Thunderbird Community Forum

When sending an email using the keyboard shortcut, the settings tell me that I can set TB to give me a confirmation prompt. Why can't I get a confirmation prompt when using the Send button? Is there any way to make TB do that?

I set TB to run a spell check before sending, and that gives me an opportunity to cancel the Send operation. But it only works if the email contains a misspelling.

Thank you.

My Thunderbird calendar refuses to display dates in European format, namely day-month-year. I have read lots of helpful hints on the forums and tried everything, but nothing changes. My system is Ubuntu 25.04 with Cinnamon 6.4.8. Thunderbird version is 140.3.0esr (64-bit). Some of the suggestions refer to settings that are no longer there compared to earlier versions. For example, Settings > General > Language and Fonts has no format options. I have also used the config editor while TB was not running and added ntl.date_time.pattern_override.date_short and ntl.date_time.pattern_override.time_short, without any effect. Dates in the calendar still always appear in the illogical American month-day-year format. This is confusing, to say the least ! Has a solution been found to EASILY select the locale and formats that should be used? At the moment, the settings are under different menus and in different locations, and TB seems to be making it as difficult as possible to get these set - permanently ! - to the user's preference.

Yesterday I upgraded my PC from Windows 10 to 11. Today I discovered my Local Folders are not visible. Searching tells me the messages still exist, but TB does not show the folders. I did the same upgrade a month ago on a laptop (Windows 10 Pro to 11), no problems. I didn't externally back up the messages as I am a dinosaur and don't know how, but at least they are still on the hard drive. Thousands of them though so I need the local folders back. Tried all the fixes I can find on the Community Forum, without success. Can anyone help please? Bob

I would like help removing one of the folders called drafts as it is empty and uses the other for subfolders. I have tried right clicking but it has no effect on removing it. Only the draft folder where the subfolders are located can be removed. How do I remove the extra draft folder. Thanks in advance for your help.

I use Thunderbird on Windows and on Mac. I'm wondering why the startup time on Mac is significantly longer on MacOS. I'm currently on Tahoe 26.0.1 but Thunderbird has always been a slow starter. Can I change any setting to remedy this. At the moment I have two mail accounts configured both Gmail.

I'm in the process of cleaning up Thunderbird e-mail before moving to a new computer. I started with 11,593 e-mails in my Inbox and 7,799 e-mails in my Sent folder. I'm now down to 7,634 in my Inbox and 4,965 in my Sent folder. I've allocated 2 weeks for this process and found that it's taking me about 3 hours per day to meet my daily goals. I'm finding that I'm spending at LEAST half the time responding to "Empty-Trash/Compact-folders" requests. There are times I can delete 50 e-mails at a time without getting a request. Other times I will try to delete ten e-mails and get the request. With the old version of Thunderbird I could literally delete hundreds of e-mails at a time. Can you help? Russ Bukwa Yardley, PA ps. I have intentionally given you specific numbers. Based on my software- and test-engineering experience, I speculate you need to create a stress test to solve this nagging problem.

My windows 10 PC died. I copied the the profiles folder from the old appdata/roaming/Thunderbird to the new Win11 PC, but TB does not pick it up, asking to create a new account "John Doe". Any ideas? Best, K.

Please tell me how to get that account working on my laptop, thanks!! It keeps asking for my password, but doesn't accept it. I know it's correct, because I verified it by going into Thunderbird settings. And as above, the account works fine on my desktop computer.

Tuesday Oct. 7, our ISP converted to a new e-mail program. I could NOT log in/on I called our ISP's help desk. The 'technician' could not help me log in to our Thunderbird POP 3 account. He had me, WITHOUT asking if I had essential - legal - medical-etc. e-mails in the IN BOX or in folders! He NEVER warned/cautioned all ?would? be lost - GONE.

I URGENTLY need to recover all TB POP3 IN BOX & e-mails in folders. I need to access legal messages today, if possible.

If Mozilla does not have a recovery program, what do I do? I am not seeking to recover ' deleted messages (unless his having me change from the POP3 account to a 'new' IMAP account is the same as ' "delete" '.

Any & all prompt responses APPRECIATED! Remain WELL & Be SAFE!

HI all. This is a good one. I recently got a MAC, my first one, so dont know much about it. I installed thunderbird and can receive via IMAP but cant send via SMTP. I have smtp setup EXACTLY how it is on my windows PC which works. When I hit send on a message, it immediately comes back with "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) <maileserver.com> timed out. Try again. This message comes back immediately, as in .000001 second. This particular mail server I own and is on my network, and checking the logs, the request never even gets to the server, so its not a server issue. (Again, it works for all my other devices and other clients). server info, password etc are correct. I tried deleting the account and recreating it but no go. From a command tool, I can telnet to my mail server on port 25 and it answers and I can interact. If I use the built in mac mail client, it works fine. So this is definitely a thunderbird issue from what I can tell. Thunderbird 143.0.1 (aarch64) on 26.0.1 (25A362) Any tips appreciated, Im ready to take a bath with a toaster. Thank you!

thunderbird won't start after installation giving message that a version is already running. I end the task in task manager and it doesn't help, then restart with same erro. I tried deleting the parent.lock file from the profile and that didn't help. What next? Has anyone solved this issue?

When trying to add my outlook.com email account to Thunderbird 143.0.1, using the instructions at https://support.mozilla.org/en-US/kb/thunderbird-and-exchange, I get an "Exchange auth error." I'm able to add the account manually using imap, but I want to use Exchange so I can access my outlook.com calendar and contact when TB is updated to include them.

For some reason (accidental key stroke?) one of my email account's folders are no longer arranged alphanumerically. How can I reset the order to alphanumerical? I can't find a menu item or setting to do this. Thanks

Hello, my email service has shut down for the second time. When asked to open, a small window appears and says the system is affected by a whatever. The window only lasts for a couple of seconds.

I tried to follow the instructions as how to get my profile, but is was lost due to an internet access cut.

Hoping someone can help. regards Stephen

Hello,

I've used Thunderbird on Linux for a while and love it! I use it for multiple email accounts from different providers.

Until recently I manually Archived email in to Local Folders on my PC. I do this to remove email from my mail providers and to avoid storage limits.

I recently learned that if I I set the "Message Archives" option to a specific folder for each account under "Local Folders" I can either manually archive there or I can use an Extension like "AutoarchiveReloaded" to do this semi-automatically. Great!

Unfortunately for my main mailbox only, despite being configured to write to a sub-folder under Local Folders, Thunderbird seems to ignore the settings. It always tries to create an Archive folder in the mailbox itself. Every attempt creates a mess which takes time to cleanup.

The mailbox in question:

• Uses IMAP
• Has "Keep message archives in:" set to "Other:" "Local Folders > Archives > (the name of the account)".

I am concerned that if I try "Keep message archives in:" "Archives" Folder on Local Folders it will combine with all my other archived accounts which are sorted in to sub-folders correctly.

Is anyone able to help please?

Thank you!

Greetings! I read everywhere that we must install the Lightning add-on to use the calendar feature in Thunderbird. But when I search for this add-on, I get a bazillion options, none of which appears Lightning. There is something called Lightning Calendar Tabs that keeps coming up. Is this it? Doesn't seem so.

Where can one download/install the Lightning add-on?

Thank you.

I am a M365 - leaver, and working several months now with Thunderbird/LibreOffice/Nextcloud. Sometimes I'm proud of what I learned and can do with the new software. Sometimes I'm a little lost in the woods.

I'm using the add-on Quicktext to insert default html text, like a template, in some of my my emails. One of the templates is a notification for my customers to inform them the invoice they received from me is not yet paid.

In the former software I was used to click in my template on a datepicker to insert the senddate of the invoice. I tried to insert a html-datepicker. This appears in the email, but is send to the reciever as a datepciker, not as the date I choose.

My question. Is there a way to insert a datepicker in a template like Quicktext, or is there a better add-on for this goal?

An old forum describes how to sync calendars in Thunderbird. Here is an easy solution - In the left-hand pane of your calendar page, right-click your calendar name/ export calendar - into a removable device. In your other computer - Tools/import/ import from a file/ choose to import calendar - easy!

I have used Thunderbird for years. I am on the esr update channel, 140.3.1 esr, and it says it is up to date. I just learned that there is another update channel, called "release". My Norton Internet Security program tells me that Thunderbird is out of date, and that the latest version is 143.0.1. Maybe it is confused because of the two update channels? Why are two different configurations maintained? Is there a reason that I should switch to the other one? Thanks in advance for any clarification.
