I am currently using Thunderbird 115.3.1 (64-bit). The about info shows that I can update to 115.10.1, however, I believe there are much later versions but I don't know if I can update to the latest. My MacOS is 10.15.7 and that is the latest I can install.

I have a large amount of email stored on my MAC and not in the cloud.

I want to be able to access these emails that are on my hard drive, in addition to Thunderbird, in Apple Mail.

I have researched and it appears that the best way is to export from Thunderbird is into the mbox format. However, there does not seem to be a way to do this in the version of Thunderbird I am using.

How do I move all of my local email in Thunderbird to my Apple Mail?

Thanks for any help, Richard

We followed the instructions Encrypt emails with Thunderbird and GPG | Bacardi55's Web Cave and GPG Keys Management :: Fedora Docs which as I said results in my other system working as intended.

Could the non-working system be missing a package or a pointer set incorrectly? GPG and GPGME are installed. Keys are configured.

Sometimes, when I delete one email from the inbox, the inbox shows "no message found", even though there are still other emails in the inbox. The remaining emails are still in the inbox, they just don't show. If I right click on inbox in the left panel, and select "open in new tab", the remaining emails show in the new tab, just not in the main inbox. If I close out thunderbird and start it again, the emails show in the main inbox. The problem occurs occasionally, whether I select delete from the menu bar, hit the delete key, or right click on the entry and select the trash can icon.

This problem started maybe 10 or more updates ago. For each new update I think "surely it will be fixed this time".

I have included a partial screenshot of what it looks like after the problem occurs.

This problem is different than any other questions I have found in the search. It purely a visual presentation error, not disastrous, just highly annoying. Any solutions will be greatly appreciated.

I have some address books with a lot of names. I used to be able to open the Contact sidebar, then click within an address book, type a letter, and it would take me to the first entry in the address book beginning with that name. For example, if clicked within the address book list of names, and typed "B" it would take me to "Baker" if Baker was the first name in the address book beginning with a "B" It will no longer do that. Now, I have to scroll through all of the "A" names until I get to the "B" names. How can I enable that again? I'm using Windows 11. This has worked the same way for years and years and now has stopped. Help!

I usually run Thunderbird in a sized window to manage my screen real estate, using the classic layout and showing four messages in the folder pane. The problem is that when I maximize the Thunderbird window, the message pane stays at the height I set for the smaller size window. Is there a way to make the size of the message pane be a percentage of the available space, or at least lock the height of the message pane to the height I set for the folder pane?

Thunderbird Android v8.2 / Pixel 6a / Android 15 (Feb 2025 security update)

IMAP Push in use for Inboxes only on 3 mail accounts (2 Comcast; 1 Gmail)

  - Enable Push: "on"
  - Enable sync: "off" (for Inboxes; on for all other mail folders)


Installed TB in November 2024 and experienced no problems until recently. Beginning in early February 2025, inbox push/update stops working every ~24 hours. If I go to Android settings and force stop TB, clear cache, then restart TB, Inboxes immediately sync with servers and again function fine for approximately 24 hours (not exactly).

Using TB for 3 e-mail accounts. Only the 3 Inboxes have push enabled (and sync disabled). All other mail folders on each account set to sync every 60 minutes. This configuration was set up on initial installation and worked without issue until recently. The only system modification made in this timeframe was installing the February 2025 Android security update.

Anyone else experiencing similar issues? Any suggestions?

Thank you.

Re: Thunderbird 128.7.0esr (64-bit) under Windows 10

Unread incoming messages are indicated by a little red dot within the Thunderbird logo icon in the Windows notification area. When operating with a Unified Inbox, opening those messages in the Unified folder does not always clear the red dot, nor does the unread message counter in the left pane always decrement properly. What it seems to take to reset things when this happens is to expand the Inbox tree and simply click on the account name associated with the unread message. Anyone else see this?

In my TB128.7.0esr I have a Profile with several IMAP-accounts all residing on the same IMAP-server.

For ONE of the accounts, when I do a move (drag-and-drop) of an eMail from A to B (ex: from Inbox to Folder or from folder to Inbox or .....) - in Thunderbird the eMail becomes available in the target, and is removed from the source - on the Server directories the eMail stays in the source and is as well in the target and this until I do a compact or until I close Thunderbird

For OTHER accounts everything happens immediately !

I couldn't find any setting that might imply this kind of behaviour

And yes, I checked, the icon during the drag-and-drop, it doesn't have the +sign on it, so it's NOT a copy

Any ideas what might be going on ?

Hi,

I've searched this problem a number of times and not come up with a solution. I've been a Thunderbird user for decades and this is a new problem to me.

I have 3 email accounts in Thunderbird. One of the three is very old and has dozens of subfolders with old message storage. The other two have one or two subfolders at the most. All 3 accounts seem to have this same problem.

Ninety % of the time all messages download and appear in their inboxes just fine. But sometimes I'll get downloading X-number of messages in the bottom left corner of Thunderbird but nothing shows up in any of the inboxes. I check all TRASH and JUNK folders and they are all empty (I used EMPTY TRASH ON EXIT as a setting in all accounts to empty the TRASH folder).

If I go to the online servers for these three accounts no messages show up there that haven't already been downloaded to my inbox and seen by me. So it would appear there actually were no new messages to download even though Thunderbird indicated there were.

A few weeks ago I searched out and found instructions for using the REPAIR FOLDER feature and ran that on the inboxes. On one account 3 old messages I don't think I'd seen did indeed appear. But use of the REPAIR FOLDER feature since then has had no effect at all.

I use JUNK settings but rarely see anything show up in my JUNK boxes. Perhaps that's a clue?

Can anyone enlighten me on what is happening?

Thanks, BH

Good afternoon.

There is an IMAP mailbox with a huge array of emails and folders, and a large number of configured filters. The emails that were sent did not open correctly, i.e. we see one header, but a completely different email opens, this is not the case with all emails, selectively. This also happens sometimes in previously received emails, and it also happens that the counter for new unread emails in some folders does not display until you enter this folder. The problem is only when working through the Thunderbird client, it has been going on for more than a year, the client has also been updated many times. This problem is reproduced on other PCs when we are log in this user account . There are no similar problems in the browser. Please help.

I have been moving old emails into my local folders which are on an external hard drive.

I have successfully moved a few hundred emails but now get the following message when I try to copy or move any more emails to the local folders:

"The messages could not be moved or copied to folder 'discogs on Local Folders' because writing to folder failed. To gain disk space, from the File menu, first choose Empty Deleted, and then choose Compact Folders, and then try again."

I have plenty of space left on my external hard drive (650 GB, drive is only 25% used).

I have tried emptying all deleted folders (both from the account I am trying to move the emails from, and the local folders drive), and compacting folders, no effect.

I am wondering if there is some kind of maimum size limit on the local folders directory, either in Thunderbird or on my hard drive, that I need to reset ?

I am running Thunderbird 115.10.1 (64 bit) on Windows 7.

Any help appreciated.

"Nothing happens here" after the Microsoft OS install Thunderbird stopped working. I had no menu bar but it did download messages. I reinstalled Thunderbird and it installed Outlook then Thunderbird. I have a menu bar but none of the tasks is accessible. It downloads messages but I cannot open, delete or move them. I need to go to task manger to close the app. When I go there, there are multiple tasks for Thunderbird. Tried a shift start but I could not even see the inbox after deselecting addons. Just the menu bar and the rest is a blank page.

Tried a screen shot but this does not work.
