since last update my *All Mail* folder is empty but at the top it says there are 138,944 messages. I can use some filters and SOME messages appear but by far not all that should match that filter. any clues? thanks,

Thunderbird 140.6.0esr (aarch64) on a Macintosh using Tahoe 26.1

I just bought a new computer. I would like to move my emails from my old computer to my new computer. I downloaded Thunderbird and I tried setting up my emails on my new computer, but it only took the emails that were in my in box on my 'server.' I also had subfolders in my inbox with emails in them, and none of the subfolders or emails in the subfolders moved over.

My email provider is Shaw, and my old computer I used the pop 3 format. On the new computer I'm using the IMAP format.

I have just watched the video on the support page - Move Thunderbird data to a new computer. I don't know if this is something I should do....is it my only choice....or is there something you can suggest.

Unable to download TB Setup 146.9.exe My fault, I aborted the download when it was taking so long. Too late realized that was normal. When I try again TB asks for second donation. What should I do?bold text

Hi All,

My name is Chris and I’ve been struggling for the past 3 days to add my Gmail account into Mozilla Thunderbird, and it’s become urgent. My computer often crashes and freezes, so I deleted my Gmail from an earlier version of Thunderbird and reinstalled the latest version.

When I try to add the account, Thunderbird just says “Looking up configuration of my Gmail” and never completes the setup. Oddly enough, I was able to add the same Gmail account into Outlook without any issues.

Is there something wrong with Thunderbird’s automatic server configuration for Gmail?

On top of that, I’d like to download all my past Gmail emails (sent items and inbox storage) into Thunderbird, but I don’t know the correct manual settings to use.

Any guidance on fixing the account setup and the proper manual IMAP/POP settings would be greatly appreciated.

Thanks in advance, Chris

Hi, my Thunderbird calendar reminders are coming up 4 hours after the meeting.

Running Kubuntu. System locale/timezone OK, TBird set to use system time (though manually making it the same didn't help). HW Clock matches system time. Pacific/Auckland.

Tried exporting all my appointments and re-importing them - no change.

When i receive email with linkages i am getting this reply when link is used

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

We apologize for the inconvenience.

TB Windows puts some messages in my spam folder even though I've put the addresses in my contacts and told it to check contacts before moving them to spam folder. It would be nice if the "Spam" button became a "not Spam" button.

when I exported my calendar on my old computer to an ICS file, it saved the original Disk and file path which is now different on my new computer. Some how the file path is embedded into the ICS file, why, anyway how to resolve?

I ran out of room on my C: drive a few years back, and moved user accounts to a new and larger drive G: and linked the USER directories to the G drive.

Thanks for looking

Kinda confused. Why, when I enter the unified folders, is the INBOX show empty when the ALL FOLDERS shows 6, indicating that, indeed, messages SHOULD be there? See attached.

I am so glad I make regular complete backups. Version 146 is a hot mess. Highlighted subject lines flashing, folders disappearing, On the second start of Thunderbird 146 I could no longer connect to hotmail, gmail, aol, juno, yahoo, All broke. Ended wiping 146 off the computer with REVO, deleting the profiles and reinstalling 145 and recovering the profiles and messages I used with 145 from backups made 2 days ago. Running the latest version of Windows 11. No need to reply, just a fair warning.

Hello everyone,

like the title says, I want to set appointments in the calendar to private. I have shared calendars. Therefore, I need to be able to set some invitations to private.

In Outlook, it's no problem to set an accepted appointment to private, but in Thunderbird, this option only seems to be available for appointments I have created myself.

Recently my Thunderbird mail has been 'glitchy'.

Sometimes I receive audible alerts for emails, other times I don't.

Sometimes the number of new emails received is correct, other times it shows 4 new emails when, across all my accounts, the number is 2 (for example).

Are either or both of these known issues?

I also noticed when I was watching a live music stream on TikTok last week, I 'had' no emails for almost 2 hours. As soon as I left TikTok and closed my browser window emails 'arrived', one timestamped 45 minutes earlier. The settings for that account are set to check for emails every 5 minutes.

Could the Chinese be 'watching me' 😁 or is there another more innocent explanation?

Been getting a bunch of this, usually in my TB TRASH folder, I think from the Outlook online server.

The server couldn't retrieve the following message:

Subject: "Stephen Tanner"

From: "Not available" ("Not available")

Sent date: 10/31/2024 2:25:02 PM

The message hasn't been deleted. You might be able to view it using either Outlook or Outlook Web App. You can also contact the sender to find out what the message says.

What does this mean? Outlook or Thunderbird? What do I need to do?

Hello, I just upgraded to a new mac and installed a fresh download of Thunderbird. Things are working well except for trouble subscribing to this astronomy calendar: https://cantonbecker.com/astronomy-calendar/astrocal.ics It works OK on my old mac/Thunderbird setup, but not on the new setup.

Details: New system, where the astrocal calendar doesn't work: MacBook Air M4 2025, running MacOS Tahoe 26.1, Thunderbird 146.0

Old system, where the astrocal calendar works: MacBook Air Intel i5 2017, running MacOS High Sierra 10.13.6, Thunderbird 115.10.1 (64 bit)

My steps to subscribe are Event and Tasks tab click Calendar On the bottom left I click New Calendar This opens a Create new Calendar window. Click On the network, Next I select "This location doesn't require credentials" and "Offline support" I fill in the URL: https://cantonbecker.com/astronomy-calendar/astrocal.ics, then click Find Calendars At this point on the new Thunderbird I get the error: Could not find calendars at this location. Please check your settings. (screenshot) But on the old Thunderbird I get that astrocal is available, and it actually works.

Any ideas? Is it a bug in the latest version of Thunderbird?

Thanks,

Peter H. PS: The new mac's default Calendar app subscribes to the astrocal calendar OK. It's just the new Thunderbird that has trouble. PPS: The new Thunderbird does successfully subscribe to another calendar, of Japanese holidays https://ics.calendarlabs.com/54/44bd6152/Japan_Holidays.ics That makes me more confused as to where the problem lies.

I've lost all the contents of a folder in one of my TB accounts, including all subfolders. Mysterious, and all the more so since another email folder which wasn't a subfolder of this one is now in there as a subfolder. Everything else in that folder has gone. Nothing has disappeared anywhere else. I've trashed and rebuilt global-messages-db.sqlite but this hasn't helped, no difference. Any suggestions? Thanks!

I have down loaded thunderbird and it appeares to work OK but when I need to print out some times the printers which are loaded onto my PC do not show in the drop down box there is only the option to save to PDF Is this because I have not yet paid any money ? this is because I would like to try it first Alan W
