To be clear, I seriously doubt the problems I am encountering are TB's fault! The problems may be my fault since I've grown older, I've tended (believed) using new versions of software present my mind a BIGGER challenge than using the older software/version I have been successfully using? I'm still using Version115.10.1

After our ISP chose to start using Zimbra Oct. 7, 2025 and their tech support could not assist me in getting TB working the had me remove POP3 settings for TB and change to IMAP with their software.

FINALLY someone helped me get TB working with IMAP. For 3 days grrr. Now the ISP says I need to use their web mail, Zimbra.

So might downloading the current TB version and somehow get the In box, all the folder contnets etc. over - into the new TB help?

I was going to backup everything tonight, now I have little to NO hope, without help!

THANKS & remain WELL plus be SAFE!

Hello, It is impossible to add the gmail.com email account. The SMTP service is not recognized by Thunderbird. This issue seems to have appeared after I changed the password of my Google account. Thank you for your help.

After updating my Thunderbird mail application from version 128 to 140, the shortcut icon for composing a message is no longer responsive and I cannot create a new message from it. I can no longer create a new message without right-clicking on a sent email and using “Edit as New Message (E)”. How can I get back to being able to create a message from the message creation shortcut?

Can the order of the sub folders in email account folders be re ordered. Is the add on "manually sort folders" still available? I there another method of doing this.

Hi, I want to print a list of selected events in the calendar, is that possible? Or, is there an extension that does it? And in the dream scenario I could export the selected lines to Excel.

I've tried this with both the Mac (Sonoma) version and the Windows (11) version. Thunderbird can't connect to the server. I've been setting up these accounts for years in Apple Mail, and I know the settings.

I was able to set up an account from a different email provider, however.

Two nights ago I uninstalled ExpressVPN from my system at the instruction of one of their "support" people. My computer immediately lost the ability to access half of the websites I tried to visit and Thunderbird wouldn't send or receive email. I rebooted and that fixed every issue, but since then, Thunderbird no longer checks for new messages for any of my accounts. If I manually instruct it to check, it downloads the messages with no problem. I don't use any add-ons, and I'm using the latest version on a Windows 11 PC. I have already tried deleting global-messages-db.sqlite, repairing each mail folder from within Thunderbird, clearing the cache, and running an install of the latest version. I have also tried changing the setting for each mail folder to alter the interval for message checks by a minute just to see if that would jog it, but no luck. I've looked at various other help threads for this and am out of ideas. Thanks in advance for any help.

How can I duplicate below in TB / BetterBird ?

We all know and see from left side of TB / BettreBird open app screen is the list of email accounts one has. In Outlook 2016 and onwards one can add just the Inbox of each mail account I have to a list called 'Favourites' and this resides above all the mail accounts and displays as a list of all the 'Inboxes' only. This means I just have to click on each respective inbox an it displays just that....all the mails in the Inbox. Currently I just have the list of account names where, when a mail is received and the corresponding circled number of mails shown I have to open the account to see the drop down then select the Inbox to get to the list of emails.

I am sure I am missing the solution.

Thanks for assistance.

Hello,

We ARE on version 145.

I spend an ENTIRE DAY following this information, especially that section regarding to "alternative method for manual transfer between Windows 10 and Windows 11 computers"

[https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-com...]

IT DOES NOT WORK! I may not be doing something (I could not find it), but in this consideration, I'm wondering WHY it's left there? Does it work for 144. Can I FIND 144?

Thanks, Lizzie's mum

An alternative method for manual transfer between Windows 10 and Windows 11 computers

This section assumes you have a default Windows installation and will work on computers upgraded to Windows 10 from previous Windows versions.

   Locate the master profile folder on the source computer as above.
   Locate the master profile folder on the destination computer as above.
   Note out of interest that your username (indicated by ~ below) on the two computers might be different due to legacy issues, but it will make no difference with a manual transfer as below.
   Close Thunderbird in both computers.
   On the source computer, copy the Thunderbird folders in both Windows(C:)/Users/~/AppData/Roaming and Windows(C:)/Users/~/AppData/Local to your transfer media, in separate folders so you do not overwrite them.
   On the destination computer, remove (or rename if you need a data backup or to preserve an old profile) any Thunderbird folders in the destination folders Windows(C:)/Users/~/AppData/Roaming and Windows(C:)/Users/~/AppData/Local directories.
   Copy from your transfer media the correct Thunderbird folders into the two folders above to replace the ones you have removed or renamed.
   Restart Thunderbird on the destination computer and test it, noting that your inbox tab should be identical to source, but that other tabs may have opened with Thunderbird messages.

I have Thunderbird 140.5.0 installed. It keeps moving my mail folders. I had them sorted in alphabetical order but a week ago it started moving my folders. For example, I have a folder named "FunWithTubes" but it keeps moving to the bottom of the list after "Y" and if I move it back then a day or so later it will be back somewhere else near the bottom. This is not the only folder it does this too but does not do it to all of them. How do I get it to put my folders back where I had them and leave them alone? This has got to be a bug.

Thank you.

I cannot send emails and always get the same error message, no matter what steps I have taken. This has been the situation for nearly 48 hours. During this time I have undertaken the following steps, as advised by Thunderbird (TB)/ Optus and Google (not in order).

Checked SMTP server settings (many times), Re-booted the Router, Uninstalled and reinstalled TB, Changed the number of Server Connections to Cache from 5, down to 1 (as suggested by the TB Notification), Tried sending a test message to my other email address on several occasions, but got the same error message. I have checked my Webmail account and can send and receive from and to my email accounts from within webmail.

As required in the TB help file, The following information is provided: SMTP settings (attached). Mail Provider is Optusnet. ISP is Firefox. Antivirus is Trend Micro Maximum Security Version 17.9. OS (details attached).

If I have neglected any required info please ask. Any assistance would be greatly appreciated.

Thank you. Flin

I have been using Thunderbird to access my comcast emails. I never had a problem with it. However, this afternoon, just out of the blue Thunderbird cannot download my emails, the following message popped up: "Login to server mail.comcast.net with username xxxxxxx failed." Then Thunderbird asks for a new password. When I enter the still correct password, it displays the same error message. I did not change anything in the settings before this error message popped up. I tried ChatGPT to get some answers, but whatever I changed it had no effect. I am attaching a screenshot of the server settings (I have of course removed my username). I would be grateful for any advice as to how to fix the issue. Thanking you.

Hello,

I had a TB crash, and clicked "OK" to submit the crash data before realizing all the "include data" options already checked.

How can I get Mozilla to remove this crash data from their site?

Thank you.

in all the years i've used thunderbird (am now on 64 bit version 144.0.1 on windows 11 25h2) the notification counter has never worked correctly

i can be sent an email & thunderbird notifies me there's 1 new email / unread message on the taskbar + tray icon

if i'm busy & ignore it / leave it thunderbird keeps on checking & incrementing that counter

when i actually download the new emails, there is still only 1 & not the number thunderbird has counted too

crazy!

Hello, When I first built this Linux Mint laptop I just grabbed the first Thunderbird install I saw, never realizing it would never update, now understaning how this works I want to install the flatpack version so I can be up to date. what is the best way to attack this, can I just install the flatpack and it will capture all my mailbox settings or do I need to start from scratch?

Thanks in advance Guy
