I-Thunderbird Community Forum

On my iMac, across all thunderbird email accounts, when I click on "New Message", the new window opens up with the Send button and Encrypt button blanked out. To activate the Send button, I have to right click on the Send button, then click on "Customize..." button, then click on "Restore Default Set". Next new message, same drill. This started one day ago and is a pain in the butt. How do I make the Send button live permanently?

I changed my password for Greenby/Plusnet today. Now Thunderbird is unable to connect to them. The password is correct as I can enter website directly. No problems before change. Grateful for help.

Should I reinstall?

How to filter all incoming emails to copy to another folder?

Filter has no "on incoming" criteria, only

Subject
From
Date
Size

I want "upon arrival", copy to ... Archive will probably do.

Alternatively, is there a setting for ALL Subjects, ALL Froms, ALL Dates, ALL sizes?

Thanks.

A "send later" button came up one morning instead of the usual "send" button. When I clicked on the write button to see where the "send" button was, several choices came up but when I clicked on the "write" choice I lost the other choices and now can't get back to the original write button and still no "send" button appears anywhere on the menu. I can save messages to Draft but still can't actually send them. I can still receive emails, just can't send them! Help!

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.

Moin, Moin nach Anlage von zwei neuen Filtern landet mein gesamter Posteingang im Papierkorb. Neuinstallation erfolgt. Foto siehe unten Windows 11 Neuinstallation heute

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?
