Thunderbird gemenskapsforum

Starting yesterday, Thunderbird will not let me delete all the junk from my Junk folder. When I right click on it and select Delete, T-bird freezes with NotResponding and I have to restart it. Once I went through and used Delete on the individual files within the Junk Folder. When I restarted T-bird, it had moved all those files to my Inbox - several thousand of them.

Can I simply delete the Junk file at \AppData\Roaming\Thunderbird\Profiles\hxza0a1k.default-release\Mail\mail.aircraftdesign.com? Or would that kill the whole thing?

Any other workaround? I spent 4 hours talking to Network Solutions, they checked all my account settings and said it is all correct.

thunderbird is not sending or receiving email to a particular legitimate email address; never had this problem in the past--it's just one particular email--please stop blocking it; @inreach. garmin.com

I like to sort my mail using the menu functions

Message-MoveTo-RecentDestinations

Unfortunately, for some time now, the "Recent Destinations" list remains very small and most folders, regardless of how recently I moved messages to them, do not show up on the list.

I have tried quitting TB, deleting folderCache.json, but that makes no difference. The list stays the same, and it does not get updated for most folders.

Maybe that approach is no longer a panacea :-) and there is some other way to fix this?

All emails in my trash folder disappeared. I do not know if this is due to something I did, or some other reason. Is there any way to restore the deleted emails?

When checking for new email a pop asking for the username and password of the for the email server. Also when a separate email client is downloaded. This only happens when. using a mac book pro. No problem when. using Ubuntu.

Hi. Since the Thunderbird update in March/2026, my Bell sympatico.ca email is no longer able to send emails out through Thunderbird. No error messages but emails never get to destination (I tried sending to myself on both gmail and sympatico accounts). I receive emails without issue. I tested the sympatico from the web or my iPhone and it works. Seems something changed in T-bird back in March?

I validated the Outgoing SMTP server settings and all seems OK (See attached file for screenshot of settings). Any idea why and what changed to cause this?

I've been trying to connect for over an hour and I always get the answer; " Connection to the server impossible. The configuration, username or password are probably incorrect. My access provider is “Orange” and I made the mistake of accepting “Unlimited Emails”, I have 650,000… I work on a MacBook Pro Apple M1 Pro 26.3.1 (a) and the Mail app is very saturated and Tchat Gpt advised me to use your “Thunderbird” app I changed my Orange access password about 4 hours ago. Please guide me towards making your application work properly.

When I try to install my account Office 365 for my association's account (XXXX@patapon95.fr) it doesn't word with Thunderbird (I can connect on Outlook on the same account). I can also connect with my personnal acount on xxxx@outlook.fr on Thunderbird.

突然、どこにもメールの送信ができなくなってしまいました。 受信はできます。 KDDIを使っていますが、問い合わせしましたが、サーバーに問題ありません。 Webメールでは送信できます。 Thunderbird側の問題のようです。 添付のようなメッセージが表示されエラーになってしまいます。 解決策を教えてください。

Suddenly, I can no longer send emails anywhere. I can still receive emails. I use KDDI, and I contacted them, but they said there are no issues with their servers. I can send emails using webmail. It seems to be an issue with Thunderbird. The message shown in the attachment appears, and I get an error. Please let me know how to fix this.

Changed p/w as solution no help Today for some reason Thunderbird won`t download from xfinity. Worked well yesterday,been on phone with xfinity about 1 hr. or so. restart pc no help

Hello,

In my Thunderbird Profiles folder, I can drill down to ImapMail. I see multiple subfolders prefixed with my imap server name. eg:

- imap.server-5.com 10.85GB - imap.server-3.com 8.83 GB

and so on. The datestamp on each is different.

Within the two examples above is a large Inbox folder taking up ~8.8GB.

The size doesn't concern me as much as the fact of having two of these. I'd like to understand what Thunderbird is doing under the hood here. Does it create new imap.server-#.com folders periodically as backup/recovery folders?

I'd like to recover space where possible but if these are protective measures, I could live with that. However, if it creates future folders and replicates 8+GB of data multiple times, I'd like to know what steps I can take to free up disk space.

Thanks,

I was just notified that my email provider is ending service after 30 years. I need to move all my folders and messages from my old Provalue account to a new Gmail account. Is there an easy way to do this? Can I just change the account name and password as well as the server settings? They are both Pop3 accounts. I also need to point 131 message filters to the new Gmail account. Is there a way to do this without having to rewrite all of the filters? Do I need to copy all of the folders and messages to the new account manually? I have 30 years of emails that I still refer back to occasionally. I need help, what do I do? Thanks in advance for any help I can get.

Mein Betriebsystem WIN 11 Free-E-Mail bei Telekom Eingegange E-Mails werden auf dem Server von T-Online nicht gespeichert und auf meinem Thunderbird nicht im Ordner Posteingang sondern im Papierkorb vom Lokalen Ordner nicht im Posteingangs. Auf dem Handy werden Sie angezeigt und können gelesen und Bearbeoitet werden. Beim nächsten öffnen der E-Mail App werdenSie gelöscht.

Welche mögliche Ursachen gibt es dafür.

My email is very slow since I moved it to my new Dell laptop, sending, reading new messages, deleting and moving, NOT old messages. It was also slow on my old tower PC, but not this slow. I might leave Thunderbird if this continues. Not worth my time. Thank you!
