I have two accounts, wbob@optusnet.com.au & OPTUSNET, which I have using for many years. A few days ago the Sent emails not showing in Sent Items folder in both accounts. I have consulted Chatptg, and played around in the ☰ Menu → Account Settings → your email account → Copies & Folders. Many test emails to my self and I think I have made it worst. I hope you can help me PS. I don't like the two account arrangement, back & forth checking inbox every day. Thank you Bob

Today Thunderbird will not download emails. Yesterday no problem downloading emails.

Windows 10. Thunderbird 153.3.1esr (32-bit) Email is POP3. AV is Malbytesware. I added what I think is the Thunderbird folder to exclusions ("Allow" in Malbytesware). I deleted the global-messages-db.sqlite file. Thunderbird recreated it, but the problem persists. I disabled Malbytesware and still cannot download emails.

Plenty of empty space on my C: drive where Thunderbird lives.

To the best of my knowledge, folder privileges have not changed today from yesterday.

Running Thunderbird as an Administrator does not fix the problem.

I need help to fix this. Please, if you have a suggestion, give me a few "click this..." steps so that I can follow you kind advice without having to come back and ask you again, "How do I do that...?"

Hello, I face a problem with my email provider. I received an email and I can see 2 dates-hours in the emails platform of my provider (coprmail Cosmote, Athens, Greece). Specifically, 111:24 am and 12:06 pm. In Thunderbird, for the same email account, the column Date shows the value 12:06 pm. This caused other problem. In search I made, in the emails platform of my provider, for the same email, I have 11:24 am and in the preview window of the body of the email shows 12:06 pm. In my question to the provider, why this happened, I received the answer that the message received at their email server at 11:24 am, and the other date, 12:06 pm is the hour that the sender sent the email. I can understand that the PC of the sender could had wrong date+hour, but what is happend with thunderbird? So, my question to the community is: In the table list of emails in Thunderbird, the column Date what does it mean? I am waiting for receiving your reply. Yours sincerely Panagiotis Sousounis Region Of Attica Athens Greece

Hi, I'm using Thunderbird for Yahoo Emails since many years (it's great!).

In March/April 2026 I changed the Server Settings (authent. method) to OAuth2, it has worked properly.

But since 23.9.2026 I cannot receive Emails in Thunderbird any more (only for the Yahoo account, I have another Email Account working properly in Thunderbird). Bottom text is "Message 1 of 33 will be downloaded", but nothing is downloaded after severals minutes.

My Yahoo Account in the Firefox Browser works properly, its ONLY Thunderbird (and probably OAuth2?). I have removed my Oauth2 Password in saved password of Thunderbird and generated a new one, but that does not help.

So if this issue cannot be solved, I will use another Email Program instead of Thunderbird!

Kind regards Soenke

This issue has existed for a while now. I keep receiving this message on my screen when I send an email from StartMail ( see attached )

This issue does not occur with other providers when using the same client to send emails.

It happens on different computers that has a newly installed operating system and a fresh installation of Thunderbird. The issue is only with the sent folder and only for this email account.


I taken multiple steps to correct this.


Tried installing Thunderbird on a fresh operating system installation and the issues persit

Account Settings -> Copies & Folders. I have tried both Sent and Other.

IMAP is properly configured to imap.startmail.com port 993. This should not matter because the issue is only to the sent folder.

Sent folder set to Syncronized

Sent messages not going into a different folder by mistakes because of any filter.

Properties Repair Folder done

Inside the profile folder under IMAP imap.startmail.com deleted Sent.msf, Sent messages, Sent messages.msf

Click on get messages



.......If I sent an email from the startMail web interface then the email is saved to the Sent Messages but the counter does not show there is a new email

Again the issue only affects mt Startmail account sent folder. All the other accounts do not have issues.

There is a messages that keep re appearing on my screen. Is this helpful ?

The current command did not succeed. The mail server for account ........@startmail.com responded: [TRYCREATE] Mailbox doesn't exist: Sent (0.001 + 0.000 secs ).

What gives I have both a sent and a sent messages folder but no messages are saved and if I am reading this right is telling me that the folder I have does not exist ?

Also I am using Linux Mint 22.1 Cinnamon


A few hours after my initial post I tried another client. Evolution client was configured and worked out of the box. There was no issues with emails being placed in the sent folder.


Is Thunderbird broken ?


I appreciate any help to correct this please. Thanks
