Having opened Thunderbird a message came up to the effect that the folder had not loaded. No emails were shown in the list, although the total number of emails in the folder appeared as usual above the list.

Thunderbird then downloaded over 100 emails, according to the status bar. These messages were previously present on the server, and were downloaded via POP3 with the option to delete on the server once downloaded selected.

Having closed Thunderbird and relaunched, the folder with all the existing emails appeared. However, there are no emails now on the server, this having been verified by logging in to webmail.

Where have the emails gone?

If they are indeed lost then why does Thunderbird proceed with downloading messages when a folder has not loaded? Why is downloading of messages not conditional on the folder having loaded? This would avoid such an eventuality.

I am running Thunderbird 115.18.0 32-bit in Windows 7 SP1 64-bit.

Hi all,

I’m having trouble with Thunderbird where emails I send don’t show up in the Sent folder. I use a Gmail account via IMAP.

Details: •⁠ ⁠When I send an email, it doesn’t appear in the Sent folder in Thunderbird - sometimes it does thou. •⁠ ⁠Sometimes sent emails don’t appear even in Gmail’s web Sent folder. •⁠ ⁠I have checked my account settings, and the Sent folder is mapped correctly. •⁠ ⁠I use Thunderbird version: Version 140.0esr on Sequoia 15.5. •⁠ ⁠I don’t see an Outbox folder in Thunderbird. •⁠ ⁠Sometimes I get errors related to folder sync (like “folder in use” message).

What I tried: •⁠ ⁠Restarted Thunderbird •⁠ ⁠Checked folder subscriptions and synchronization •⁠ ⁠Verified Gmail IMAP settings •⁠ ⁠Sent test emails to other accounts — same issue persists

I’d appreciate any tips on how to ensure sent emails are saved and visible in Thunderbird’s Sent folder and on Gmail!

thanks

On one of my email accounts when I start a new email message the page fills with this - -- PK?????!?A�.f?T????[Content_Types].xml �??(�?���n�0?E���?�� �tQUUH?},�HM?��?��/����;@��(?�I6H0s�=?xF��V� |���d� H?�[!M����[�H�?�?LY?9�B ����h�u??T���E����?�YȬ?���z�"���:�X �~0x�ܚ?&��� ��??l�b��� ɷ��$�Mc��?�+��@�j<�p�a�)�Y�:]?q@��2T�=a!]�Æ����?��}���R@2e>�3�]tm����Fev��?�- ɡ�Wn�[?!�w�*k+�I����?q� \���폇?Qp ��s/�?�W��c�?R`��?\?��xj��?��mNEb��[?p?���?��:Ł?�(O�um"Z�=?T�@�8�M�8�?��?PK?????!?�?��N????_rels/.rels �??(�?���j�0?@���ѽQ��?�N/c��?�??[IL?��j���<��?]�aG��ӓ�zs�Fu��]�?�U �� ��^�[��x����1x�p�?���f��#I)ʃ�Y?��??������?�*D��?i")��c$���qU���~3��1��jH[{?�=E��?��?~

bonsoir, depuis quelques mois je ne peux plus envoyer de mails avec thunderbird, orange m'assure que le serveur SMTP est fontionnel. merci de votre aide. Marie Bordet

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!

I am unable to send an original email right now with Thunderbird. I realize "original" is not the best descriptor but what I am trying to describe is if I compose an email to another party, Thunderbird tries to send it and immediately returns the message below even if I send the word Test in the subject line and as the one word text message:

Send Message Error Sending of the Message failed An error occurred while sending email. the mail server respnded: [VO-1] Message blocked due to spam content in the message. Please check the messge and try again.

I have tried multiple email recipients with the same results.

However, if I take an email currently in my Inbox and Forward it to another recipient, it sends it with no error.

Thanks for your help. I am sure I have done something I should not have but I cannot think of what it was.

My Thunderbird email works fine except when trying to send emails to someone with an Outlook account. The emails keep bouncing back undelivered.

Any ideas please

• every time I send a msg in Android the msg gets sent but there's duplicate Compose window behind it that has to be closed... using version 10.0 ... please advise - thanks

A few months ago I got the problem that when trying to send via gmail this is rejected with the message that the connection with the SMTP-server takes too long. What can be the reason for?

I am receiving emails but can't forward on an email or send a new email. The message that comes up on screen says "sender rejected. Please verify that your email address is correct in your account settings and try again". My email address is mryankillavalla@eircom.net
