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!

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

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

I'm using Discover to update Flatpak apps. A few days ago it updated to the latest 128 version of Thunderbird and I had subsequently made some changes to my profile and the details.

I wasn't paying attention this morning when updating via Discover and, once finished, found that Thunderbird had been downgraded to 115, leaving me unable to open it without the "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version." message.

I don't want to create a new profile, so what's the best way for me to switch back to 128 while maintaining the profile I had set up on it?

Thunderbird had been working perfectly for years under Mac OSX 10.13.6 (High Sierra) until this morning. Now attempts to start it result in an error message "You can't use this version of the application 'Thunderbird_78_10_0.app' with this version of MacOS. You have MacOS 10.13.6. The application requires MacOS 10.15 or later." The app shows a modified date of July 12, 2024, i.e., this morning and a size of 434.7MB. Perhaps it auto updated itself without checking that the update was compatible with the environment? Any suggestions about how to reverse that update or otherwise fix the problem would be appreciated!!! Garth Fletcher

Hello, I have a question about the interaction between the import profile functionality and IMAP synchronization. I am currently in the process of transferring a domain, and during that process the existing emails on the IMAP server for that domain will be lost.

If I have all the emails for that server in a thunderbird backup, and I then transfer the domain and set up another IMAP server for the same addresses, then restore the thunderbird backup, will the emails from the backup then be added to the new IMAP server? If not, does anyone have a recommended way to achieve this?

Thank you

Hi,

I have six IMAP email accounts that will cease to exist in a few weeks when I don't renew the domain/hosting where they reside.

Most of these accounts include invoices for purchases, and serial numbers etc that I need to have access to after the accounts will die, so just being able to read them offline. Even down the track when I inevitably build a new PC, I'll still want to have access to theses messages offline.

What is best practice for archiving or backing up these so I can still read them in future? Is there a way to archive so that I can read them in other clients in future? or I can only archive in a way that will be Thunderbird only?

Also... how do I get Thunderbird to allow me to read the messages from these accounts, without checking for new messages on these accounts, which would give error popups every time?

I've never had to do this before, and when I've searched around the results seem super confusing.

Any help would be greatly appreciated.

In case its relevant, my current Thunderbird version is 115.12.1 and running latest update of Win 10.
