My Send short cut has disappeared.. I also have the "send later" add on to my Thunderbird. I seem unable to send messages. Is there a key board short cut to for sending mail? My old Eudora account used to have one a <Ctl> S.... (With Thunderbird this is Save, instead of send).

When choosing to edit a sent message as a 'new' message, placing the cursor at the beginning of the message and pressing <Enter> does not advance the text.

It used to.

Placing the cursor at any other location within the message WILL advance the text with <Enter>.

I CAN add text by typing, but the <Enter> key does nothing.

The intent of placing the cursor at the beginning of the message is to add a line to the previously sent email.

The chosen option of 'edit as new message' should work with <Enter> regardless of where the cursor is positioned.

Any chance of this being addressed?

Thanks.

I am using ThunderBird 153.0 ESR for Linux Mint mint-001 - 1.0

Hello, I can't receive any of my e-mails. I can send e-mails out now. Plus I can put in my password to log into my e-mail. This has been a headache for me, I have been with Thunder Bird for years.

I also get a boxes that says : Unable to write the email to the mailbox. It says to make sure the file system allows me to write privileges, and I have enough disk space to copy the mailbox. I have enough space on my computer system and all. Another box that says my e-mail is being processed. Please wait until processing is complete to get messages. I did e-mail you yesterday on these issues. As I said I can e-mail messages out now also log into my e-mail with my password. Thanks, Chris

I have two domain accounts; crumpcorp.com and dannycrump.com with GoDaddy. I have two E-mail accounts; [redacted] @crumpcorp.com and [redacted] @dannycrump.com. I use Thunderbird desktop Email. Thunderbird has the ability of use filters to perform automatic actions on messages received. One of the filters is “Forward Message To”. Unfortunately, attempting to forward messages fails. Thunderbird displays the following message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

Please help with this issue.

On Saturday morning 27 June 2026 I tried to login my Orcon email account via Thunderbird (which I have been using for a long time). But my login didn't work, I got a message saying "login to POP3.orcon.net.nz with username habitation failed." On 30th June 2026 I reported the problem to Orcon.

Orcon gave me the following settings for Thunderbird. I have done that and even made a new account: Incoming Server Type: IMAP Mail Server: imap.orcon.net.nz Port: 143 SSL: Off Authentication: On (username and password required)

Outgoing SMTP Server: Mail Server: smtp.orcon.net.nz Port: 25 SSL: Off Authentication: Off

Since then I have spent many hours and going around in circles with Orcon's Technical Support to resolve this, but no luck. They blame Thunderbird. I used Thunderbird Troubleshoot Mode. The message that comes up reads: login to server mail orcon.net.nz with username habitation failed. Please can you check that your server settings above are correct? And if there is a bug? Irma

Our email comes through SaskTel. They are making changes and suggest that we contact any other platforms we use to confirm they support DMARC-compliant email sending and to see if any updates are needed. Please provide this information to me. Thank You.

A message failed to send due to some issue with the mail server, and Thunderbird said I could choose to Send Later, which I chose to do. But that message disappeared (to me) - wasn't in Drafts, where did it go? Thanks,

I use Thunderbird on my desktop and since early June, I have not been able to receive any new messages but I can still send. Everything works fine on webmail (Yahoo) and phone (Samsung Galaxy), it's just my desktop which is affected . I asked Duck AI about this and this is what I got...

I tried the solutions offered without success.

When I press the send icon in The Messaging Company email nothing happens. Therefore I cannot send emails. Have tried various port numbers in the outgoing server and secure connection is established.

I have just installed Thunderbird on a replacement computer (running Linux Mint). The version I have is 140.7.1esr. I use a POP Gmail account. For a change it installed and connected seamlessly, but I cannot persuade it to download anything other than the messages in my Inbox. I have right clicked as recommended on my Gmail address, but see no 'Subscribe' to select. What am I doing wrong?

Yesterday I found that I can't send mail using Yahoo.ca. I was able to get my wife's computer working by sending an email. A message came on the browser and I logged in to Yahoo. She can now send email. When I tried the same thing on my computer, I get a message "No apps available". I have spent hours trying and can't get around the message. The simplest test is as follows:

• create a new profile, and open the new profile
• enter my name and email address, and continue
• I get a message "Configuration found in Mozilla ISPDB." It uses SSL/TLS and Oauth2
• I hit next. Yahoo opens a page in my browser to log in. I enter the password and the security code sent by text
• The browser sends a message to allow an app. When I allow it the message "No apps available" appears as shown.

The release notes on Thunderbird are Version 153.0 | Released July 21, 2026 For now, I can use a second account on gmx.com to send mail, but prefer to use Yahoo when it works. Any suggestions?

I have smtp.gmail.com set up as my outgoing server (port 465, username = my gmail address, Authentication = OAuth2, connection security = SSL/TLS, also tried STARTTLS with port 587). There doesn't appear to be any way to set the password in the "Outgoing Server (SMTP) Settings", even when I click "Edit". Nor can I add a password to the "Edit/Privacy&Security/Saved Passwords" dialog box (which allows you to see existing passwords or remove them, but not add any).

When I try to send an email, the "Sending Message" dialog box pops up, and after a few seconds a second box pops labeled "Login to account 'smtp.gmai.com' failed". This box has three buttons: "Enter New Password", Cancel and Retry. Clicking on the "Enter New Password" button does not offer me the chance to enter a new password--instead, it immediately takes me back to the "Sending Message" box, which then immediately takes me back to the "Login...failed" box. There is never an opportunity to enter the password!

TBird 140.7.0esr, Thunderbird for Linux Mint. Mint version 22.3.

Sending works ok if I choose a different SMTP server.

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."
