Thunderbird for Windows stuck on startup. The status bar shows "Looking up imap.google.com...". The title bar shows "Home - Mozilla Thunderbird (Not responding)". When I close Thunderbird, it gives me a "Not responding" dialog and then says that it is reporting the problem to Microsoft.

This problem has been happening for the last few weeks but this is the first opportunity I've had to tackle the problem. I've done a few searches but nothing pops up for this problem. Any help would be appreciated.

Windows 10 Pro. Latest version of Thunderbird for Windows as of a few weeks ago. The problem was happening before I upgraded the software to the latest version.

I am trying to switch from using ATT to access my email to using Thunderbird. I have tried the "auto" function where the current configuration pops up to manually setting the configuration with ATT server recommended settings all to no avail. What am I doing wrong?

I am experiencing a symptom sometimes when I delete a message in the Thunderbord email client (in any folder), all messages disappearing from all accounts in the entire Thunderbird including Inbox, Drafts, Trash, Sent and everything else. All folders become empty. The messages are not deleted, just not showing. Using the Trash icon of Thunderbird or pressing the delete key are the same. There is no way to display the messages again except to close and re-open Thunderbird. After that, everything return to normal. This does not always happen, about 75% of time. Thunderbird version is 128.6.0esr (64-bit), Windows 11 but the same also happened on previous versions and Windows 10.

See description in Subject line. Can't download new email from POP account since 10 a.m. EST January 14 2025 Tried recreating global-messages-db.sqlite file in Profile. Process worked but no change to email status. I can open old email and can send new. HINT--TBird no longer requires my PWD to read and send! Any suggestions for how to regain access to new email? Running Tbird 128.6.0 on Dell machine with Windows 11. Email continues to show up on my iPhone and via web mail access to my provider, Astound, as rcn.net From looking at the user forum, it seems that something may have gone haywire with email downloads when T-bird was updated to 128.6--is that the problem source? If so, how to fix that?

Like the title says, I am getting some emails that move from Unified Inbox to an IMAP subfolder of account X, but remain visible in the UNIFIED Inbox.

First uploaded image shows 3 IMAP accounts as they appear in Thunderbird, second uploaded image shows how subfolders appear in IMAP account X (the third account in Thunderbird).

Mail is properly arriving in the 3rd account and shows up in both IMAP and Unified Inboxes, but only sometimes (and not with specific senders) can be moved into the 3rd account subfolder.

They are correctly removed from the IMAP Inbox but remain visible in the UNIFIED inbox and are found when I search in the UNIFIED inbox but not in the IMAP Inbox.

The messages persist in the UNIFIED Inbox through multiple restarts of Thunderbird and my PC, and some email continues to arrive in the 3rd account and cam be moved as expected, then another arrives that cannot be removed.

Strangely, if I delete the mail from the UNIFIED inbox, it is deleted both there and in the subfolder, so it appears something is making the display of the UNIFIED inbox keep a link to the new location of the email.

Bleah!

Any body see anything similar? I read several older threads about move problems, but this seems different.

Thanks!

Thunderbird BETA 135.0b1 (64-bit) Probably not very interesting but: Windows 11 Home; 23H2; OS build 22631.4751; Windows Feature Experience Pack 1000.22700.1055.0 11th Gen Intel(R) Core(TM) i7-1195G7 @ 2.90GHz 2.92 16.0 GB (15.7 GB usable) 64-bit operating system, x64-based processor

After new installation of windows 11 and Thunderbird at 15.Jan 2025 the connetion to my e-mail accounts cannot be opened by saved passwords - every time I open Thunderbird I have to tip in my passwords. Very uncomfortably.

Hello, I want to change first day of the week to Monday (who on earth would have Sunday as the fist work day??) Problem: All instructions online are useless since there is no "Options" / no "Preferences" / in Settings there is no "Calendar" or anything referring to Calendar. Under Settings there is only General, Composition, Privacy & Security, Chat and Export for Mobile. Nothing for Calendar. Also in Calendar view ... nothing to change days order. All online articles seem to be outdated (2021 and older)and don't apply anymore. Someone advised the reboot Thunderbird ... ? How to do that? Just close it down at the X?

Please help.

Thanks

Depuis 2 jours, je ne peux plus envoyer de courriel avec ma messagerie Thunderbird. J'ai tout essayé, rien ne fonctionne !!! je me suis créé un compte Gmail et la, tout va bien. Je vais donc quitter thunderbird et par la même occasion firefox. Merci mozilla 111

Mail is downloading to Thunderbird, but is not going to inbox. I can only see it if I search in the universal search tool, asking to see all the mail from today's date. I can't figure out where it's going! This is a new issue, after thousands of successful downloads from my domain.

I changed from POP3 to IMAP and when I reconfigured TB 78.14.0 all seemed good until I tried to call up messages in subfolders of the INBOX. The folders and content are still on the server and it seemed impossible to subscribe to the INBOX in TB. The INBOX itself still functions with new mail and older content showing. The locations of the subfolders had an IMAP mention in the directories that was additional/instead of simply ....'mail.xxxx.xx' but changing to IMAP instead of 'Mail' in the server settings was futile. A deep dive into mozilla resources led to mention of leaving empty the IMAP server directory field (Server Settings>Advanced), and putting "INBOX." (with the following period critical, but quotes not) in the personal namespace field. See: https://kb.mozillazine.org/IMAP:_advanced_account_configuration This worked! However under 'personal namespace' it reverted to double quotation marks ("").

I believe that since the update, I have not been able to access my emails or send emails. The password is not being recognized and I cannot receive or respond to my business emails.

Receiving the above message when trying to get emails. Am able to receive emails on cell phone which is not with Thunderbird email. Made no changes to Thunderbird. Started about 2 days ago. Spoke with our email provider and they say it is specific to our Thunderbird email.

Entire message reads - " The certificate for pop.starpower.net is not valid for that server. Someone could be trying to impersonate the server and you should not continue "

                                                                                                       Mike Worden

A number of times during the day, when I'm on my email account a window interrupts me to verify my account ( photo attached) After I follow all prompts repeatedly over many times a strange series of slashes cross the top of my window and it asks me if I want to go back to my previous last email. I can not proceed with my activity. So I close the computer and wait a couple of hours and try to start up, BUT my password box is filled with dots. I am unable to continue. So I wait longer. When I do get access it all starts over again. Is this you or google doing this? I have been with Thunderbird for years, and I hate the idea of having to go through Google to use you. Yesterday it locked me out of my computer in total. Need help!

I have email through AT&T, hosted by Yahoo, and have synched my calendar for years. It has now stopped enabling and updating. In calendar screen, grey ENABLE button now shows. Click it and I see a quick flash of items and instantly disappear. Nothing happens.

Select properties and the enable box is not checked. I can check it, click OK and again it won't enable. On my to do lists for this account, same issue. Click enable, it flashes the items and then they disappear. Won't stay enabled.

Contacts still sync so appears to be a caldav issue.

Was working fine, but stopped a few weeks ago. I can't find a solution. Help please.

I have a block of emails in my inbox that I cannot delete. I can delete emails above the block and below the block. There are four emails received on December 24. They will not delete. I deleted the trash files from the profile folder and still no success. I also restarted Thunderbird in safe mode. I am using version 128.6.0esr

For a few days, on all our PCs, when I forward certified emails (PEC) the body of the email is empty! This only works if I forward "as attachment" otherwise the body of the email is empty without any attachment. It only happens with PEC (Certified Email) emails, while with "normal" emails everything is fine. >> In the menu bar Select Tools-Options-Composition-General option is set to Inline.

Has anything changed? Anyone have this problem? I've really tried them all!

thanks
