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?

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

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!

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

Neither my wife nor I can access email on our respective PCs. This has been the case for four weeks. We can access email by our Android phones, but we really want to use our PCs. I've tried to resolve the problem and failed. Previous to this failure, I had an account with BT but this was transferred to EE. When I attempt to log in to my mail account, I receive the message "Could not connect ... :the connection was refused". I can also add is that in my Account settings, Outgoing Mail server I see a message "Connection to server mail.btinternet.com:465 failed."

Needed to ire install thunderbird email and could not get past the "donation" page Paid a "donation" and still cannot get past the donation page The release channel button did nothing Am thinking the donation is a scam How Can I use thunderbird for emails Margaret

bold texti have a thunderbird profile on exterior drive I have installed linux mint on my PC but cannot locate the profile to use my old TB profile -either by replacing it or renaming the old profile for the linux one

I get a message saying "The certificate is invalid." And I am currently unable to receive emails. When I open the server settings screen, it says "The certificate exception already exists."

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.

Hi

I have a problem with Thunderbird which might be a bit niche but here goes...

The first attempt at sending an email fails as TLS Record Layer v1 is used, the mail server sees this and hard resets the connection so sending halts. See attached Wireshark trace screenshot "Failed".

If I retry the send again Thunderbird uses TLS Record Layer v1.3 and the email goes out ok. See attached Wireshark trace screenshot "Success".

If I send another message immediately no problem but if I wait 20-30 minutes the above cycle happens again.

I have set the minimum TLS version in the config to 1.3 (option 4) and restarted Thunderbird but this has not changed anything.

Any ideas how I can fix this? It's a pain because automated replies don't work.

I have a fresh install of Thunderbird from yesterday. Never was on this machine before. Setting up 2 mail accounts worked well. I can select multiple messages using either ctrl+click to select individual messages or shift+click to select a range of messages. They all get highlighted as one would expect, but when I drag them to another folder, or choose from the right-click options like move or copy or archive, this action is performed only for the first message that I clicked. I am sure this did work before and I have no idea what I might have changed so that it does not work anymore. I transfered a lot of messages from one account to the other without problems. I changed archive options, installed the AutoArchive addon, changed folder icon colours, ... Can't remeber everything, sorry. On a side-note, AutoArchive is also only archiving one single message from every folder, so the underlying mechanism is the same.

TB address book has duplicate entries or other entries that will not delete or edit? Tried to even change the name. Close reopen and it reverts back to original. ??? Thanks for the help.

A few weeks ago my installation of Thunderbird on my Windows 10 laptop was version 151. I want to stop it from being updated, and I asked AI for help. It suggested the following:

1. Create a directory named "distribution" and locate it as follows: C:\Program Files\Mozilla Thunderbird\distribution. 2. Within that directory, I was asked to create a file named "policies.json" and I did so. 3. Within that file, I was asked to place the following: {

 "policies": { 
     "DisableAppUpdate": true 
  } 

} and that's what I did.

When I had a look under Settings > Update, there was a note to say that updates have been prevented by the administrator. (That would have been the effect of what I just did.) That was a few weeks ago.

So, when I looked at my version number today, I saw that my version is now 152. It had updated, and the directory and file I created are now no longer present.

It seems that the update process deletes anything that shouldn't be there and doesn't trouble itself with the file I created.

How do I stop Thunderbird from updating my installation?

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?
