I just recently switched to Thunderbird and Libre Office to get rid of MS365. I am happy so far, if there wasn't one particular issue which I do not find a solution for:

I know how to sort messages with the newest on top, I know how to toggle the threaded view on and off. But I would like to use the threaded view and find it impossible to adjust a descending order within a thread. So I end up with the newest thread on top, but the thread headline shows the oldest message and if I unfold the thread it's in ascending order.

This is a major issue for me. To avoid overlooking incoming mails, I need to switch of the threaded view. Websearch didn't provide me a solution.

I have a saved search for unread emails and for flagged emails.

I move incoming emails to sub folders and as I occasionally update the list of sub folders this means that I need to then update the properties of these saved searches to add the new folders into the folders to search list.

Recently I have noticed that when I try to edit the folders to search list it no longer shows the folder list - only the parent email address. (the existing number of chosen folders is still given - so the search still does work for the previous folder list its just that it cant be updated)

This issue occurs with all existing saved searches and also occurs if I try to create a new saved search

Any Ideas how this can be resolved ?

When I use Shift-ArrowKeys (or Shift-MouseClicks) to select multiple messages, as soon as I select the second message in the group, the Preview Pane switches from message preview mode, to some kind of an "aggregate text-only few-lines-of-peek" mode (don't know how better to describe it).

In this mode, it shows a few text-only lines of each message in the selection, which is usually of no value whatsoever because most eMails are HTM and the text shown is meaningless. I can't see the whole eMail as I select them in a group (usually to delete the group).

(I've attached a screen shot to show what I mean)

I want Thunderbird to stop doing that, and just show me a true preview of each message as I select it for addition to the selection group, so that I can read it and be sure I want it in the group, just like it does when I select a single message instead of multiple ones.

Can I get Thunderbird to show me the correct and full preview somehow?

Some of my older emails, which were in HTML, now appear as text with full headers and formatting data, making them unreadable. How do I convert them back to HTML?

Thunderbird 128.2.0esr (32-bit)

Hi, I have a problem, when i set outomatic reply on my account email has send, but with wrong encoding. I 'm writting mail in czech language, so you probably wont be understanding. In the picture is a screen of mail, that was automatic sent, please help me, what i should to change in settings.

The global search in TB is completely defective. I am now running 128.2.0esr and hoped that update might fix it. It hasn't. I just wonder, are there any older or non ESR versions I can downgrade/move to, where the search is fully functional?

I've read a number of posts regarding using Mail Store Home to enable the transfer of mail from a PST file to TB. I was under the impression that the archive within MSH could be run against a stand-alone PST file (that is, Outlook is not installed). When I select Archive Email as per instructions on other posts, and specify the location of the PST file and then run, I get an error: "This feature requires Microsoft Outlook XP/2003 or higher". Does it require Outlook to be installed, or am I doing something wrong? Also I am a bit unclear of the run sequence with MSH - do I run Archive Email followed by Export Email and what is the connection between the two? Refer to image attached. Thanks.

Why is my program stuck on "send later"? I see no way to change it to "send". How do I get thunderbird to send a message, not "send later" with no indication of how or when to send it?

Hi,

noticed some problems with the use of "Customize From Address" when sending out emails:

My configuration does have several free-mailers like GMX and multiple self-owned+self-run domains as well. Each mail account is configured to use their own credentials for Outgoing Server (SMTP). No sharing of SMTP credentials between accounts.

I have used the "Customize From Address" w/o creating an identity with my own domains a few times (the one-off use case, as described by TB). It is working with TB in general for each of my domains.

Now on 2 occasions I realized that sending via "Customize From Address" from customaddress@mydomain1.com ended up being sent to Outgoing SMTP-Server of @mydomain2.com. Therefor failing on submission.

Will try to enable some sort of logging in TB to find out why that is happening - not sure if that will provide enough detail to find out why this is happening.

Are there any recommendations you have or good resources on how the emailaddress of "Customize From Address" is matched with the correct Outgoing SMTP Server?

Thanks starfish

When I open Thunderbird it opens multiple tabs while attempting to get emails from an email folders. It doesn't allow to access any other email folders while trying to get messages from that particular folder and it eventually crushes.

Using TB 115.15. When I move a large number of messages (200 or so) to a sub folder the move goes fast until it gets toward the end, then it locks up until it finishes a few minutes later. When I tried to move over one thousand messages at one time, I let it run overnight, some messages moved, some only moved a date header of some earlier time (all the same time) and all messages were left intact in the original directory. After moving the messages a few at a time, I had to manually delete the duplicate messages in the sub folder. What is the maximum number of messages Thunderbird will move at one time.

Using TB 115.15. When I delete a number of messages, then empty the trash, I cannot delete another message until I restart Thunderbird. Is there a limit as to the number of emails I can trash prior to emptying the trash?

so today i was going through email deleting junk. i would search by keyword then highlight and delete. i had gotten a lot done when i noticed that if i went to read an old email i would click on the email and the page was just white. nothing there. i shut down the app and restarted it and the same. restarted the desktop and the same. i was looking around to find a fix and now almost a year of email is gone. all email from 10-7-23 till now are gone. i have received new email and all works fine. but a lot are gone. any ideas? thanx

I use Thunderbird 128.2.0esr (64-bit) to read mail from the Outlook server; these are the folder mappings:

imap://<email>@outlook.office365.com/INBOX imap://<email>@outlook.office365.com/Sent imap://<email>@outlook.office365.com/Drafts imap://<email>@outlook.office365.com/Trash

I used to also be able to read the Junk Email folder from the Ourlook server the same way, but the folder disappeared from my Thunderbird a couple of months ago. I tried re-adding it as a sub-folder, which is how I created it in the first place, but it won't appear on the list.

I'm not sure what else to do here. I don't know where the Thunderbird directories are stored locally any more, I'm using Ubintu 24.04.

Dear Sir or Madam,

I'm using Thunderbird already for a long time and I'm very happy about it. Until now!

Since 1-2 weeks the programme does not download my emails anymore. I have to go to my hosting company and download my emails from my various domains, which is a pain. I read your "solution" in the help section, but it does not help as yet. I don't know what I might have done to change the settings, but when clicking on "Get Messages" no text at the bottom bar apears that it is looking for mail, but only a blue coloured bar at the right bottom on my screen apears and when completed disappears again. When I then go to my host company (Dot5Hosting) I can find my new emails.

What do I need to do to solve this problem? Thank you very much in advance for your solution(s). Kind regards, Ronald Verwer.

I just sent a message in community forum (I think it was) about how some of my messages were loaded as raw html code, tonight. Well, I just found an interesting temporary fix: I send the offending message to "junk", then say it isn't junk, and send it back to my inbox: then it displays as it should. I tried to edit my original message here on Thunderbird with this new "fix", but was unable to. And it still doesn't solve why messages in my inbox load this way to begin with; but I thought it was interesting as a diagnostic feature.

I am still wondering whether to reinstall Thunderbird...

This has nothing to do with virus scans, because I don't have any going 24/7, that I'm aware of. Maybe Windows, though-- I'm never quite sure what it is doing. But no other 3rd party virus scans. Thanks.

Some of my emails tonight are displaying as raw html code. That is, I just get code-- no message. Really annoying! I saw another comment on here that suggested one needed to repair folder; it seems to me I'm always repairing my inbox (because I thought perhaps I wasn't receiving all my messages, but the problem may have been from the sender). I don't have any paid virus scan regularly scanning my PC-- except maybe Windows Defender, or whatever it's called these days? I am using Win 11. But I don't think I have any viruses, either. I often run Win Defender or free Malwarebytes-- but not whilst receiving email. I have never had a virus that I'm aware of. The problem just started. Should I re-install Thunderbird? Thx,

I have a client that has three laptops running Windows 11 and the latest build of Thunderbird. She has the same three email addresses (MSN.com, outlook.com and gmail.com) added to TB on all three computers. When sending a test message to one of the email addresses they arrive in the inbox on just two of the computers and not on the third one. All three email accounts have identical POP/SMTP settings and "Leave mail on server" is checked. Any ideas as to why just one of the computers would not receive inbound email messages? When I added the account to the computer in question, there were no error messages, and the account addition was successful. Any thoughts as to what might cause this?

I have a folder that indicates there are 13 messages in the folder, but only displays 4 of them. How can I recover the other 9 e-mails in the folder to be able to view them?

My message filters do not run. They appear to be properly set up. They don't work, even when I select "Run Filters on Folder", under the Tools Menu.

Here are my Filter Rules for one of them:

• Apply filter when: Manually Run (checked) Getting New Mail: Filter before Junk Classification (also checked)
• Match "Any of the following"
• From Is (sender's email address)
• Perform these actions: Move Message To (Junk on my email address)

I am using Thunderbird version 128.1esr (64 bit), Thunderbird Windows MSIX package, Thunderbird-MSIX-10 My system is Windows 11 Home version 23H2

Thank you!
