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

Guten Tag,

Ich hoffe Ihr könnt mir helfen.

Ich benutze Thundebird das erste mal und würde gerne wissen wo meine gelöschten Mails hin verschoben werden wenn wie auf dem angehängten Bild keine Einstellung vorgenommen wurde standardmäßig. Werden die Mails dann direkt gelöscht aus der kompletten Mail-Adresse oder bleiben diese irgendwo gespeichert?

Die Gelöschten Mails sind im Mail Konto nicht mehr auffindbar.

Viele Grüße

I get the following error whenever I start Thunderbird :-

New to Thunderbird.

I have added a Gmail account to Thunderbird. I select a message in Inbox, right click > Move To > Local Folder

It seems to work. It creates a copy in Local Folder.

However, a few seconds later, the message reappears in the Inbox. The message in Local Folder is still there, confirming that copy is made successfully.

Also, the message is still in Gmail account when viewed from Google's Gmail. It's clearly working like Copy rather than Move.

This is frustrating. Is it a bug?

Hi Team,

Greetings!

I need your assistance regarding password protection for the Thunderbird email client.

I have configured an IMAP account in Thunderbird and enabled the **Primary Password** feature. However, if I cancel or skip the password prompt during startup, Thunderbird still opens successfully, and all previously synchronized email messages in the Inbox remain accessible. The user is also able to view the mailbox and access email content.

My requirement is that "Thunderbird should not open, display any email messages or allow Send/Receive operations unless the correct password is entered".

Could you please advise if this functionality is supported natively or suggest the recommended approach to achieve this?

Looking forward to your guidance.

Regards, Ps Cheema

As per the title. I have allowed external content for one message (it is disabled by default). Finding the option to do that was easy, because there is a specific message with a drop-down menu to configure access to external content for that particular message.

However, now that I have allowed external content, I do not wish to keep it allowed (no need for external parties to know when and where I open and re-open and re-re-open this e-mail). The drop-down menu to manage the privacy options for this particular message has disappeared. That is inconvenient, to say the least, because I can't see any other way to get to those options. What am I missing?

I have several MBOX files with me and I want to import MBOX files into the Thunderbird email client. I've come across different methods, including manual techniques and third-party tools, but I'm unsure which approach is the most efficient, especially when dealing with multiple or large-sized MBOX files. Some methods also seem complicated for users who are not very technical.

Suggest me any reliable tool for this!

I have been using Thunderbird for years. Suddenly, a couple of days ago, the sent and trash folders no longer show the emails in them. When I use Roundcube online, these files show up there as normal.

I have done considerable research online to solve this problem to no avail. Using AI, they suggest a number of things that I have tried, without solving the problem. Apparently, this is somewhat common. I finally got to deleting the send.msf and trash .msf. This did nothing to solve the problem.

This is very frustrating. What can I try next? I am using Win 11 and Version 152.

Dear Support,

we can not log-in with our office 365 account. We need to log-in with "Exchange Add-on erforderlich", but we receive this error message.

I attached you some screenshots. We do not understand why this error appears.

When we log-in with option "Exchange" then it works but we need the other option because we need to have the sub-folders.

Please help us.

Best regards, Andreas

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?

The system was working fine. The next day, when starting Thunderbird (TB, the status line shows logging in to server but loops; no errors or messages, Thunderbird is 'locked out' spinning. I see the normal INBOX page, but logging in never completes. NO CHANGES were made to TB accounts or settings. I have re-installed TB, re-booted, but no change. I cannot check/change any of the accounts or do any further 'debugging' because TB is spinning. The server login is fine because Webmail can be used. Internet connection is fine, because browser works. 1. How can I stop TB from trying to login at start up? 2. What could/would cause this behaviour?

Any suggestions much appreciated.

I have 'Allow remote content in messages' turned off.

When viewing a message with remote content, I see the bar "To protect your privacy, Thunderbird has blocked remote content in this message", however the 'Preferences' dropdown described in Remote Content in Messages does not exist...

I want to show remote content for a single message, but this seems impossible!

What am I doing wrong?

I am using Thunderbird as email client on Win 10. When trying to backup old messages I am getting en error message as below. I tried several ways exporting emails as “eml”, PDF’s or even plain text, but all the same. Following error message:

[Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref]" nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)" location: "JS frame :: chrome://mboximport/content/mboximport/utils.js :: getSubjectForHdr :: line 186" data: no]

Can anyone assist?

Thunderbird 140.7.1 i have a subfolder called "purchases" which I add to on a regular basis. Suddenly no messages appear after May 2014 I have logged in directly to the mail server, and all the missing messages are definitely on the server. I have checked the local filters, none are set. I have tried properties/repair. I have tried removing ~/.thunderbird/xxx/ImapMail/mail.myserver.com.au/INBOX.sbd/purchases.msf

Could it be a problem with dovecot indexing on the server? all the other subfolders seem to work fine. It's just this one.

I have thunderbird downloaded on my PC and would like to be able to access my emails normally sent to my Apple address ending in @Mac.com. I have tried to set this up on my own with no success, so I turned to ChatGPT and spent 4 hours going down the rabbit hole that is AI. Total waste of time!!!! Now turning to, probably, where I should have gone to in the first place, you guys!! I don't need to access calendars or contacts etc just the email. Can someone who maybe has done this using the @Mac.com email address give me some step by step instructions on how to do this? Any help would be greatly appreciated thanks👍 Kev

new computer. Downloaded thunderbird. Added old email accounts. I have 4. I cannot send emails out with primary account. I can get secondary emails to send out. SMtp is comcast.

Hi All,

Thuderbird 140.12.0esr (aarch64)

iMac 24Gb M4 Chip macOS Tahoe 26.4

When I request a search through Unified Folders Inbox for 10 email addresses using Quick Filter, CPU goes to 80% or more, and response is 10-15 seconds. Main search appears to be ok. Only add-on was a printer service but has been disabled and problem still remains. In troubleshooting mode, search still causes high CPU, even though I can only search one email address. Just started about 2-3 days ago (around 17-18 June).

Any ideas?

Thanks.
