Thunderbird Community Forum

All of a sudden, I go to send an email on one account. and Account I use on people I do not trust yet, And ALL OF A SUDDEN, the email is put in my Most protected email account, as sent. And when I LOOK, the sent email has BOTH emails as "FROM". Talk about insecure and a violation.

Now my IMPORTANT and PROTECTED email is out there with people I don't trust so much. Thanks. Is it from a recent Botched Update?

The work Ahead is gonna kill me .

I am trying to add a new identity, I already have 3, so perhaps there is a limit? I have created the identity under manage identities with no problems. However, the new identity does not appear in Thunderbird, where the others are. The address is not recognized, and does not receive emails. I feel like I have missed a fundamental step but have followed the help instructions & cannot see what I am doing wrong. Ive checked and the program is up to date. I hope someone can offer advice thanks Anne

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 receive messages ok - but can t send. Malwarebytes is my antivirus software.

First time it happened - took laptop tp local computer repair shop -they told me they turned off 'VPN" and it startedf sending email.

Then stopped again - it seemed after Thunderbird update. Took back to shop - person that fixed it was working there any longer.VPN is off Thunderbird version is 140.12

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 was able to successfully set up my gmail account, but there's a problem with my iCloud (me.com/mac.com) account. This account is accessible on my iPhone and also on my laptop. I don't really know where to begin troubleshooting this. By clicking on Manual configuration I can see Thunderbird's best guess, listed below:

Protocol: IMAP Hostname: imap.mail.me.com Port: 993 Connection security: SSL/TLS Authentication method: Normal password Username: johnwgordon Hostname: smtp.mail.me.com Port: 587 Connection security: STARTTLS Authentication method: Normal password Username: johnwgordon@maccom

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."

I have a Yahoo.ca email address and have been using Thunderbird to retrieve my email for years. For some reason, a window now pops up to Rogers.com and they want me to log in there. This is not a Rogers email address and it is separate from Rogers. I had this issue before and this forum managed to get me back. My settings are correct. I have deleted the profile 5 times and added it back after a computer restart and still nothing.

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 all,

I installed Thunderbird a few months ago to transfer emails from an email account that is about to be shut down to my Google email account.

I now want to uninstall Thunderbird (and delete all its files from my computer, including emails) but am worried my Google emails will also get deleted (e.g., due to syncing?) in this process.

I would have loved to keep Thunderbird installed but, due to my personal laptop being unavailable when this email transfer began a few months ago, I had to install Thunderbird on my work laptop instead, and I do not want Thunderbird to stay on my work laptop anymore (my employer allows employees to install any software but I will feel better if I just delete Thunderbird from the work laptop at this point).

Please advise, thanks.

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?

Hello.I just want to let you know,that somehow the client what i uzsdeing is forget to make undread massages to read when i takea look at them.When i double clivck on them they open a diffferent page and then they get read status.What could cause this?

I have an old iMac running macOS High Sierra. After a power surge last night, I have been unable to access any mail accounts. Apparently this is because my iMac cannot use two-factor authorization. The recommended fix is to use Mozilla Thunderbird. I downloaded this, but when I double-click the .dmg file, I get a corrupt image message. I am wondering if this is because I have a 32-bit machine.

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.

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

Hello everyone

It's been for a few days since somehow it became unable to send mail. The error message is "The message could not be sent because we were unable to connect to the outgoing (SMTP) server smtp.gmail.com. The server may be unavailable, or the SMTP connection may have been rejected. Please verify that your outgoing (SMTP) server settings are correct and try again. Problem is I cannot see any mistake in my smtp setting. Some help much appreciated. Thank you.

[Edit:] I'm using Kubuntu with Thunderbird installed via flatpak using the flathub repo.

When attempting to add my calendars on our Nextcloud server, I can't get further then the second dialog.

Steps to reproduce: 1. New account > Calendar 2. Select "On the network" 3. Enter the correct user name and address (I did try the server address AND both CalDAV addresses presented in the calendar settings on the Nextcloud web app). 4. Press "Search for calendars" 5. After an extended period of time a dialog with a title "Adding a security exception" appears, claiming, that our Nextcloud site does not have a correct certificate (it does).

This is where the journey ends. If you add an exception, the dialog disappears and you are still at number 3. Trying again will produce the same result. Funny thing is, that you can press the button "Load certificate" in the "exception dialog" and then the same dialog will declare that our site does indeed have a correct certificate! But it will only allow you to close the dialog and you are still at number 3 and without any chance to add your calendars.

This is a completely new installation of Thunderbird. There are other folks that are using Thunderbird with their calendars on the same Nextcloud server and everything works happily. I presume this is a bug with the newer version of Thunderbird or something of that sort.

Hi there,

I currently have three email accounts set up in my Thunderbird client. I’d like to disable the automatic marking of messages as read—but only for one specific account (mainly for my colleagues’ convenience, as it’s a shared inbox).

In Settings > General, I see the option to turn off "Automatically mark messages as read", but this would apply to all my accounts, which isn’t what I want. I’ve checked the Account Settings for the relevant account and couldn’t find a per-account option. I also looked for an add-on that might help, but so far, no luck.

Has anyone found a workaround or solution for this? Any advice would be greatly appreciated !

Thanks in advance, Cheers.
