Hello. I have been using Thunderbird for personal email on my desktop for some years now, but recently the client seems to download messages and then allow only a few for me to read. I don't think I have set up any SPAM or TRASH detection. Right now, in addition to my message downloads, the client is showing 3 messages as NOT READ - but which I cannot find to see! Is it something to do with the number of messages still sitting in my INBOX? I have around 3700 of them.

Just not sure how to solve this. I just tried to send a message from another of my email accounts - which was received and viewed fine. Attached is an image of my INBOX. Thanks for your kind help. Lee, West Sussex UK

Bug? Is there a fix coming. I move emails between different accounts all day long :)

As an intended workaround, I installed the beta version but the import of settings did not actually move over my configuration of views, toolbar settings, threading, etc. and that would take a quite some time setting up again.

I have a problems receiving and sending emails from and to externals users. However I don't have this problem with the emails receiving and sending between my coworkers (we have the same domain @spectratech.gr). We checked the SMTP settings (IMAP/POP3), SSL/TLS settings, updates and these setting seems to be ok. What could be the problem? thank you

Moin,

ich bin von Outlook umgestiegen auf Thunderbird, das lief soweit alles gut, dann wollte ich meine "alten" Ordner im neuen Programm anlegen habe dabei festgestellt dass Änderungen in Thunderbird ins Outlook übertragen wird, also ich ändere im neuen Ordner den Inhalt in Thunderbird ist die Änderung auch in Outlook ausgeführt, das ist sehr ärgerlich.

Ich bin mit der Bedienung von Thunderbird nicht so gut vertraut, das bedeutet wenn ich hier was ausprobiere hat das Auswirkungen auf die Daten im Outlook, in meinem Fall sind wichtige Unterlagen futsch.

Hello, Since tuesday (2025 february 25) I can no longer send e-mails from my main account, whoever is the recipient. As soon as I clic on "Send" I get the message below: "Sending of the message failed. An error occurred while sending mail. The mail server responded: : Client host rejected: Access denied. Please check the message recipient <recipient address>". I did not change anything. I have the exact same issue on an other computer with the same Linux distribution (Xubuntu 20.04, both up to date) running the same Thunderbird version (115.18.0). What is weird is that I have no trouble to send e-mails from a secondary account, on both computers. I checked using openssl that the problem is NOT related to the smtp server. Anyone experienced the same weird issue? Thanks in advance for any help. Lucie

Mail arrives in the Spam folder. It is not spam. I click on Mark and click on It is not Junk. Messages move to inbox. Perfect. Now why are later emails with same email address again sent to the spam folder? Once an email is declared as not junk/spam, it should be cleared to go to the inbox. Can this thought/idea be incorporated into the next update? Thank you. Greetings from North Germany. Ken Yeager

Following a switch off and restart triggered I think by a Windows update, Thunderbird is not displaying any messages in my Inbox, though it is showing the number of messages in the Inbox title bar. 'Drafts' and 'Sent' all display correctly, but the 'Inbox' is blank with a grey icon of an envelope and the statement: "No message found". I am an IT novice. I looked on the 'help' pages. I have checked that no filters are set. I have right-clicked on the 'Inbox' title to display the menu with 'properties' at the bottom. I have clicked on that to bring up the dialog box with the "Repair" icon. It shows 'Inbox' in the 'Name' box but I note that the 'Location' box is blank. Presumably it should not be. Presumably it should show either the location of locally stored messages on my hard drive, or the location of the messages on the email server. I am not sure which. I have found the directory on my hard drive where I believe the messages are stored locally. The size of the file suggests to me that they are all there. The periodic 'Checking for new messages' is happening, but nothing is displaying, though a check via webmail shows that new messages are arriving on the server. What should I do to get my Inbox to display correctly? With many thanks, Iain

It went away for a while but now it is back. When I select the text it usually (but not always) resolves. However it is a pain to keep stopping to do that.

I've tried the existing fixes but they either don't work or stop working after applied.

In composition, when I hit enter alone, it will have a double spaces instead of single space. The solution for that I can find in searching, so I can have a single space by using Shift + Enter keys. However, I could not find the permanent solution for that since I could not find the option which I can uncheck the box to turn off the double spaces by design. Please help. Thank you.

Hello there. On my previous email desktop app I was able to use my 'magic mouse' swipe features to quickly delete emails irrespective of even reading them first.

I have looked for this in the Thunderbird settings but I can't seem to find this option. Is it me? Or do you not have this?

Kind Regards,

James

Using TB 115.15. When I delete a number of messages, then empty the trash, I cannot delete another message until I restart Thunderbird. Is there a limit as to the number of emails I can trash prior to emptying the trash?

Hi All,

It's almost like I don't have connectivity to the Internet with Thunderbird when I have it with all other applications. Today, Thunderbird stopped working, sending and receiving email. For me that may be a good thing, given the number of junk mails I get but there are some important ones in there as well. I can see my mail if I directly to Comcast, but not Tbird. I also can't send email either. Has anyone woken up to this nightmare?

Regards,

Ernie

Hi All,

2 Days ago, I stopped receiving all emails into my 5 inboxes with Thunderbird on Windows 11 desktop.

Tried some troubleshhoting including updating to the latest version of Thunderbird version 128.7.1esr (64-bit) on desktop for Windows 11, and turning VPN off and on.

Would appreciate any troubleshooting ideas to get emails flowing again.

Thank you

My Thunderbird application is either deleting or hiding emails. So far, it appears to be emails I send and copy my self on. I included a BCC to my second email and still it disappeared.

I initially receive the emails, but once I exit Thunderbird, then later launch Thunderbird again, initially the email is present, then it disappears.

I have no idea what to do to correct this issue, if it is something I can correct.

I am running Thunderbird version 115.18.0 (64-bit), on Linux Mint Cinnamon 21.3

I hope there is a fix for this. I do not like seeing my emails disappearing before my eyes. This is a weird issue.

Thank you,

Clarence Hayes

I'm setting up TB for the first time. Have imported my contact list into TB from Google, but in my TB address list their email addresses are shown under Nicknames instead of Email addresses. Is there a way of changing this en bloc, please? Don't fancy having to click and drag them all across.
