Thunderbird Community Forum

I moved some emails to a folder and they are not there. Tried to move last email to folder and it jumps back to my inbox. Also how do I access help in thunderbird?

For some strange reason, I have one message in my inbox that does not display in the window below it (just a blank window) and the message subject line can not be deleted at all. Message title has been there for a week now, shows up every time I start Thunderbird but it can not be displayed or deleted. I have received, read and deleted dozens of message since, it just remains as if haunting the app in defiance of any common sense at all. How do I delete it?

The image shows the message selected and the blank window below, once I select another message and then go back to this rouge message, the previous messages window remains, the blank window does not come back up, Indicated to me that there is nothing in this rouge window to be displayed, hence it is blank if the first message selected.

As of Oct 12 2026 I also have this issue. About a week before the 12th I was getting messages that I needed to sign into my RCN account which I would do and it just kept asking me. A few times each night to start then right before it shut me out I had over 50 of these messages just flooding my screen. I never did get a screen shot of that message, but did for the 2 error messages I got later once it shut me out. I shut down my computer the night of the 11th then when I signed back in on the 12th I could not send or recieve any emails. SOmething similar had happened before, but when I shut down again it went away. This time it did not. I then tried to access my emails thru the webmail I can access, but that also had shut me out. I also tried my tablet, a borrowed smart phone, but I could not access anything for my emails. I troubleshooted with my email company and my internet company, but they found nothing. Then I shut off the wi-fi on the smart phone and bin go I could access the webmail. But I still cannot find anything on what to do to fix this. I use RCN for my email, Spectrum for my internet. It is a POP3. Running Thunderbird version 153.5 Oesr (32 bit) Meadow, which says it is up to date. I have norton 360 anti virus & do not use VPN. I disabled my Auto-protect and firewall on the Norton and that did not change anything. I have sent the error messages to RCN and also troubleshot with Microsoft and had some hints, but nothing has come of that yet. Here are the screen shots of the only 2 things I ould capture. The error message was when I was trying to access my email thru Thunderbird. And it came up every time I tried to send messages, not that does not show up anymore and nothing happens when I try and send anything. The second one was when I was trying to access the RCN webmail and it would not let me in on anything I used. Until I shout off the WI-Fi. Then the smart phone could access my webmail account.

I get "connection to server pop.mail.yahoo.com timed out" every few minutes. mail is not usually delivered, and some mail that's delivered is from two-three weeks ago that I've already gotten. It seems that I've stopped receiving mail for account "redacted@frontier.com" after 10/8/26. Mail that's sent to other accounts seem to be delivered OK, but mail that's sent to this account doesn't show up. I've received at least some mail for account "redacted@frontier.com" for 10/9 and 10/10. Not sure if I'm getting everything. Mail seems to be received at the yahoo.com website for both email addresses [redacted@frontier.com and redacted@frontier.com]. At least I hope it is! Mail also seems to be received using the yahoo app for Android [phone] and yahoo app for iPad.

Kan ikke modtage og sende mails. Får følgende besked - Kunne ikke skrive mailen i mailmappen. Sørg for at du har skriverettigheder til filsystemet, og at du har nok diskplads til at kopiere mailmappen.

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 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?

Hi, my mozilla has just stopped dowloading messages to my laptop. Oddly, any messages sent seem to be received, and a test to my phone to myself verifies. Any suggestions please I would be most grateful for!
