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

I made a mistake. I had 128 and went up to 140. It pretty much looks the same, but a big difference is an extension I always use says it will not work with 140. I don't care how good 140 might be; if I can't use my app, QUICKTEXT, then I don't need this. How do I go back to 128 or to a version that works with my extension?

I exported up my Thunderbird data to an external hard drive from my PC in Croatia which I have been using there for the past year.

I am in South Africa now for a few months and imported the data to my laptop with a new Thunderbird installation.

I have 5 email accounts on one domain, and 1 on another domain.

When I checked for new mail, I was asked for passwords for the 5 accounts on the one domain, and after entering this, the new emails came through fine.

However the one email account on the other domain did not ask for a password, and when I connect I get a message: "Connection to server xxx@xxx.com was reset" I can send emails with this account, but cannot receive any.

Interestingly, I have a previous installation on a desktop PC here in South Africa with the same email accounts. I tried that specific email account and it connects perfectly. The settings are exactly the same.

How do I solve this on my laptop?

For the last several days, if I get an email with a link to open in a browser (e.g. a tracking number, and Amazon order, Ticketmaster order), clicking on it doesn't bring it up in my browser (Firefox). It shows a blank window.

I have the latest versions of Thunderbird and Firefox, with the current Windows 11.

How can I fix this problem?

There were prob 20 or so, but now just blank tabs. My In Box and incoming email still show OK and I can read those in a new tab. but what about the old ones? And if I cannot recover, how can I remove those blank tabs. Deleting the usual way does not work.

On Windows 10. I wonder if Co Pilot has something to do with it

Thanks Tealeaf

I just updated to version 140.0 and now my subfolders are out of order. Is there a fix for this, short of fixing it manually? I miss how they were automatically alphabetized. That went away when manual reordering was implemented. I can't grab a bunch at the same time and move them, since the order is so messed up.

I cannot deliver emails with attached images. This has only started being a problem with upgrade to Win 11 64 bit 24H2. The message shows up in sent with the image.

I have a Suddenlink.net email account that I can't seem to install. Suddenlink has been purchased by Optimum. I have all the requirements that Optimum has given, but it still won't load. my email address is dluenser@suddenlink.net. My password is correct because I can go to their site and get my emails. These are the requirements that they gave me. Again, it is a suddenlink account. Can you help? I've tried numerous times to work with Optimum techs, but they are not knowledgeable to what I should do.

Server Settings by Domain Use the following server settings to set up most third-party email clients or applications to send or receive Optimum email. IMAP (Inbound) Optimum incoming mail server: mail.optimum.net Suddenlink incoming mail server: imap.suddenlink.net Incoming mail port (SSL): 993 (Secure Connection. Recommended if your mail client supports) POP (Inbound) Optimum incoming mail server: mail.optimum.net Suddenlink incoming mail server: pop.suddenlink.net Incoming mail port (SSL): 995 (Secure Connection. Recommended if your mail client supports)

SMTP (Outbound) Optimum outgoing mail server: mail.optimum.net Suddenlink outgoing mail server: smtp.suddenlink.net Outgoing mail port (SSL): 465 (Secure Connection. Recommended if your mail client supports) • Check My SMTP server requires authentication Username and Password (if needed) User Name: Your full email address, including the @domain.net at the end (i.e. @optimum.net, @suddenlink.net) Password: The password for your particular email address • Outgoing server verification/authentication must be enabled and on. If your email client has the option or checkbox that says My outgoing server requires authentication this will need to be checked along with use same settings as my incoming mail server.

While looking for another setting, I noticed that a setting about how T-Bird handles spam mail. I have it checked. Today, I received a DOOZY of a spam mail, but Thunderbird didn't flag it. It was so obvious spam, as it asked for credit card, banking, automobile license! Also, the Subject asked to update payment info, but the From field wasn't that company.

Hi guys. It used to be that when I read an email and click the delete button, the tab would close and it would return to the folder the email was in. But since the last update, it just shows me the next email in the folder.

Is there a way to change that? I want to return to the folder after an email was deleted. I don't want to look at the next email.

I looked in settings everywhere and if there is a way to change that in settings, I can't find it.

Thank you so much in advance for your help.

I was running TB 128.11.1esr up until 10:00 this morning on Windows 10 Professional 22H2 64-bit. I have some e-mail messages that I cannot delete. This morning I auto-upgraded to 1o 128.12.0esr and then to 140.0esr. I still cannot delete the messages When I try to delete a group of messages (containing the message in question), the messages in the in-box turn from black to gray, and I see at the bottom "Moving messages to Trash". But nothing happens. I did a "Compact folders", and it completed without any error messages. I can look at my Trash folder, and the contents seem to be intact. In one case, I individually deleted all of the messages except one. With this one, I open the message and see nothing in the bottom message content pane. When I do a "cntl-u" to see the RFC 5322 message headers, I see a window that is completely blank. What is happening, and how can I debug this? Thanks.

Thunderbird ver 140.0 (64-bit) on Windows 11.

Brand new, fresh installation of Thunderbird. - Added a GMail account. That worked. - I tried to add an account with my personal domain. I enter my name, the email account, and Thunderbird gets stuck in an unending loop looking up the configuration. - Other email clients have successfully looked up the config and did the setup without a problem. - The email account is handled via IONOS.com servers. - If you gave me a manual setup option I could handle it but there is none; TB goes straight into trying to handle it itself.

Any ideas?

TY, Frank

I am currently running Thunderbird version 140.0.4 [aarch64] on Windows 11 and no matter what I try I cannot stop emails from ebay@ebay.com from going into the spam folder. I have entered the address in all the address books, marked emails as not junk, and also set up a message rule/filter but to no avail. This is very annoying, can anyone suggest what I can try next ?

I was following instructions for the problem of some task bar icons showing as grey boxes. Still have that problem plus added the problem that thunderbird launches with the setup accounts dialogue page. The 'help>troubleshooting information>profile file location' reveals the correct profiles that have been updated to the hour before I caused the problem. I have saved the '...roaming/thunderbird folder to an external SSD, and made a new new thunderbird installation following the instructions for moving files to a new computer. Problem persists. Thunderbird will not 'see' the profiles therefore I cannot see my emails.
