I accidentally deleted a POP account and I lost every folder that I had on that account, how can I recover it?

I tried with some recovery programs but it didn't work

"Mail to" extensions and "Send to" do not work with Thunderbird. I'm on Windows 11 and use Chrome, Firefox and the Microsoft Browser. None of them work. Thunderbird works fine on it's own but those options don't work. Thunderbird is the default Mail program.

When I right click on a file and use "Send To", Microsoft Outlook opens.

When I use a Mail To extension or Send to Mail extention (Neither works), my browser tries to go here mailto:?subject=Send%20to%20Mail%20%E2%80%93%20Get%20this%20Extension%20for%20%F0%9F%A6%8A%20Firefox%20(en-US)&body=https%3A%2F%2Faddons.mozilla.org%2Fen-US%2Ffirefox%2Faddon%2Fsend-to-mail%2F%3Futm_source%3Daddons.mozilla.org%26utm_medium%3Dreferral%26utm_content%3Dsearch

and I see a popup that says Send To Mail Opening Mail Handler

Any Help?

I have been using Thunderbird for many years and have previously updated without problem. But upon updating to version 128.0.1esr I suddenly couldn't see my folders or emails (see attached image). However, if I search for an email I will get a list containing the relevant emails, but as soon as I click on an email in the list I go back to the blank screen like at login with no folders or emails.

I have trawled through related fixes and have tried clearing the startup cache, restart and reinstall Thunderbird but nothing helped .

I'm unable to connect Thunderbird to my icloud calendar. I was able to locate the calendar url through my icloud account, but I could not get the set up process to recognize my password. I tried using my icloud password, my email account password, and the app specific password for my email server. Not sure what else to try.

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

   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?

I asked Thunderbird to archive the emails from the first few months of 2024. It created a 2024 folder under the Archives tab. But there are no emails. They have disappeared! Is there any way to recover the deleted emails?

I use the Search Box on the top line of Thunderbird. I have been double-clicking the box to get to a full-page search entry (Duck-Duck-Go).

As of today (6-Aug-24), this no longer works. The only places to search are the address bar, or a very short search bar.

Did this change in the last update? Can it be restored?

Thanks, Lex Rutter Idaho

'Have enabled and disabled. restarted, both times. Tried troubleshooting mode, and cleared the cache. Could not find the setting in the config screen. Not sure I was looking for the right thing, anyway. Your help will be greatly appreciated. John Looze

This evening, Thunderbird has updated to the new version (can't see where the version number is held, unfortunately). Whenever I try to download new emails, I now get the message "Error with account [email address]. Sending of username did not succeed. Mail server pop3.iomartcloud.com responded: Mate, the command must be one of CAPA, USER, PASS or QUIT." Mails are still accessible through the mail client on my phone and through webmail, just not through Thunderbird.

I am currently on Ver 115.12.2 (32-bit), but I've had this problem over several versions. I recently downgraded from the 64bit version (for a different reason), it had the same issue.

Old messages in the Inbox are listed twice, including those that have been read. New incoming messages are not duplicated, messages where I've deleted the duplicates are not again duped. Messages that get filtered to or moved to folders are not duped. Old messages that are in folders are not duped.

I have several email accounts in TB, and I only see this on my most active- of course! I have compacted all folders many times and rebuilt the Global Database with no effect. I tried opening in Troubleshooting mode and they are still duplicated. It is a POP account.

I cannot receive or send any emails. Server is not authenticating. This is a sudden fault. Thunderbird is updated to 128.0.1esr (64-bit). Opening Thunderbird shows message "Authentication failure while connecting to Thunderbird imap.gmail.com”.

What is the fix for this?

Hi,

I'm using Thunderbird 128.0.1 on Mac OS 14.5, and recently (not sure when exactly), none of the normal messaging options like reply, reply-all, or forward are available. I still can start a new message, though.

Thanks.

I update my Thunderbird yesterday afternoon to the newest version. Now when I click my icon to launch it it launches a second default gear icon with the hover text reading "thunderbird-esr". I purged the install and reinstalled with the same issue. I'm using Pop!_OS on Wayland if that helps.

Since we upgraded to 115, most of our PC cannot forward email larger than 5MB to team members. One or two PC can sometimes send without problem but not always.

We can press "forward" and the compose new email window comes up as it has always been. But when we press "send", it will stall for a while then responded "Cannot send email". Press "OK" and sometimes it will then respond "Creating email" or something like that. The sequence could be reversed (create first then cannot send). Cannot even save as Draft into the Draft folder on our own manged MDaemon mail server on our local LAN.

Thinking it is all due to the forwarded email being too big, tried many many times over weeks checking MD setting, LAN and individual local PC setting but still cannot resolve.

Today I tried something completely different. Instead of "forwarding one large email", I tried to attach large attachments like .jpg etc and found that it is the "attachment process" that is causing the problem. If I attach a larger file, say 10MB, it is problem. If I attach several small files, it sometimes go through even the total file size exceed 10MB. The I tried attaching just a few attachments, save to draft folder, close the compose window, re-select the draft email and then add more file. Repeating this several times I managed to be able to save to draft folder on the server and then send out an email of 49.9MB. I keep on playing with it for hours but I could repeat and can only managed to do something like 10MB/11MB.

This is still much better than trying to "forward an email" (as attachment or in-line) which we can only do up to about 5MB max.

Please help to resole this problem.

Have no clue what I am doing. I have downloaded Thunderbird so I can access my bt internet emails (webmail is having issues)and have fallen at the first hurdle! I need someone to put in easy words what I am to do please. I have inputted my email address and password and it says unable to log in at server.

Hi all, I am a long time Thunderbird user on all my Windows machines. Today I installed Thunderbird 128.0.1esr (64bit) on fresh Win11 machine. I successfully added my gmail account to Thunderbird. I have issue with my other account - the SSL cert is issued not for this specific domain and I get warning about this but I can't accept this as exception - it appears again right after clicking "accept exception". I know this is about SSL cert but I want to accept this exception.

On another Win machine I had configured both accounts for ages - it stopped to connect to this server right after upgrading to 128.0.1esr.

Disabling SSL scanning in ESET or disabling protection at all is not helping. When I change configuration from "STARTSSL" to "NONE" it then connects to the server. The issue is with accepting exception in Thunderbird. Do you have any suggestions?

Kind regards Daniel
