I have tried all the resetting of passwords and each item in the account settings ( I think I have). Each time when I test it says that the incoming server was found. Nothing about the outgoing server. I'm using Windows 11 and I think the latest Thunderbird version. I really need help to get past this. Further, when I attempt to send with "Control - Enter " keys, The error message uses the wrong server name.

where log in : Alert from account invalid parametr id

and when I try to send an email I get this error :

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

But I have everything set up correctly. moreover I have already successfully sent emails and received them a few weeks ago and I haven't changed the settings since then. And now for some reason it's not working

OSX Ventura 13.1, 102.9.0 (64-bit), Gmail imap, when Tbird applies filter to move message a strikethrough copy remains in inbox. A non strikethrough copy is in allmail. When I try to delete the ST copy in inbox it just removes the ST and the message remains. The left click menu delete works. None of these actions have any effect on the moved message. Messages are moved to Local Folders. When I select an unread message in the inbox it immediately changes to ST status. No messages have ST in Allmail. I tried to set the delete action to move messages to a "New trash" folder and most of the inbox vanished. The "Inbox" appears to be worthless and undependable. All I am trying to do is to have my filters work like they used to when I was using POP3. My wife's windoze machine is now having similar issues.

In version 102.10.1 I can change the font size of the various Thunderbird panes independently. I've used the layout.css.devPixelsPerPx variable in the Config Editor to get the menu, folder index, headings, and other fixed parts of the UI to a reasonable size, but the message pane, reply quote, and other parts of the displayed text are way too large. I've tried to use the font size controls in Settings to adjust them, but with little luck.

So, what I would like to see is a concise table showing each font size parameter and exactly which panes and text it applies to. Or, I would like to see written instructions for making the font size the same for all text appearing in Thunderbird, anywhere in Thunderbird.

Or any other answer that is equivalent to these to help me achieve the same font size throughout Thunderbird.

Note: while I can see that some text is too large, I have not verified that a recipient would see text that is too large, since I'm not certain how to test for this, or how to text for both plain text and formatted text. I prefer to send plain text and receive formatted text, if that is relevant.

After changing my password I get the following error message: "Server imap.pt.lu has disconnected. The server may have gone down or there may be a network problem" Thunderbird is running well on my mobile, so why not on my PC? I have tried these things: Internet connection is working (as you can see from this mail) I have checked server settings, they seem okay. I have deinstalled and reinstalled Thunderbird. All to no avail. Can you help me?

Good morning

My client uses Thunderbird as the default mail client. I have setup SMTP in the Sage ERP system as the email configuration.

If we send email from Sage, Thunderbird crashes, however, the email does send though. If we reopen Thunderbird, it continues to work, but crashes again, once an email is sent from Sage. Error code: bp-cfdfe3a3-9c4d-487d-9a10-e59510230413

What could cause this and do you have any possible solutions?

Kind regards Maritza [removed phone# from public forum]

I have an Outlook email account which I manage using Thunderbird.

For reasons not known to me some strange folders have appeared in the folder list. The folders in question all have italian names and appear to be some sort of system error folders - Problemi di sincronizzazione.

I do not recognise them, they are empty and are not visible when I view the outlook account using a browser.

I would like to delete them but when I attempt to do so I get an error message "The current command did not succeed. The mail server for account Outlook responded:Command Argument Error. 11."

Any help to get rid of them would be greatly appreciated. Thanks In Advance

Hello! Windows 11 22H2 22621.1555 + Thunderbird 102.10.1 (64-bit) I face a problem with Yandex mailbox with the following authentication settings: smtp.yandex.com:465 SSL/TLS OAuth2 The "Enter credentials" window gives --- 400 redirect_uri does not match the Callback URL defined for the client --- after logging into account. The address in the window is https://oauth.yandex.com/authorize?response_type=code&client_id=...&redirect_uri=http%3A%2F%2Flocalhost&scope=mail%3Aimap_full I removed the client_id but "localhost" is authentic and suspicious. What can cause the problem?

Email attachment icon is small dot with two curved brackets on each side, no paper clip. Clicking on it only offers option to download for offline use. Cannot find download after, not in download file. Cannot open attachments at all. Something changed, not sure what.

I have made many attempts to move Thunderbird from my old Windows machine to my new one. The old machine was running Windows 8.1, the new one is Windows 11. I've exported, then imported using all the different ways listed but can't get all the data. I've had some success doing it one account at a time including my address book and accounts setup information and they are working properly but can't get the folder data for my accounts or any Local Folders for some reason. I don't want to mess up what I've been able to successfully migrate so I'm reluctant to doing a mass migration again. Is there a way I can migrate doing it one folder at a time without messing up the other ones?

I had a large number of e-mails in two separate accounts and all of a sudden, they were gone and I had only a few from today. What happened? I need them for records and such.

I had to change my ntlworld.com password as I was getting a 'Forbidden' message from Virgin Media. Now I cannot access my Virgin Media mail through Mozilla Thunderbird.

so i have a backup local folder where i copy all the mails from the inbox of an account from, and another local folder where i copy the spam folder of an account from, but i am doing that manually, and i don't just delete the now backed up mails. so next time i have to find out first where the cutoff is, before i start selecting and copying again, because otherwise i'd be backing up duplicates.

is there an easier way to avoid duplicates, or a synchronization function that takes care of avoiding duplicates for me?

Hi, I have several issues regarding signatures -

1) how do i make a signature consisting of some text as well as an image - i have created my signature in a new email, saved it as a HTML file and used it as a file for my signature..

2) but when i create a new email - it shows for like a 1 second and then disappears.. doesnt appear in replies or forwards..

3) i tried to instead just use an image as a signature.. again just shows up for 1 second in replies and forwards and disappears..

have set all settings as instructed in the various answers in the forums..

Please assist. Thanks

Thunderbird will not send mail after update the on 5/20/23. Thunderbird did an update on 5/20/23 after which I can no longer send emails. How do I fix this, OR how do I undo the update? It is now at 102.11.0 (64-bit). This is screwing up my business! I have read the FAQs and my settings seem to be correct, but I might have missed something. When I create a new calendar event and add invitees, it used to say SEND & CLOSE, but now it says SAVE & CLOSE. Thanks in advance for any advice.
