Thunderbird Support Forum

Been using Thunderbird for 5 or 6 years now and am a big fan. However, in the last few versions, the tool seems to be more and more resistant to actually checking for mail when told to do so.

It frequently does not check at startup ("Check for new messages at startup" is checked for all accounts), and also does not check when "Get all new messages" is selected.

I have tested this with known mail waiting to be retrieved and Thunderbird does not do it when directed. It did eventually do it, and downloaded the mail, but I am not sure why the reluctance to check on demand by the user.

It is possible it may just not be REPORTING that it is checking, but failing to get mail I know was there kind of makes that less likely.

The earlier versions, from 5 years ago, worked very well in this regard... always checked on startup and when told to, always reported the activity in real time as the check proceeded. The newer versions are not good at this. Or it is user error, which is definitely possible, but I'm not sure what I might be doing wrong.

Currently using Thunderbird V115.10.1 64 bit, running on Linux Mint MATE. This is the newest version available as of Apr 29, 2024, and the problem seems to be worse in this one than in the previous version. Not positive on that, but I did have a dickens of a time getting mail downloaded that I knew was there.

Any input or ideas will be most appreciated, thank you in advance.

Can't print emails or any saved Thunderbird files. I click on FILE>PRINT and get the print preview, butwhen I click on "PRINT" I get a "printer offline message". I can print from Microsoft Word or PDF files and any other program. It appears that everything worked well until the latest Windows update was installed.

I am using an HP printer and print via HP's Smart Print software which I believe is the default. I'm not sure if this is a Thunderbird issue or another screw up by Microsoft.

Thanks for your assistance.

I made no changes to anything, but a week ago, my thunderbird app on my computer stopped loading new messages and began to throw this alert when I try to save drafts or send messages: > Your draft message was not copied to your drafts folder (Drafts) due to network or file access errors. You can retry or save the draft locally. The email on my phone, through the mail app on iphone, still works perfectly. Both the thurnderbird and mail app are set up through IMAP.

On my Win 7 box, Thunderbird seems to be having access issues with my profiles. It can only find my profiles when running in administrator mode. I've tried resetting security info on several files, but have not found the right one. How can I find the culprit?

I am the beneficiary (or victim, depending on how you view it) of Cox Communications turning all email services over to Yahoo. Both Cox & Yahoo store messages on an IMAP server.

As seems to be Yahoo's custom, they provided minimal documentation. Last night, in a 3+ hr call to tech support, for example, I noticed that my inbox had exactly 10,000 messages. (I know. It's not Inbox Zero -- I'm a bad, bad boy.) This seems suspicious, so I asked Yahoo's tech support agent about it. At first they said Yahoo puts no limits on messages and blamed Thunderbird for this. Then I showed them my employer's Gmail inbox with 35K messages and said this proves it's not Thunderbird. Then the agent said Yahoo has no limit. Then, apparently after getting feedback from their "support team," they said there's a limit of 10,000 messages per folder. So, even Yahoo's tech "support" seems almost clueless about such undocumented "features."

I know I need to trim the inbox, but I also need to keep lots of messages currently in it. So, the first thing I have to do is to move a large number of messages from the Inbox to another folder whose contents will be fixed.

To do this, I first created a folder to keep the original messages, "Cox Inbox."

Then I created a message filter with the following logic:

• Match all of the following: Date, is before, 4/7/24 (the day before Cox migrated my account)
• Move message to, Cox Inbox

But despite trying this repeatedly (I also tried "Match any of the following"), most messages stay in the Inbox and relatively few make it to the "Cox Inbox." I don't know how to troubleshoot this. Can you help?

Not being able to get the filter to work, I tried brute force. In my Inbox, I highlighted all the messages I wanted to move, pressed CMD-C (I'm using a Mac), went to the Cox Inbox, and pressed CMD-V. But it seemed nothing happened. Again, I'm at a loss as to how to troubleshoot this. Please help.

Since this morning 99% of my tasks disappeared. When trying to reset the lost tasks I remember by converting emails to task or by entering them as new tasks from the taskbar, they do not save and do not show up.

I restarted thunderbird a few times. Whilst doing that there was an update. I think windows. Thunderbird tasks still not working. Checked updates and Thunderbird is up to date.

Converting emails to tasks is extremely important to me.

Hello everyone, I've been using Thunderbird with the Plugin FiltaQuilla as a tool to print attachments of incoming mails (this are alarm information for a fire brigade). Our dispatch center sends the mails out using PGP for encryption, the decryption works properly. Since FiltaQuilla cannot work on encrypted mails, I forward incoming mails to the same account which removes the encryption. The strange situation is: if the filter is executed automatically upon arrival of a new mail, it forwards the message, but does not attach the attachment. If I run the filter manually, it does as it is intended to. See the screenshot for details: the mail comes in at 5:53, the automatic forwarding arrives at 5:59 but without an attachment. My manual filter-test runs properly and includes the attachment at 8:22. I've updated Thunderbird only yesterday evening to V 115.10.1. Before the mayor update to 115, I had the feeling that this problem did not occur. Please let me know if and how I can provide more details such as logs. Best regards Andreas Schultz

Was trying to find a solution to new emails not showing but unread number increasing but no applicable articles were coming up. But after hours of trying solutions, I think the answer was to mark some older emails that were marked unread as read. Then the latest couple of days of emails started coming through. This happened when migrating Cox.net emails to Yahoo and then modifying Thunderbird account settings to retrieve them. This email account has over 14K emails from 2014 and later showing in Yahoo Inbox and somehow the Thunderbird Inbox is showing 26K, probably some duplicates, although I have been using the extension "Remove Duplicate Messages". In Yahoo, I made more folders for several older years and moved emails from the Yahoo main Inbox to those various years to cut the size of the Inbox. Any other suggestions would be great for similar situations.

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

I just upgraded to version 115.10.1 and I have since had numerous incidents where I could not move the cursor to add the next line etc. If I recall correctly this mostly happens after pasting text from a another email or other source. In fact there have been times when the entire composition becomes frozen. In this case it doesn't matter where you place your cursor, you will not be able to edit anything. Very serious problem and a major disappointment. I am always afraid to update at this point, and this is not right. The new releases need to be tried and tested.

Hi, like other users on this help service, I recently lost the ability to send smtp gmails on one specific gmail account, but receiving emails was OK. Every attempt to send brought a "send failed - enter new password" dialog box. I looked at a great number of "solutions" before I found one which almost worked, but I have modified/clarified it and post it here for others to try. First off, look at passwords in Settings, and check that you have an 0Auth2 password - very long and not anything you chose. Then go to Server settings, scroll down the left hand pane past all the accounts listed until you find "Outgoing Server (SMTP) and click on it. This lists your outgoing SMTP accounts. Highlight the one for the account which is not sending and click on "Edit" Change the authentication method to 0Auth2. OK your way back. Now go back to your displayed passwords and copy the 0Auth2 password from the incoming password box and paste it in the SMTP password box for the problem account. Now close TB and restart. When I did all this, it began to send emails again. Hope it helps someone else.

I am running Thunderbird on Linux Fedora. I have two accounts set up. One of them is an icloud account. Every day, many times per day, it prompts for password. I have a nightmare to get one for it due to the new way Apple deals with stuff like this. I have to get an 'App Specific Password', which involves logging in, which I hate doing and doesn't work because I use a VPN and Apple discriminates against VPN users and locks my account every time i login (even though it's the same IP address every time).

I did manage to generate one, which got rid of the problem for a day or two, then it came back, generated again, and so I go around, each time having to unlock icloud account, remove old password, generate a new one, paste it into TB and then its fine for a few hours/days.

Would be very grateful for any ideas why this is happening and how to cure it.

thanks

Thunderbird will not start. Message Can't Load XPCOM. Windows 10. Have uninstalled and reinstalled Thunderbird multiple times. No change. Have deleted the Thunderbird folder in Program Files and reinstalled Thunderbird. No change.

I cannot dismiss calendar invites sent to me from others on the Ubuntu platform. I can dismiss invites that I have initiated. FYI this doesn't seem to be the case on the windows release - I can dismiss "foreign" invites.

The only way to dismiss these invites is to delete them from my calendar (which I prefer not to do). Thanks.

In the attached screen shot they are two type of folders - One is yellow and looks like a paper folder and the others are rectangular in shape in different colors (here in res and purple) . I am unable to delete the rectangular folder that appear permanent and I don't even know how it was created as I used the same command "new folder" under the inbox or "new subfolder" under a yellow folder - I hope that this is clear : I want to delete the rectangular folders when needed

Whenever I open TB (115.10.1) new messages download. The problem is the newest message topic is in the Inbox list but it is hidden behind the column headings. I have to scroll the list down one message to see the newest message. Why is this?

Thunderbird fails to access comcast.net email accounts after years of working correctly. Version 115.10.1. I have tried changing the password many times after talking to Comcast support. The best they can do is suggest I contact you.
