Att made me change my account password. Now Thunderbird cannot access messages. I have entered the new password in out going and incoming but there seems to be more to this than that because nothing happens. Where do I have to put in new passwords? Thanks so much. Marjorie

in the last couple of days thunderbird has stopped showing emails from one particular account. Inbox is only showing messages up to yesterday, and all mail is only showing to the day before (?). The messages are on the proton webmail inbox ok, and are received by the proton mail app on my phone. I have not changed any settings, and it worked perfectly before now

My windows 11 computer stopped accessing yahoo mail. I get message

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

I have tons of space.

I have had Thunderbird on my HP laptop for several years. Everything has worked perfectly. BUT, I cannot receive Email, starting yesterday. When I click the Get Email icon, nothing happens. My Email server on Comcast is getting Email which I can see and read, but Thunderbird is not getting the Email. I would appreciate any advice.

Regards, Jim

Thunderbird upgraded itself to version 140.2.0esr (64-bit). I also got a new browser tab for Thunderbird 140 Eclipse. However, now Thunderbird will not receive any new emails. I can see that they're out there via my mobile phone. I don't get any kind of message when I try to receive emails. It's as if it's totally ignoring my request. I have two email addresses - it will not work for either.

Additionally, I am able to send emails out to a gmail address. So the only issue seems to be receiving emails.

Specs: - I have a Windows 11 laptop. - I'm using POP3 (I know, my friends are giving me crap. But I want to keep my emails on my laptop, not on the server. I'm old school that way.).

I've tried requesting emails the following ways: - Hit F5 - Click on File | Get New Messages for | All accounts - Click on File | Get New Messages for | Current account - Click on File | Get New Messages for | <choose the individual account>

I've tried the following to resolve the issue, without success: - I saw online where someone mentioned a bug with the new version. They suggested creating a default account. I already had a default account, but changed it in hopes that it would help. However, it didn't. - I deleted the global-messages-db.sqlite file to try to rebuild the profile (this was also suggested online). The rebuild was successful, but I still could not receive emails.

Can you help me? Thanks very much!

Hello How do I un-Blacklist myself?

I- the Sender - has been Blacklisted. I can't send out Emails because of this. I can't even upload a screenshot of the message I got about this.

I use a Windows 10 Desktop.

Regards, Catherine

Recently, my SENT file has not been keeping the email I send. Has anyone else had this problem? Can anyone suggest how or why this has started happening?

I count on being able to look and see that I have sent or replied.

Thanks for any help, Jerry

I am on W11 home. Tbird user for maybe 10 years. Just updated to 140.0.1. The New Message button does not respond to anything -- left, right mouse, alt control shift buttons. zip.

I went to use Thunderbird mail on my laptop for the first time in ages. I can receive emails but they won't send:

Log in to server SMTP-mail.outlook.com with username x failed Retry - Enter New Password - Cancel

- I entered the current password, which works fine for Thunderbird Mail on my desktop PC, and checked the box use password manager.

Send Message Error: Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp-mail.outlook.com Please check the password and verify the 'Authentication method' in Account Settings | Outgoing server (SMTP)

Server Type: IMAP Mail Server Server Name: imap-mail.outlook.com I CHANGED THIS to outlook.office365.com - to match the server settings on Thunderbird Mail for my desktop PC - and restarted Thunderbird, but the Log in to server failed message displayed again. Port: 993 Default: 993 Connection security: SSL/TLS Authentication method: OAuth2

I trust I have provided sufficient information for you help me. Thank you!

Hello, Mi 9 SE with MIUI 12.5.1 Android 11 RKQ1.200826.002 Thunderbird 10.0

I moved from K9 to Thunderbird some time ago without incident. In the last few days I realised I had received nothing and checked on my PC and indeed mails were waiting. I tried to send a test mail from the phone, the mail remained in the OUTBOX and I received the following error message :- "Failed to send some messages ErrnoException: connect failed: EACCES (permission denied)" I checked and this is an Android error and various articles I found that suggest necessary changes to the manifest which I am not capable to change; I am not a coder. I decided to save the configuration, delete and reinstall Thunderbird. After this and reapplying the passwords the waiting mails were delivered. I then tried to send a test message from the phone and again the same error was generated with the phone blocked again from sending or receiving.

I suspect that there was an upgrade applied with a changed manifest that broke the operation of Thunderbird with Android 11.

Can someone please verify this, it may be impacting many installations on older phones?

Many thanks!

Thanx for initial reply to my help request ...

My problem with Thunderbird downloading my Yahoo.com e-mails continue.

I've changed Yahoo.com passwords in the past with no problems. Thunderbird seems to have changed & become more complicated. I can't find the app password Generator for Thunderbird, but I'm able to see my Yahoo Password & the Oauth2 security protocol etc

So how in the heck can I get Thunderbird to work properly? And download my my messages into TB as it has done for years.
