I-Thunderbird Community Forum

Hi,

   I've used Thunderbird on Linux for about 20 years and it has worked flawlessly connecting to my ISP mail for both sending and receiving messages. About 2 weeks ago I tried to send a mail and got an internal error back from the ISP SMTP  server that the message was being blocked as possible spam. POP continued to work fine.

I tried renaming my local .thunderbird directory and downloading the latest version of Thunderbird to try a fresh install. It behaved exactly the same way.

   The frustrating thing is that KMail, an alternate Linux mailer works fine with the exact settings that fail on Thunderbird. I can also send mail from my phone when connected to the same ISP wifi as the Linux machine. 
   I am not sending out messages to large groups of recipients. It will fail (but work in Kmail   and K9Mail on Android) with a trivial test message to myself. 

Any ideas how I can troubleshoot this? I like Thunderbird but can't use it if I can never send mail.

Thanks!

I accidentally activated the OneDrive sync. After the mail directory were uploaded to the OneDrive cloud, thunderbird mail can only see each new mail title, but I cannot open these mails after I double click into them. It will just come back as directory and file not found. In other words, the paths are valid, but I can only see title without the preview nor the content of the emails.

File not found The file mailbox:///C:/Users/XXXXXX/MozillaMail/xxxxxx/Inbox?number=2704 cannot be found. Please check the location and try again.

Any help is welcome and appreciated, thank you in advance.

I was moving messages to folders from inbox and suddenly Thunderbird was only listing unread messages in all folders. I must have accidentally turned something off. Can you help me? This is rather urgent.

I have Thunderbird set up to download email from my ISP to an inbox under that account. A few days ago I saw that when I deleted a message it did not go the the Trash folder. When I look at the properties of that folder it shows a blank for location and while the message is deleted from the inbox it disappears. I do not know how that location was lost or how to restore it to it's previous value.

When opening a pdf file to print, the setting at the top defaults to "Automatic Zoom". Can this default setting be changed to actual size? Some pdf's won't print the whole page, leaving part of the right side off.

Hi,

I've been using Thunderbird for a while now, and while I generally like it, there is a huge problem: Sometimes, for no apparent reason, it doesn't retrieve any emails from either of the two accounts that I have connected to it. This happens maybe once a week or so, and it can take a few hours for me to notice, because it simply looks as if no new emails would be coming in - which is perfectly possible. But then someone tells me they sent me an email two hours ago, or I shut down the computer, and when I reboot it later, several emails I retrieved that should have been in my inbox much earlier. Once I notice the malfunction, closing Thunderbird and launching it again will fix the problem. But I'm a freelancer, I could miss important emails or job offers, so I need my email client to be reliable. Is this a known issue? Any idea what I could do?

I have Windows 10, by the way.

Thanks

thunderbird delete folders at will and randomly. folder remains at source but because thunderbird thinks it is still there it will not download folder again without making a change to folder name

Since the update of Thunderbird 128.1.0esr (64-bit) it freezes every couple minutes on a profile with 3 email accounts. One - no longer used - has about 2300 emails and is kept to access old emails.

The second is my primary Gmail account with 4351 emails in Inbox and 2234 in Outbox. Inbox shows 1.2 gb and Outbox 911 mb. The freezing has caused very significant challenges with reading and sending emails due to the freezing. As it is my primary email it is extremely concerning. And I am in the middle of a couple huge projects so I am getting a lot of emails.

The third is minimal with 26 emails.

I know it is not the number of accounts in the profile as I have 4 other profiles with more accounts and none of them freeze at all. (I manage/monitor other websites and keep them all separate.)

Also as others have noted the Filter function is doing weird stuff and rarely works properly anymore.

Hello!

I´m having some really weird issues opening mail with attachments. Sometimes they open normally and other times the mail body is just an endless stream of random characters and it slows down Thunderbird drastically.

These mails are in my local folder and saved from a Gmail account.

Hi, Why do I have to click twice in a row on a message in the trash that I want to delete? This is how I do it: The message is moved to the trash and should be deleted from there. I mark the message in the trash and then click once on Delete at the bottom right. A window appears asking if I really want to delete. I then click once on Delete and neither the window nor the message disappears. Only when I click on Delete a second time do the window and the message disappear from the trash. What could be the reason for this and how can I fix it? Thank you for a useful answer. I don't have much experience with IT and Thunderbird. Regards Manfred

I returned from holiday to find a new version of Thunderbird running on my PC. All the old email folders going back to 2017 and all my emails prior to 14 Aug. 2024 were gone! I don't have a back up of my hard drive. Is there any way to retrieve the folders and emails? Cheers Chris

We had 6 or 7 address books yesterday. Today we have two. We had at least 1,400 contacts. Now we have about four hundred...Business contacts, clients, HOA members. Auto fill of existing email addresses no longer happens, and especially this morning a new client's address was saved, we had been writing back and forth and all that info disappeared.

There were about 1200 emails in the main view yesterday. Today much smaller. I was told mozilla is quitting.

 Is mozilla disappearing and dead ?   We are very sad.  

We use mozilla to run this business. This hurts.

Thank you.
