Bonjour, La copie des messages envoyés n'apparait pas toujours dans le dossier des messages envoyés. C'est très gênant, comment faire pour rétablir la situation? Je voudrai avoir en copie TOUS les messages envoyés. MERCI

I've received the following message the last few days when I send an email with Thunderbird:

Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. (I am sure neither of those errors apply.)

It then gave me the option to "save" (I didn't get the exact wording before I clicked on "save") and I don't see it anywhere. This was a very important email and I need to find it.

I have been using thunderbird for years, Spectrum recently made changes and now I cannot get my emails. My email address has not changed. I have allowed thunderbird to set up email and I have manually configured the settings per TWC, and thunderbird. I have confirmed the connection but still no new emails are coming in. Any help would be greatly appreciated. Thank you.

Using Thunderbird 115.18.0esr Supernova 64-bit on Mac laptop OS 10.13.6. Worked fine for years, with ongoing Thunderbird updates, even though Mac OS is 32-bit. Suddenly, after 10/6/26 can't retrieve emails although I can see them on the ATT Yahoo server website. Can still send emails with Thunderbird. Inbound server settings are: POP server inbound.att.net, Port 995, SSL/TLS, Normal Password (I long ago created a Secure Mail Key, and even tried creating a new one). But inbound server name doesn't show in Saved Passwords (only outbound server with Secure Mail Key as password)? I have tried everything suggested, repaired my inbox folder, updated Thunderbird files, etc. in Profile as recommended. But still no prompt for password when attempting to get messages. Just shows "Done" at bottom left with no new messages received. But new messages are seen on server website. So it appears that Thunderbird isn't able to connect to the ATT Yahoo server to get emails. Why? And what else can I do? I love Thunderbird and want to continue using it.

today all my incoming emails are going into my Local deleted folder for some reason and trying to put them where they belong in the inbox simpy means they go straight back to this deleted folder, I have tried to look at the settings but cannot see why it is doing this. Thank you for any help regards Paul

I use Thunderbird with a info@... account hosted by TransIP.

When I send an email, especially when I reply to a previous email and even more when this was my own email, the sent email is not always saved in the Sent folder: neither in the webmail of TransIP nor in Thunderbird. It seems random when emails are and are not saved in the Sent folder.

The replies are sent through; the recipient receives them.

What can I do?

I am running Thunderbird 140.7.1esr (64 bit) running on Ubuntu 22.04.

I need to filter some emails, and need to filter by the "reply to" email.

Reading elsewhere, I followed the instructions, and created a new custom tag to filter (and checked in the advanced part of the settings, and saw that under the mailnews.xxxx there was the "Reply-To" header set up.

I then set up a filter to use this new tag (sorry if my terminology is incorrect), and ran it on a mailbox, where I know there are emails with the Reply To email address is present, and not one of the emails was affected by the filter.

What am I doing wrong?

Many thanks for your help.

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.

The email from ALL of my other active accounts (7 or 8 of them) all download fine.

Only ONE account throws off the Unable to Write Email to the Mailbox!

I have rebooted, I have compacted folders, I have repaired the folder - same result. Only ONE of my numerous emails fails to download messages.

ALL of the email databases are in the same subdirectory that Thunderbird (obviously) has complete read/write access to.

What now???

Not sure where/how to post this, so starting here (and happy to move/amend this posting as appropriate.) 15-Oct-2026

Background: I've got a yahoo ("free") email account for many years, and wish to move the current contents of my Inbox to a folder (on imap, not local). Recently yahoo appears to have moved to "cloud" arrangement internally (not sure, but it appears to be the case.) The problem I'm experiencing (below) I believe may be yahoo's back-end cloud processes getting out of sync with Thunderbird's view of the same activity. Therefore, I'm seeking help on how to accomplish this (=I don't think there is a bug in Thunderbird, rather this is a plea for how to manage yahoo's email service for my account.)

Symptom: Moving large number of emails between folders both hosted on yahoo, peers to my inbox on yahoo, using imap - the "export" imap service). Thunderbird says it completes the task, but many (not all) of the moved emails re-appear in yahoo's inbox after a short time, so this makes moving a large (more than a few hundred) emails a *very* laborious process.

What I'm trying to do: I wish to move my current inbox (has about 7.5K messages) to an IMAP-hosted folder (same account, etc.,yahoo email would see this folder as a peer to inbox). When I select all of the messages on inbox and tell Thunderbird to move these to the local folder, thunderbird appears to indicate the task was completed. If I move a very small number of emails at a time, that does complete successfully (=thunderbird says task completed, and the moved emails do not re-appear in yahoo inbox.)

Thanks for looking at this (long) posting and (particular to moderators) if I've posted this incorrectly or in wrong place, please assist!

Despite my attempts to find an error in my outbound mail settings, I keep getting the message below.

The test of the connection to the server passes everytime, but the mail form will not allow mail to be sent.

It's the ESR version. It all started when I added a vcard to my outbound mail.

"Sending of the message failed. An error occurred while sending mail. The mail server responded: Sender refused. Please verify that your email address is correct in your account settings and try again."

I'm not getting my emails. When i try to sync, it just blinks. I use the latest version on my Samsung S24 note ultra. I've thoroughly enjoyed Thunderbird except for this intermittent issue. I've cleared my cache. I've gotten out of Thunderbird many times and restarted it. Still no new emails or syncing.

When I try to send out an email, I receive an error message that states, Sending of message failed. An error occurred while sending mail. The mail server responded: <cjmst61@charternet> sender rejected. Please verify that your email address is correct in your account settings and try again. I have checked my settings and still can't send

When I send an email with my HTML file signature Thunderbird appends a text signature as well. The text signature is not visible in the draft email, and is not in the settings. The text signature is added for separate identity with no signature enabled. I want to stop this. Any ideas please?
