After creating an email message, I click on attachment button to attach a file or pdf document to the message. The file explorer screen opens for a second then closes, giving me no opportunity to attach anything.

Hello - I'm trying to transition from Outlook desktop to Thunderbird in Widows 11, but the setup fails (just stops) when I try to import my Outlook pst data. Ive tried the Outlook scan and repair tool - no luck. My file is quite large - about 20GB. Is that the issue? Is there a workaround?

Thanks for any suggestions.

Hello, since friday, 6.2. thunderbird does not launch new (and also not completely all older) Emails anymore. So I can't see all my recieved and send E-Mails. In all my 3 Mail-Accounts froms different providers it does not work anymore, without changing anything from my side I know. But from my handy, where I use google-Mail, it works.

I already checked synchronization settings and repaired the E-Mail-folders.

So, are there any technical defects or problems with thunderbird, an update for instance that caused trouble for instance? And what can I do, to make it work again? Atherwise I would have to quit thunderbird and change my Host.

Looking forward to your response and already thanks for support, all the best, M.

Does TBird support plus addressing?

Scenario: I want to reply to email sent "To: markfilipak+joe@...". To do that successfully, in the "Write" dialog, I have to click on "From", scroll down to "Customize From Address...", click it, and add "+joe". (There is a menu alternative: "Options","Customize From Address...".)

If I forget to do that, then my reply does not have "+joe"; it goes out "From: markfilipak@...".

The Issue: When Joe replies to _that_ message, it does not have "+joe", so Joe's reply is trashed. (It's trashed because a filter I wrote automatically deletes messages that do not have "To: markfilipak+<something>@..." in the header.

The sensible way to handle plus addressing is for TBird to recognize plus addressing and to automatically make my "From" header from Joe's "To" header. That way, "+joe" will always be there.

Is there a way to do that?

Thanks Folks! -- Mark.

I had just started utilising Folders. Today I wanted to move an important email where I could easily find it again. I created a new folder, went to the inbox, clicked on the email in question and moved it to the new folder.

Then I went to the new folder to check that it was there safely and it was and I shut down my laptop.

Later I got home to start work. I looked for the file and the folder was empty. I ran the search that I had run previously and it now returned nothing found. The email had vanished.

I moved some rubbish emails to the same folder, none of them arrived there, all have disappeared and are not to be found in the deleted folders either.

Really annoying and frankly a deal breaker for using this software going forward without a satisfactory solution.

Hi!

I've added some subfolders to my inbox on my laptop but these folders dont appear or sync on my phone, I've checked all settings and they seem to be in order. Can you point me in the right direction to fix this?

Cheers,

Henk

My emails that are in Sent or All Mail are all out out order by date - random - different dates. I don't know what happened? I expect to see the most recent first - just as i do in my inbox. It is ok. They are fine in Gmail - where they come from. Thanks

I have used Thunderbird for a long time?

This has been happening for a long long time - probably a few years' worth of versions. I have just put up with it... currently running Tbird 147 and it just happened.

When editing an email (either the body or the Subject), if you use the backspace button (the one that deletes to the left) to delete some text sometimes the cursor will incorrectly be positioned about 5 or 6 characters further left than it should.

For example, if I had the text: "Quick brown fox jumps over the moon"

If I were to highlight "fox" in the above example, and hit backspace, I would expect the cursor to end up positioned between the remaining spaces after 'brown' ( pipe symbol here is meant to represent the cursor position): "brown | jumps"

But instead what happens is that the cursor ends up somewhere among/before the word "brown". It's always further left than it should be, by 5 or 6 characters.

I believe it only happens when highlighting multiple characters and then hitting backspace. It may be more (only?) prevalent when editing/replying to an existing email. (But I'm still only editing the new portions that I add at the top of the email; I'm almost never editing in amongst the original quoted email content.)

I also haven't ever been able to figure out how to make it happen, sorry. It is just random...It will happen once in an email, but then not again. But it happens frequently - 3-6 times a day perhaps. (Depends on how many emails I am editing.  :) )

I don't believe that I have noticed this issue if I were using the Delete button (deletes things to the right). I don't think it happens when backspacing one character at a time...but it might. I also use Option-Backspace to delete whole words at a time (instead of highlighting the word); not exactly sure if it happens only if highlighting a word, or only if Option-Backspace, or single key press... sorry, it is so random and unexpected that I don't have more specifics.

How to connect email account!? I have been tring for days to set up email account incoming server settins accept but outgoing page despite green ticks will not let me finish, I am 80 and do not understand why I am being blocked when allsettings have green ticks??

Tried to send a rather routine email on Outlook account. Wouldn't send. Checked settings. Outgoing server, which I set to smtp-mail.outlook.com, had "magically" changed to an outlook365 server. Switched it back. Still wouldn't send. After some investigation and some suggestions from copilot, I noticed my Surfshark VPN was on. I don't run it all the time, just when I need it to log onto blocked sites. Copilot said: Surfshark is notorious for silently blocking outbound SMTP ports — especially 587, 465, and 25. Switched outgoing port to 465 as suggested by Surfshark support and tried to send again, without Surfshark on. Still wouldn't send. Finally went to outlook.live.com to send the message. Went OK. Kinda baffled. Anyone help?

Hallo, ich habe meine E-Mail-Konten in Thunderbird umgestellt von POP zu IMAP. Meine Filter-Einstellungen waren bisher gültig für "Lokale Ordner" (die Filter musste ich manuell starten) Wie kann ich die Filter-Einstellungen auf den Posteingang meiner IMAP-Konten kopieren/migrieren? Danke, und Grüße aus Berlin

I've attached a screen shot of the main folders seen when I view these as 'Unified Folders' with folders names starting with *01, *02, *03 etc. Somehow, *04 is no longer appearing in this list and has instead appeared inside the *03 folder as seen in my second screen shot. I don't know how this folder and the many sub-folders it contains was moved into the *03 folder and no matter what I do, I can't move the *04 folder out of the *03 folder to sit where it should between folders *03 and *04. Can anyone point me in the right direction to move the *04 folder into the desired location? Thanks in advance, SteveJ
