Thunderbird 115.12.1 running on Windows 11 in S mode. Working fine for several months, until today my wife clicked on a particular message, then Thunderbird hung, displaying a tab with "Loading" and the path to the inbox and message, and not responding to any user actions. Killing Thunderbird and restarting results in the same situation. Thunderbird is trying to start up where it was when it was killed. It appears that something in the message causes this problem. I have tried the following:

• Tried to clear the startup cache, which I am able to access by bringing up the "Write new message" window. However this action starts the main Thunderbird window, which immediately hangs. Also tried starting in Troubleshooting mode, with the same result.

• I tried to navigate to the Inbox in Explorer, hoping to delete the offending message. But under AppData/Roaming, I saw only two folders (Adobe and Microsoft), but no Thunderbird folder. I made sure to unhide hidden files in the Roaming folder, but it did not help. I also tried this as the user (me) who set up the system and is presumably more privileged but that did not help. I am not knowledgeable enough about Windows 11 security to know how to overcome this. It seems like some kind of super-hiding that only Thunderbird can get through ??

I can try deinstalling and reinstalling Thunderbird but would like to get some thoughts on this before I go that route.

Thanks

Hi, I am planning the switch from GroupWise into a hosted mail solution - using Thunderbird as the client. I have with issues connected Thunderbird to the current GW server but I only see and get 4,000 emails in the Sent folder - the server has well over 11,000. How can I force Thunderbird to read them all? Best regards

How can I change the subject prefix (Re:, Fwd:, etc.) ? I would prefer "RE:" to "Re:" for my outgoing mails. "mailnews.localizedRe" handles recognition of incoming subject prefixes, but I found no pref for my outgoing mails. Thank you!

My laptop using Windows7, the processor died. The hard drive is ok. I am now using Windows10 in a newer laptop. I don't know how to access all the data from the other. I don't think I did a back up. I've got both personal & business. Is there a way to retrieve my old Thunderbird info? [And just so you know, I learned my lesson about not backing up.] And thank you for any help!

So Microsoft sent one of those "take action or lose access to your account (btw, Thunderbird sux, use Outlook instead, nudge, nudge, wink, wink)" e-mails to me. So I've beeen jumping through an unholy amount of hoops in order to find out what I'm supposed to do in order to fix whatever it is that needs fixing. I seem to have found the answer here: https://support.microsoft.com/en-us/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d. They were even "kind" enough to include specific instructions for Thunderbird. I did step 1 successfully, but unfortunately I'm stuck at step 2 because the Authetication method selector won't offer OAuth2 at all, as you can see here: https://i.postimg.cc/mrSstFtt/Captura.png.

1. What am I doing wrong? 2. How can I set my outgoing mail server to use OAuth2, then? 3. Do I need to anyway?

Hope you can give me a hand, so far this has been way more trouble than it needed to be. And after I sort it out I still need to do the same for K-9 on my phone -_-'.

Is thunderbird down?? I cannot seem to get or send e-mails. This has been going on since morning.. Since I cannot get an e-mail could you respond by text to my cel phone? [edited phone# from public community forum].

I am new to Thunderbird and I store my Gmail’s in different storage folders which show up in my Thunderbird menu. How do I move individual emails to different designated storage folders. I do not want to use dragon drop because I might want to do a number of them so how do I simply move an individual email into a storage folder

I got this notification:

"You must have the 'Encrypt' button present in your compose window toolbar to be able to schedule messages with Send Later. If you removed it some point, you need to customize the toolbar and put it back. This is due to a Thunderbird bug which we hope will be fixed soon."

I don't use encryption, but do use "Send Later." I also never removed the button. I tried to customize both the main toolbar and the one in the composition window; neither one had a button under "customize" for encryption. Can anyone help with this?

Dear Mr/Ms, Can you give me one rational answer why is missing icon "Compose new message" in new version of thunderbird? The purpose of use of email app is to sent and receive emails, isn't it? Im very dissaaponted by this move. Did you ask any user when plain to improve app? My advice is to ask people who use thunderbird app.

In anticipation of exporting a subfolder to pdf I moved and renamed it, then ended up moving it back. Not sure what happened in that process but... My 98 emails are in the subfolder when I view it in TB, but when I view it in explorer there is a .msf file but no actual file with that name. Looking through, it appears some other subfolders are missing too (in some cases the file and the .msf) but all the emails are there when I view through Thunderbird. I tried repairing the folder but that didn't help, and it won't seem to compact. I deleted the foldertree.json and that didn't help.

I am looking in Users/NAME/AppData/Roaming/Thunderbird/Profiles/XXXXX/ImapMail/imap.ionos.com/FOLDER/SUBFOLDER/SUBFOLDER (this is the path with files that have today's date).

What's my next step? Thanks

I have Thunderbird 128 installed and just tried to get my gmail account set up. Everytime I try to add it, the Oauth window comes up, I log into Google, and then get a "malformed url" error and the oauth fails.

Anyone else have this problem with 128? Is there a workaround?

Sorry I'm not making myself clear. I want to save the emails to where I can access them if needed later. After I have that I want to delete the older emails in Gmail to make the inbox and folders smaller. Thunderbird will then sync the inbox which will be considerably smaller. It appears that archiving will do this but I don't know how to copy the emails to Local Folders. It appears that Thunderbird will still be able to search & find the old emails if I need them. After deleting them, Thunderbird will be syncing the smaller inbox instead of all of them. I copied the Profiles directory from the appdata string to an external drive which it appears I have backed the profile up.

質問お願い致します。 先程、誤ってメールを送信してしまいました。 受信側のメールも削除したいのです。 申し訳ありません。 回答よろしくお願い致します。

Please ask any questions. I sent an email by mistake earlier. I also want to delete the email on the receiving side. very sorry. Thank you for your reply.

I have several Comcast.net accounts that I have set up in Thunderbird. About 2-3 times per week, Thunderbird makes me re-enter one or more of my passwords, only for the comcast accounts. It says Authentication Failure, but I have not changed anything on the accounts, including passwords. Entering the same password works - for a while. Any idea how to stop this?

Hi guys, an automatic update seem to have made my Thunderbird Flatpak unusable. I have literally thousands of Emails in several Accounts as POP3 and need to access them. Suddenly since today I get the error message "You have launched an older version of Thunderbird" (Create New Profile) (Quit). Both choices are not acceptable for me. Any ideas what I can do? Any help is appreciated!

I recently tried moving the thunderbird profile folders to a different hard drive (D) as they were bloating up my boot drive (C). After unsuccessfully attempting to move them through thunderbird itself, I manually dragged them onto a different drive and attempted to import the settings via the import tool, to no avail. After restarting thunderbird, it reset itself completely and I had to log into all the emails tied to it again. It then proceeded to somehow redownload my profiles onto the original hard drive (C), but all the local files, despite being present in AppData/Roaming, are not present in thunderbird itself.

Any help recovering those local folders would be greatly appreciated.

Hi, Recently Kaspersky antivirus (Premium) started picking up potential threats. It points to files in C: users\lther\appdata\roaming\thunderbird\profiles\tzldd93i.default\mail\pop3.iafrica.com\sent....

I have deleted the files in Thunderbird under sent files, but they still get picked up by Kaspersky. There is no option to delete them in Kaspersky, only to exclude or ignore. I do not want to manually delete all sent files, I cannot see the individual files in windows (win 10) anyway.

Is there a way to fix this. Kaspersky support have tried but no success.

Regards Leon
