I need to use the offline MBOX folders of several email accounts that I access via IMAP to migrate the contents to a new provider. There are no files in my Thunderbird profile directory tree with the extension .MBOX (under Windows 11) but I have some fairly large files of the form: <Thunderbird profile>\ImapMail\<IMAP server>\INBOX and <Thunderbird profile>\ImapMail\<IMAP server>\Sent are these the MBOX files? Can I safely ignore the .msf files? A further problem is that I have more than one account on the same server, but the second account only appears as: <Thunderbird profile>\ImapMail\<IMAP server>-1\INBOX and <Thunderbird profile>\ImapMail\<IMAP server>-1\Sent How can I identify the corresponding e-mail accounts?

I created a user profile for IMAP and all was OK....Until I deleted the profile for POP and I lost all e-mail folders that I didn't move to IMAP. My PC is running Linux Mint. How do I get my lost e-mails?

送信トレイが消えました。 今まで送受信できていたメールアドレスがいつの日かメールの受信ができなくなってしまったため、ログアウトを行い、再ログインしたのですが、送信トレイの作成がされなくなりました。 メールを送ると添付画像のようなエラーが出てしまい、送信したメールを残すことができない状態になっているので改善策を教えてほしいです。

"Hello, I am using Thunderbird version 140.12.0 ESR 32-bit. I would like to install Thunderbird Setup 152.0. What are the advantages? Disadvantages? Is there a particular installation procedure?"

Hi,

I wanted Thunderbird to stop downloading messages from an old gmail account, but wanted to keep a kind of archive, so what I did was dragged all the account folders (Inbox, Sent, Trash) to Local Folders so that I can continue to reference downloaded emails (the account was using POP, not IMAP).

I'm on Windows 11. Inbox file is basically the same size as it used to be (just now in Local Folders) but Sent, Trash, other subfolders have all almost exactly doubled in filesize compared to what they were before I dragged (moved) the folders to Local Folders. I don't think there are doubles of messages when I look in Local Folders or anything.

Any ideas why the double filesizes? All the .msf filesizes are like, 15% smaller for some reason.

Thanks.

Why doesn't Thunderbird have a recall feature where I can recall and given sent email like those in Outlook and Exhange has?

You know there is good reasons for wanting that ability and be supprised to see how many people wish they didn't send that email.

Let me explain there is some one with the following email:

noreply@redcarpetradar.robly.com

Whatever anyone does do NOT click on their links I believe it's a criminal organization trying to get to my account.

I know many of you may not be in my situation but I'm a bit job hungry cause financial hit really hard. I clicked on link without looking and the site pretended I needed to fill a job application out. So I did without looking to see who sent it. Yes, STUPID me.

For some reason I marked as junk and it's not going to where I need to and that is trash and immediately delete it. I try and see if I can setup a rule for that. But wondering if there a extension that might do a better job. I tried to unsubscribe but these guys keep hitting back. That one sign of hackers trying to penetrate.

So now I'm wondering is there anything else I might be over looking. One think I keep thinking about is why NOT put something a tool that will do similar to mxtoolbox. With AI out there it's going to get harder to keep these criminals out of our inboxes.

I appreciate any feedback.

Every time I shut down my Windows 11 PC (25H2, x86-64), it gets stuck and states "This app is preventing shutdown", listing Thunderbird as the application that is the cause for the hold. If I don't react to this and force close Thunderbird at this point, my PC does not shut down. (Annoying if I hit "shut down" and walk away expecting the shutdown to complete.)

If I close Thunderbird before shutting down, Windows proceeds correctly.

How can I diagnose why Thunderbird seems to hold Windows active?

Downloading messages is now noticeably slower on an older desktop if the 'Inbox' folder is selected/focus. If focus is changed to a different folder (i.e. 'Sent') the message downloads become blazing fast.

Deleting messages seems slower as well and I think it is related. May involve inserting/deleting entries in the grid.

I had an account for my business. The account was hosted on Google; but was listed among my Tbird accounts. I closed the business; closed the Email account on gmail; and, I deleted all the folders, and the like from my Tbird client, every reference to the deleted account.

I continually get requests to login to my account. See the attached image.

Does anyone have any idea as to what I missed?

Thanks!

Is there a way to make Thunderbird check the server Junk folder when I open the Thunderbird Junk folder? When I empty my Junk folder, sometimes it will find there are more on the server and delete those too, so I never get to see them. Thanks

I am receiving the following error message when trying to send email through the Thunderbird client: Send Message Error "Sending of the message failed. An error occurred while sending mail. The mail server responded: <tbishop@typewire.com>: Sender address rejected: not owned by user tbishop@typewire.com. Please check the message recipient ("email") and try again."

I have checked the outgoing mail server (smtp) and tried several reconfigurations to get it working and ensure compliance with the ISP's configuration requirements - nothing works. Please advise...

I tried to connect my user on my Online Accounts on Linux Mint, but it said: Authentication Failed, so i tried to open my accounts and send a message to myself. The message is sent and it appears a little window that says: Your Messages was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can try or save the messages locally to Local Folders/Sent-(my e-mail name).

Same happens with Troubleshoot Mode and I don't think it's a connection error, so what is the file access error in here?

Hi everyone,

My antivirus as quarantined 2 files from my TB profile:

• d:\internet profiles\thunderbird\profiles\z3rq1w7t.default\prefs.js
• d:\internet profiles\thunderbird\profiles\z3rq1w7t.default\virtualfolders.dat

I asked the antivirus to restore them, but the damage is done. TB has lost track of everything I’d stored over the years, including my email accounts, emails, preferences, etc. It’s like a fresh install.

But I can see that my profile still contains about 5 bg of data. So everything’s there, but it seems it no longer knows how to access it.

As you can see, my profile isn’t buried in the depths of Windows; it’s on my D drive. Perhaps I just need to ‘reconnect’ TB to the correct profile, but I don’t know how to do that anymore…

Any help would be greatly appreciated.

Thanks in advance. Guy

Many times, I have a conversation with many messages. I may want to sort the array of conversation fields on any field. Currently, if I click on any field name, the conversation collapses.

My BT Mail (premium account) stopped working in Thunderbird about a month ago. I've been using it for many years without a problem, so can't understand what has changed. I'm using it on a desktop with Windows 11.

I had a long session with a tech person from BT, who couldn't find anything wrong. All the IMAP settings are correct. I have removed the saved passwords in Thunderbird and changed them via the webmail platform. I have uninstalled the account and tried to reinstall it but it won't set up the account at all now.

It works perfectly on Webmail and on my iphone so it must be something to do with Thunderbird itself.

I have thousands of emails saved so any help would be appreciated.

hi :-)

My Thunderbird uses between 19 and 34 GB of RAM. It's cyclical (with a period of about 10 minutes).

What do you suggest?

Do I need to perform a performance diagnostic? https://support.mozilla.org/en-US/kb/profiling-thunderbird-performance

Do I need to follow all the steps listed on https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems#Diagnosis_Steps, or can I skip some of them?

I have used Thunderbird for years and years and never had a problem. The last 2 weeks all of my outgoing emails have been going to everyone's SPAM folders. I have an AT&T email account and I use the AT&T Pop server settings, for the Outgoing Server I have the Comcast/Xfinity settings. I receive emails with no problems, it is my outgoing emails only. I don't know if it is a Comcast problem, an AT&T problem or Thunderbird problem. I have been on the phone with Xfinity for 2.5 hours and still having problems. Any suggestions.

I keep getting prompt with this message stating the current config is set to block cookies (attached screenshot) and is occurring every interval. I had updated the app yesterday, some how after restarting the computer, it's popping up with the message.
