Thunderbird Community Forum

I have Thunderbird installed on a desktop and laptop (both running Windows 11) and an Android phone. I can no longer receive emails on the two PCs, though the phone still works OK. Webmail works fine on all three devices. I have tried all the remedies I can find on the web, but so far without success. When I send a test email to myself it goes out OK and appears in my webmail, but does not appear in my Sent box. I tried doing Repair Folder on my desktop Inbox. This caused all the existing messages in the inbox to disappear, though the folder size still shows as 400Mb. I have a secondary email address which I use occasionally (a gmail address). This is still working OK. All help gratefully received. Alan

I have Proton Mail, and Proton Bridge. It was working until Yesterday. Starting Yesterday, New emails would show up in the Web app, and the ProtonMail Desktop App, but would not make it to the Thunderbird Inbox. The first email that did this arrived at 1:30PM on 10/19. When a new email arrives, a new email windows notification will popup in the lower right hand corner. I checked Spam, and it is empty (I find this hard to believe). My phone also displays a new mail notification.

I know Thunderbird is receiving the emails. I can find the new emails by using "Quick Search", and searching for the email address of the sender of the new email. The results are completely without formatting, and do not indicate what folder they are in.

For example: I have a Gmail Account (redacted@Gmail.com), and I sent a test message to my ProtonMail address (redacted@Proton.me). That email contained the subject line "Ping 10/20" and it contained my auto signature. If enter "redacted@gmail.com" into the quick search, and I hit the return button, it only finds a message I sent about 7 weeks ago.

If I then click on the magnifying glass icon, a new tab opens up with the results. It displays the first 10 results of 54 results searching for "redacted@gmail.com". At the top of the results is my "Ping 10/20" test email. I could not find the folder name where my "Ping 10/20" test email is located on this results tab.

I see that the text "Ping 10/20" is a hyperlink, so I click it. The tab shows up, and strangely, it show the email and one reply. No reply was received by the Gmail account.

I have done troubleshooting of the ProtonMail bridge. The fact that the email is found somewhere in my thunderbird installation, I don't think ProtonMail Bridge is the issue.

Today when trying to send an email I get Sending of message failed. The mail server responded: Mailbox full. I use an Outlook address. I have emptied my trash, spam, and sent items folders along with moving many of the contents of my folders to the Local folders.

I tried the automated setting up - several times but get the error message below, I tried changing the authentication but same result.

I tried the Help here: https://support.mozilla.org/en-US/kb/thunderbird-and-hotmail - but it didn't help!

I have the settings it shows for Outlook - but it doesn't work! When I "Continue" I get Authentication error. Show less

"Unable to log in at server. Probably wrong configuration, username or password.". It hasn't asked for a password.

I can login in to Outlook webmail and receive messages. Please help. I'm not overly technical but not totally ignorant either! Thanks, Isobel

I stopped getting e mails 9 days ago on Thunderbird. I found out that plusnet that used to have me had passed on to greenby. I can get onto greenby but i would prefer to be on Thunderbird because of my saved business e mails. Mike

So long as I investigated, the problem is,

After version154, received emails in Japanese encoded by 8bit causes misconversion (mojibake). Emails encoded by base64 is not misconverted. Only 8bit encoded shows the problem. Version153.5 is no problem. Version154 and newer shows the problem.

Here are OK/NG by sender/receiver combination. Sender version154 8bit - receiver version154 - NG Sender version154 base64 - receiver version154 - OK Sender version154 8bit - receiver version153 - OK Sender version154 base64 - receiver version153 - OK Sender version153 8bit - receiver version154 - OK Sender version153 base64 - receiver version154 - OK

Emails encoded by base64 is OK, but some senders can encode by only 8bit. I cannot find how they can use base64. It would be helpful to know to use base64 encoding in version154 (or later).

However, the best way is that version154 (or later) can read 8bit encoded email in Japanese. I would like to thank anyone who help the problem.

After today's update, my email is not loading from Gmail. Last delivery was 5 a.m. It is now after 5 p.m.I have restarted Thunderbird 3 times, restarted my computer and restarted the modem to no avail.

Hello This is a Thunderbird on Windows 11 question If I select a file, right click and then click on "Send to" >"Mail Recipient", Windows tell me

There is no email program associated to perform the requested action. Please install an email program or, if one is already installed, create an association in the Default Programs control panel.

But Thunderbird is installed, up and running and is set as default for MAILTO (see image)

So what could be the problem?

Luckily, files can be loaded into messages using the "Attach" command in Thunderbird if that gives you a clue

Thanks in advance for any help

Hi

"I am being asked daily for my pop3 password

Login to server pop3.tpg.com.au with username ##### failed. retry, enter new password, cancel"

Each time I enter the password and my mail rolls through. I have the password saved using the password manager and I can see that the correct password is saved. 
What do I do to stop this happening each day? This has only been happening since the last windows update so maybe a clue there

Any assistance will be very much appreciated

Unable to open the summary file for Sent on xxxx@gmail.com. Perhaps there was an error on disk, or the full path is too long. I have tried to connect my second gmail account. The first one went ok. With the 2nd on the Inbox and All Mail folders initially gave this error, but Repair fixed both, Sent and all other folders have this error and Repair no longer fixes the problem. Then I noticed that I was then unable to delete emails from 2 inboxes including Thundermail inbox.

I am currently unable to send emails. I am getting a error message saying: Connection refused - OB116. 159.196.15.181 is blacklisted in Abusix Mail Intelligence. I can receive emails but not send them.

Hi - We are receiving this email when sending to live.co.uk and hotmail.co.uk email addresses from one of our emails but not our other domain emails

550 5.7.1 Unfortunately, messages from [91.238.162.49] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3140)

I can't see any difference in the account settings and wondered if anyone could help?

My e-mail is zamaaero@zamaaero.com. But since today I can not sent any mails. Message is: "Slanje poruke nije uspjelo. Greška prilikom slanja pošte. Poslužitelj je odgovorio: SMTP AUTH is required for message submission on port 465. Provjerite primatelja pošte "zgmazoretkinje@gmail.com" i pokušajte ponovno". And that is for each and every adress I try to send.

I recently set up Thunderbird for Windows as a troubleshooting step for my Yahoo Mail account which has been generating an incessant number of authentication pop-ups in Microsoft Outlook (Classic) for Windows. I had been using New Outlook for many months before switching to Classic Outlook a couple of weeks ago. With New Outlook, there had been no authentication issues nor pop-ups appearing. I have been using the OAuth authentication, not app passwords, in all cases.

Setup within Thunderbird was relatively easy and the OAuth authentication went through without issues. The account has synchronized and seems to be continuing to do so as I read, delete, and send messages.

However, when I went in to the Activity Manager, I'm seeing a number of errors, appearing every 10-15 minutes or so. They read as follows:

• Alert from account xxx@yahoo.com: AUTHENTICATE Server error - Please try again later

• The current operation on 'Inbox' did not succeed. The mail server for account xxx@yahoo.com responded: UID FETCH completed.

• The current operation on 'Inbox' did not succeed. The mail server for account xxx@yahoo.com responded: p.

Can anyone help me understand what they mean? It would help me stabilize Thunderbird and might give some clues as to what is happening in Outlook Classic for me. It would seem some have authentication issues with Yahoo on different platforms while the service works perfectly fine for others. I would like to move away from Yahoo as I find it finicky with a number of its features, but I'm a long-term user (25+ years) and don't see that being a practical solution at the moment.

Thanks!

Sometimes when I go to my inbox it says "no new messages", when I have several hundred. and sometimes in the Send Folder too. I have to click on "All Mail" to see them. Does this happen to anyone else? What can I do to change this?
