Since the update TB to v115.10.1 it will not connect to server, the server just times out.

BUT If I then login to the server directly from browser and check mail (IMAP by the way) using my web online interface I get emails THEN if I open TB it connects and downloads as it should.

This is weird. It's been checking more than a dozen email accounts for a number of years without errors.

Over the last few weeks, emails have vanished from my inbox, as well as trash, templates and other mail boxes. In may cases, no emails are being displayed, when "total message count" shows messages are present. In other cases, several days of recent messages have disappeared.

I have tried "repair folders," deleting "smart mailboxes' and even deleting the .mlf file of one inbox without success.

I have 6 email accounts including 2 GMail. The problem is in all of them. As the screenshot shows, there is a disparity between total messages and displayed messages in all boxes (partial view of accounts).

""

When TB starts up, the only folders I can see are Recent. I can go to View/Folders and click ALL, and as soon as I move the mouse away from that menu item, it switches back to Recent. This started on version 115.09, but persists after I've "upgraded" to 115.10.1.

It has now (5/3/24 17:25 CDT) been 2-1/2 days since I submitted this problem, and no one has responded that it has even been noticed, much less solved. One of my two email accounts is a POP3, and the other is IMAP. The IMAP account Inbox doesn't even show up on the TB home screen. (If that info is of any help).

PLEASE ADVISE. My emails are an integral part of my business, and I cannot get to almost any them.

Thanks, rehawkpe

I recently installed Thunderbird (115.10.1) onto my Mac (Sonoma 14.4).

After lots of manual housekeeping and deleting/filing hundreds of emails that had appeared in my inbox (that had previously been moved into other mailboxes or deleted) I have got my inbox down to a manageable size.

But now four of the emails in my Gmail webmail inbox are not showing in my Thunderbird inbox.

I have run a repair on the folder (Thunderbird inbox) but the discrepancy remains.

How can I make sure they synchronise correctly?

Also: I have 4 old drafts in my Gmail webmail drafts which are not showing in my Thunderbird drafts folder. I created a new draft email in Thunderbird and it is not showing up in my Gmail webmail. I have tried to point Thunderbird to my Gmail drafts folder in account settings selecting: copies and folders/drafts and templates/other/drafts on [myemailaddress] but it does not seem to make any difference.

Any help much appreciated.

My Thunderbird v. 115.10.1 (32-bit) Been using TB forever w/ GMail accounts Primary E-Mail is missing folders and has duplicate folders, one [Gmail] is inside the Inbox another is outside. Has [Sent] Doesn't appear to contain anything in either Junk and Trash folders. But, they do when I open GMail in my browser. My secondary E-Mail has no [Gmail] folder but does have Sent Mail, All Mail, Junk, Spam, Trash (empty), Trash and 3 that I created. This E-mail seems to function more completely. Is there a "repair install" a file to edit or something else to get me back to 100% operational? Can send folder properties if helpful. Image attached.

Comcast/Xfinity is binning email sent from Thunderbird to yahoo, gmail or hotmail

This problem started on April 24.

I have compared the Mozilla info at the front of emails sent to my wife before and after April 24. The only differences other than Subject and content are:

    From - Mon, 22 Apr 2024 16:34:28 GMT
    From - Sat, 27 Apr 2024 08:10:47 GMT

    Message-ID: <c43e9437-1603-41fe-bc73-699c2ac4ddb0@acm.org>

- The Message-IDs are identified as @acm.org - My sending address with Thunderbird is @acm.org - My ISP for Thunderbird is @comcast.net - If I send from xfinity.com which is comcast, the emails succeed - If I send from Thunderbird, the emails fail as follows

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 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.

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?

I know i have asked this already but i did not receive an answer of a solution and id really like someone to help me with this. It is a duplicate question but again no answer and id really like one . i want to remove it please do not tell me toget a new profile and lose everything i have. there has to be another way

Hello. I have an iCloud e-mail address registered in my Thunderbird mail manager and it was working fine since I initiated it with Thunderbird about 3 months ago. In setting it up, I had to log-in to my AppleID and ask for an "App-specific-password", which I did back when I set it up. Strangely, 2 days ago when I opened Thunderbird, I immediately received a small pop-up window asking that I sign-in to the imap server with the password. After trying to close this out several times, I decided to enter the app-specific-password that was provided back when I set it up. This did nothing and I continued to get the pop-up messages which inhibited me from accessing whatever iCloud e-mails I had received up to that point. I am able to cancel out the window message and if I immediately open one of my 4 other e-mail addresses also within Thunderbird, I can use them and with no issues receiving or sending. So last night, I signed into my AppleID again and asked for another app-specific-password and entered the new one into the pop-up message window related to the iCloud e-mail address on Thunderbird. This then held and I was able to receive whatever was scheduled to come in. But this morning, it is back asking for a password again and the one I received last night doesn't seem to work. Am I now going to need to obtain an app-specific-password for only the iCloud e-mail account everytime I want to access that address? And I have tried using the check-off box in the pop-up message window that provides for saving the password. It makes no difference. This is very frustrating, and I am now thinking that using this open-source manager requires advanced operational skills and time-consuming adjustments and baby-sitting of the software, which I do not have the patience for. Any guidance would be helpful and most appreciated. I moved over to this to get away from Outlook and the ever-changing updates which always seem to be driving at getting by your privacy to access web preferences and communication resources. It seems everytime Windows updates, I need to visit every privacy control and insure they are set where I want them. Thanks for any help!

when I select "get messages" from thunderbird, the system opens the email and reads and notes many messages then sends a message to me saying what it had done, one line per message. Then it does nothing. There is no listing lof messages sent. There is nothing.

If you have an idea about what to do, send it it cwskbenz@verizon.net. I will receive it on my cell phone which gets a copy of each message sent to my PC. regards, Bill Benz

Hi, Left post outlining TBird 115.x issues but I am the issue for the 'search' woes. The upper section simply needed to be shrunk - became a 2-headed arrow [when I figured it out.] Wonder whether other problems are also blatantly simply.

Windows 10. Thunderbird 115.8.0 While trying to figure out why my taskbar badge says I have 99+ unread emails (for the record, I only have 7), I hovered over the tray icon, and it says I have over 4 billion (with a B!) unread emails. That's not even possible with the email address I'm using it for. Why would this be like this, and how do I get it to be accurate?

I send .doc and .pdf files to my customers. When creating the outgoing email message and attach a file, I used to be able to see the file in the preview pane. I can no longer see the preview. Please help. This feature does work for jpg, tiff, and other image files.
