My Spectrum password was changed and now I cannot get direct access to TB. For some reason TB is not linking up with Spectrum password. I get a popup panel saying "Login to server Mail.TWC.Com with username jomar159@hvc.rr.com failed" Retry Enter New password Cancel I have 2 accounts on TB 1 is wmarks1 and the other is jomar159@hvc.rr.com HELP

I have two Gmail email addresses. One is used for important messages. As of last Thursday I am not receiving some emails sent to this account. I asked sender to use secondary email and they come through. I’m very concerned that I’m missing important messages and need to get this corrected quickly. Please help if you can. If I need to delete Thunderbird I will but hope not.

Suddenly I am not receiving emails from my church and financial advisors (especially daily and weekly newsletters). They are NOT going into spam; I'm stumped. Appreciate your help.

In Outlook, it would say that "I replied to this message on xxx" in the header (not sure if that is what it is called, but near the top). I found it helpful to at least see if I have already replied to a message received. Is that feature available in TB?

Hello all!

I use Thunderbird as a local archive for my email. I have two accounts in the application: my home email via my ISP (POP) which I predominately use and my gmail (IMAP) which I don't generally use. There are years of messages in folders and sub-folder under the POP account, but nothing under the IMAP.

I’m up to date with Thunderbird at v140.1.0esr (aarch64) on my iMac with Sequoia 15.8.

On 07/22/2025 I went to download some messages via my ISP POP account and saw that a whole bunch of my email folders no longer had any subfolders and were empty of any messages. Some were also duplicated. Please see the attached image.

I haven’t changed any settings in years, and I do not have any add-ins. One of the nice things about Thunderbird has been its solidity and simplicity.

After every session, I would empty my trash and compact.

Suddenly my email seems to be gone along with sub-folders while top level folders are duplicated.

Wondering if anyone has any suggestions on how to troubleshoot this? Since I don't do anything fancy with the application and with the suddenness of this issue, I can't image I'm the only person having it? I’m quite concerned I may lose many years’ worth of messages.

Thanks much in advance! CPRoot

This pop message appeared about 4 hours ago. I still cannot recieved email. Do you know why and how long it before the system is working again.

I have used Thunderbird to manage my google calendar on PC, windows 11, for years. It seems now that when I add an event, hit save and close, it is not saved. All the events show. I can add events on my phone, and they show up in the calendar on Thunderbird, instantly. I just can no longer add events. I can try, but when I save, they do not appear in the Thunderbird calendar, or in Google. I did just recently change my password in Google, and had to re-authenticate Thunderbird, I suspect that's the instigator of the issue. I just feel I'm missing something. One note-if I click on "add account", there is no option for calendar anymore. Maybe this is gone.

I have previous ask questions on how to transfer profiles, local folders, sent messages, and all address from my old Windows 10 PC to a new Windows 11 PC. "David" provided a very help way to transfer the profiles between machines which helped immensely. However, I still do not seem to have the address book file(s).

Here is where I am and what I would like to be able to do.

When I first installed Thunderbird on the new PC, I set it up as an IMAP account with comcast.net. The contacts in the address book were showing. When I copied my Thunderbird profile from the old PC to get my Local Folders, the address book was gone. I repeated the install process and copying process to make sure I was not making an error. The results were the same each time.

What I would like to do is to find and directly copy the address file(s) from the old PC to the new. Is this possible and where are they located?

Thank you in advance to the time and patience to answer my question.

I've installed Thunderbird on new computer, and moved over from the old computer emails and Address Books (including customized ones). But when I start a new message, I can't get any e-addresses to appear in the To box.

What do I need to do to access Addresses?

I've used Thunderbird with the Owl add-on for Exchange/Outlook accounts for several years. Recently I've found when I open Thunderbird on my laptop, a tab opens for each account, apparently showing the Outlook web page for each account. This is great, but on the same version of Thunderbird (140.3.1esr) on my desktop, that doesn't happen. I can't see how to open these tabs there, or even how to reopen one of these tabs on my laptop, except from Go->Recently Closed Tabs. Am I missing something? What controls this behaviour?

Most of my Comcast Mail is going directly to Trash. Many of these e-mails have a green dot. What does this green dot mean? Why is all this happening? I don't have a problem with Outlook Mail or GMail?

Jag behöver hjälp med att Thunderbird inte längre fungerar vid lagring av mail. Varken till Arkivet eller Skickat mappen. Alltså jag kan inte se om jag skickat ett mail. Roland H

hi, my emails are set never to delete but they are disappearing after three weeks. If I scroll down today, I can't see any emails before the 16th of September. If I know what I am looking for, the emails appear in the search function. Does anyone know why they are not in the inbox? My settings are set so that emails never delete.

This issue has been confirmed on 140.3.1esr (64-bit).

When adding a new account via IMAPS/SMTPs connection, if it's the first time saving a draft or sending an email, the emails do not move to the Drafts or Sent Items folders as expected. Instead, they move to a newly created folder in the Local Folders. Furthermore, the special folder settings in the account configuration automatically change to point to the Local Folders instead of the connected IMAPs folder.

Testing with Thunderbird 128.14.0esr did not reproduce this issue.

I suspect this issue might stem from a mapping problem with Japanese folder names in the Japanese localization. (e.g., “下書き” as “Drafts”, ‘送信済みトレイ’ as “Sent”, etc...) Alternatively, could this be a change in behavior?

Thank you for your assistance.
