost, that was set to FALSE. Set it to TRUE and Outlook account authenticated. Able to finally send mail. This was last night. This morning: Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.office365.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again. No changed to any programs. Have deleted Outlook saved password. Thunderbird NEVER offers to get password/authenticate. I am truly and sincerely frustrated.

If someone can help me, would sincerely appreciate.

IMAP accounts, every time I open Thunderbird it has to authenticate and down load all my email; why isn't my all my current email available? And yes in settings I have "Keep messages in all folders for this account on this computer" checked. And yes in "Advanced" settings all folders are checked.
