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

Can you configure Microsoft shared mailboxes, as outlined in https://learn.microsoft.com/en-us/microsoft-365/admin/email/about-shared-mailboxes?view=o365-worldwide, in Thunderbird. If so, can you tell me how? If not, is it on the roadmap?

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?

When I try to send email I get this error message Sending of the message failed. An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

Hi, I'm using Thunderbird 115.4.1 and Windows 8.1 Pro. Ever since the Supernova update, TB crashes pretty much daily (up to 3x a day). I turned off auto-updates as soon as I found out how to, since everything was so confusing and didn't work the way I was used to. Now I'm afraid to do any more updates since I don't want a whole bunch of other things to get screwed up. I have learned to kind of work around the problem areas, though it's frustrating. But I don't want to spend another 10-15 hours trying to fix new problems. Any suggestions? I can't seem to find any information about people who have had this crashing problem and then had it resolved through an update. Thanks

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!

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

I had to switch web hosting providers. Since changing to name.com, my outgoing emails from Thunderbird associated with that account are being returned undeliverable as having been marked as spam or unable to authenticate. Copy of failed message attached, along with server settings. Also, this morning I received a notice from Zimbra requiring authentication? I have no idea what this is. Email sent from name.com dashboard are successfully sending.

Hi, I am following instructions to download and import all my previous google account files over to the new account. Google Takeout instructed to use Mozilla Thunderbird. I downloaded as a zip, installed the ImportExportTools NG as an Add On in Thunderbird and have been trying unsuccessfully to import the files. Any tips?

I started up my machine this morning, for Thunderbird 115.13 (I could've sworn that I had a later version last night, but updates and version numbers are Mozilla's problem, not mine) tells me that I can no longer use my profile with this fancy new version and need to create another one. After fuming about that idiocy for a while, I canceled the process and imported everything from my old profile.

It fouled up mightily on the passwords, but I got past that obstacle course.

Now, I see that my "Today Pane" is empty. Looking at the calendar, I see why: Thunderbird apparently pretended to import three calendars, but skipped all but two old events. I can create more empty calendars, but that is incredibly unhelpful. One calendar is local. One is an online ICS file published by an organization. And the third (the one that had two events picked up) is subscribed to an OwnCloud account's calendar, and may have worked. The first is obviously the most important, since I'd rather not spend time working out the database schema so that I can manually input every single event and appointment.

What hoops do I need to jump through to refill my calendar? I'm running on Pop!_OS 22.04 LTS, with the Thunderbird Flatpak (commit c2e09fc595198cf5c467ddad1fab56c0be512758584e16c3b933f2410968306a according to the command-line, if that gives any clues) installed. And again, I feel like that setup used a significantly later version of Thunderbird recently, so figuring out how to undo Flatpak's decision to downgrade would also presumably solve the problem.

I stupidly deleted Thunderbird and now i lost my addresses ad not sure i can get them back can someone remote and help me with it see this but too complicated for me for me i had a guy from Just answers do it he made a test profile and it took up of space and i saww all sorts of profiles so i thoughtit would work removing it but it did not i removed and lost all profiles

had to totally  uninstall and reinstall  and now  i an not  get it back

'bold text'bold textOn 6/24, Juno Security <security@support.juno.com> sent me an email that Thunderbird downloaded that my account had been compromised, & I needed to reset my password. I chanced my password in Juno & put that same password into Thunderbird [I think] Since then I have needed to use that new password to open the Thunderbird program, but Thunderbird won't download email from my Juno popmail to Thunderbird. Thanks for your help.
