Dear users,

I installed thunderbird on my pc only to open .mbox files containing archives from past years.

I read in the guide I need to add a plugin called ImportExport NG to open mbox files, but first I have to see the "local folders", which doesn't exist.

I attached the screenshot of thunderbird just installed on my pc and launched. I miss the "local folders".

How can I fix?

Thanks

I can get to the "stored passwords" box, but the email I need to change the password for isn't listed there. I have tried to send and receive messages but nothing makes a "enter your password" box pop up. All I get when it tries to retrieve messages from Gmail is a box to give my email, (just that, not a password) and then an error message that it won't work and there is no more information. I'm using Linux. I've had both this particular email address (as well as others) and Thunderbird for years, perhaps two decades, and I can't figure out what to do now. I was going to change all my email passwords for security reasons, but there's no way I can do that until I can get Thunderbird working with POP access again. Thank you.

I sent an email to myself and got: Sending of the message failed. An error occurred while sending mail. The mail server responded: RCPT TO:<[email removed]@bell.net> User unknown. Please check the message recipient "[email removed]@bell.net" and try again.

How can I fix this?

Hi,

I have just started using Thunderbird and I'm trying to change the default colour for a hyperlink.

I have tried about:config -> browser.anchor_color and browser.active_color but neither has worked.

I also tried using a user.js file but that didn't work either.

I would have thought this would be a fairly basic thing but it seems to be impossible.

On Windows 11 when I try to set up two accounts for two separate users on the same email server I get an error. When I do the same on Windows 10, it works as expected. Both Windows have the exact same versions of Thunderbird. Why should this be? Can I do something to get it to work? I will provide any additional information requested to get at this.

I am a long-time user of Thunderbird and have relied on the calendar application extensively. I recently had to purchase a new computer and had to install updated software for everything including Thunderbird. The calendar is giving me fits... When the computer is turned off, I lose all records of previous meetings as well as all scheduled meetings in the future (as well as any scheduled recurring meetings) along with the links to the online meetings. I assume that I have a problem in my settings but I don't know where to begin... I have looked for other similar problems on line and most seem to be associated with sync-ing with other calendar applications - but I don' use other calendar applications and don't sync with any other applications.

Any help would be greatly appreciated.

Tried all suggestions on re connecting thunderbird to gmail with no success. The new authorisation used by google is not working. I have thunderbird installed on Linux mint. Since i cannot use thunderbird i have moved to Evolution email client which has no problem at all connecting to gmail.

Please help me to get my old version back. This new version has among other things a huge long list of I guess emails with no content just numbers n, I want the old version back please this is too confusing and does not work for me. I was asked and said yes by mistake.

Please forgive a very basic question. I think I know the answer but would appreciate having the correct one from the pros.

My wife and I each have Thunderbird installed on our computers. While we each have individual email addresses, we also have one email address we share, and we access it via Thunderbird.

If I'm marking certain messages as junk on my computer, will that designation only apply to my computer or, because of the common email address, will it mark those same messages as junk on my wife's computer?

Thanks for any help with this.

I have a Google hosted domain email address. I've been using Thunderbird for a long time and I'm familiar with the problems of Gmail and Thunderbird not playing 100% nicely.

With that said, I have an 80+GB "Sent Mail" folder and I need to bring that back down to what the actual size is.

Any insight on the most efficient way of doing this?

My gmail account has two Sent folders.

1) A folder Sent in TB. Its location in properties is (host)@imap.gmail.com/Sent. But its contents correspond to the gmail account's label [imap]/Sent.

2) Another folder Sent Mail in TB. Its location in properties is (host)@imap.gmail.com/[Gmail]/Sent Mail. But its contents correspond to the gmail account's System label Sent.

So gmail's sent mail appears in #2 - TB's Sent Mail folder - and TB's filters that run after sending mail don't run on it.

How can I straighten this out? Just swap the locations in the two folders' properties? That will make them incorrect but maybe make it sync correctly.

I'm still running Windows 7 (it works for me) and Thunderbird (version 115.16.2 (32-bit)) has been my e-mail client application for many years.

Inside Thunderbird I have a series of sub-folders (which I shall refer to as 'folders') named & arranged by years & months.

Any received e-mails that are 'personal' (i.e. not news items, previously OK'd advertising, or junk) get filed into the current month's folder (which is 'inside' the current year's folder). (Towards the end of a current month I create the next month's folder.)

I used a wired USB mouse with two buttons ('left' & 'right').

When things are working like they are supposed to (and I have received a piece of personal e-mail that I want to store) I 'left click' on the e-mail (in the 'inbox') and (while holding the 'left button') 'move' the e-mail into the current month's folder.

(the 'problem') Once in awhile I accidentally click the 'right button' during the process of moving an e-mail from the 'inbox' to the current month's folder.

To-all-appearances the e-mail 'disappears' though a few times I have found it in an 'adjacent' month's folder (I also look in the 'trash' folder').

So far my only 'solution' (I at least have a copy of the message) is to go to my e-mail server (I have it configured so that it does not automatically delete messages) and 'forward' the message to myself (in which case I am shown as being the 'sender' when the message arrives in the Thunderbird 'inbox').

(my question) Does Thunderbird have an (undocumented ?) 'disintegrate' action ... where a message can be completely erased as a result of an accidental right mouse button click ... or is there some other folder where I should look (other than 'adjacent' month's folders and the 'trash' folder) ?

I converted to Thunderbird 128,11.1esr in May 2025. My address book did not migrate to the newer version and I don't have the old one. Also, I don't know how to return to the previous version of Thunderbird.

Hi, I am retired, but it does. not mean that tb shall be useless. Used to be simple and to make messaging easier. Now it is opposite.

When replying to a message, I want to change font of what my friend have sent me. Color picker does not work. I press the square, picker appears, I select the color, it appears on the picker, I click ok, and close. Nothing happens. Nothing happens, Nothing happens. I repeat, and it shows black as chosen color. I chose red. There is no way to select and use the color. Some time ago, someone wrote that it kind of works. Kind of works. When you choose color, you must not use it, but close the color chooser. So far, nothing works. It is handy to change the font color but it does not work. But if it works, who knows how to use it. NOt intuitively at present.

Also when the message arrives, I have no clue that it has. It does not indicate on icon anymore. But when I open the tb, i can see on one or another account so many messages new, unread, but am struggling every time to find them out. So far, I have to search every time again and again to filter only unread.... This makes tb very difficult to use rather than easy. Can't you make a simple version of tb without a million of useless to me features. I want to have an access as used to be to all email and in an instant to be able to see, not search the new ones? Is it impossible? Thanks. Michal
