Thunderbird — Fora społeczności

Somehow I got 2 emails: gregory@gregorysantana.com and Gregory@GregorySantana.com The lower case shows a lock blue envelope and the upper case shows a lock red envelope. I don't understand the icon meaning of the lock icon and the color coding.

Further: I use command File, sub menu Get New Messages for All Accounts.

In the lower part of the overall panel, I see new messages downloading, but the new messages don't show up in either account.

How to correct, it is important.

I succeeded in the Thunderbird transfer method described in these forums when bunging it on an old Win10 laptop. When I come to try the same on a new Win11 PC however, setting up an existing email address simply fails. I get as far, in the Set Up Your Existing Email Address page as "Configuration found at email provider" but can proceed no further as I get the message "Unable to log in at server. Probably wrong configuration, username or password" The setup on my old PC is gone now, it finally gave up the ghost, I have email on the old Win10 laptop but that's far from ideal. Additional facts: it's an ntlworld email address; there's a possibility the password may be redundant (so many of these to be found when a PC is on its last legs) How do I get it onto this Win11 PC?

I have a large number of filters, and an important email was processed to move message into a folder. but the filter had no rule that would apply to the message. all the filter criteria were based on the sender, but that email did not have that sender. the filter log shows the filter being applied anyway. I suspect the filter database is corrupted. How can I fix that? i noticed my version is slightly out of date, and I will update it, but I dont expect that would fix a corrupted filter database .

Hi! I am having an issue with displaying sent mails. As you can see in the screenshot (cropped for privacy), I have selected the option to "Place replies in the folder of the message being replied to", which to me means that eg. a reply I sent will both be shown in the "inbox" folder in the message thread, as well as in the "sent" folder. However, it only shows up in the "inbox" folder. Why does this not work?

Thanks!

I'm running the current version of Thunderbird on Windows 11 Pro. Several time in the last few weeks I have noticed periods where I don't seem to be getting mail. When I close Thunderbird and restart it I get batches of 10-20 email messages that had been delivered to my shaw mail account, but which Thunderbird hd stopped downloading. There were no obvious messages that it had failed.

Thunderbird stopped downloading gmail this morning. It worked fine yesterday. I've restarted it 3 times to no avail. It says "Connected to imap.googlemailcom..." and it's been saying that for 2 1/2 hours now. Please help.

And please respond in non-tech terms. I am an old lady and I don't understand any of the stuff in the "help" section of your website. Still running Win10 because I can't handle the learning curve to 11. Please and thank you.

Hi everyone!

I'm trying to log into my email account on the domain example.com via SMTP. The email account is with yandex.ru. When I try to authenticate, it says the SMTP password is incorrect. I decided to try through Outlook, and it worked. What could be the issue?

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.

Please respond to [redacted from community support forum] @dannycrump.com

My account setting correctly are set to store send mail in send of the account. Now: - Shoud be: a send mail goes always there - Is A send mail goes sometimes to the local send folder

Pleas, tel me how to corect that.

Kind Regards, Ruud

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

Hi!

I have configured a EWS email account that requires manual configuration (I need to pass the override Office365 settings with application ID, tenand ID,...). When I select manual config I can configure the EWS server settings OK and the receiving part works OK. The problem is the outgoing server is not created OK (it is imap with password setup). I need to use the same EWS to send the email, imap is not allowed in the account. And I cannot configure the account to use EWS as the outgoing server. The outgoing server cannot be EWS and I need to setup one. So I'm in a loop.

For what I have read, thunderbird can send the email using EWS (https://support.mozilla.org/en-US/kb/thunderbird-and-exchange), but my feeling is that using manual setup (which I need to do to configure this account) breaks something internally and the outgoing is separated from the EWS receiving part. And I cannot configure back to use the internal EWS configuration in the receiving server part.

Can I do something to send emails using the same EWS configuration? What does the automatic setup to use the EWS configuration? Is there any bug for this situation?

Thanks in advance!

I have 5 emails setup on Thunderbird. I can receive emails for all 5 accounts. However, I can't send email on any of the accounts. I went through some of the old threads and tried to adjust the outgoing server, but I haven't been successful. Typically, I get a message like attached.

Ich habe mehrere email Accounts auf denen ich Benachrichtigungen über email Eingänge erhalte. Auf einem email Konto klappt das nicht. Ich finde keine Lösung dafür.

Ich bitte um Hilfe
