I run my BTinternet mail account via Thunderbird and would like to run my two Gmail accounts via Thunderbird too. Do I just do that by clicking on the + New Account button, please? I'd hate to lose access to my BT mail by doing that. (Switched to Thunderbird from Outlook a year ago and have never regretted it!

My question is, whether or not the android Thunderbird will interact with the windows Thunderbird I have on my laptop. On my laptop, I have Thunderbird redirect emails into various folders. On my cellphone, I'm currently using Fairemail but it's not aware of those folders on my laptop which is a problem when doing a search on my cell for a specific email, if the email I'm looking for has migrated to those folders on the laptop. Thanks in advance, Phil

I can send but not received emails from my several accounts. I know there's email on some, as I can see and read them with Mailwasher.

I have noticed previous posts here with the same problem, but I haven't seen a viable solution. (I'm on a new computer since last week.)

I just upgraded (reluctantly) to Win11 on my desktop, and my POP Thunderbird account did not survive the upgrade. I had to switch over to a new IMAP Thunderbird, losing all of my POP folders (which are still on my disk). Just not, apparently, accessible.

Anyone have info on how to re-access or somehow get them into my IMAP install?

I have Thunderbird installed on a Surface Pro running Windows10 and on a Surface Pro running Linux Fedora. When I use the Windows10 computer to prepare a Thunderbird export file for the profile, the Fedora machine Thuderbird import command will not read it.

The Windows10 machine has Thunderbird 147 and the Fedora machine has 146. Is the difference in version responsible for the failure to import the profile files? Or is it something else?

If the difference is the version of Thunderbird, then how do I get 147 on my Fedora machine?

If it is something else, what do I do so that I do not lose saved emails and calendar data from 147 version when I am running the 146 version?

I have TB setup to allow customstylesheets with userChrome and userContent.css files generated. I have userChrome setup to my liking. Now I want to modify the userContent.css file so that I can set the background color of almost all elements is #222226 except for email text, hyperlinks, and imbedded images. I have this setup now in userContent.css:

body { background-color: #222226 !important; }

{ color: white !important; /* Changes font color to white for all content */ }

This changes most elements the way I want but it also flips the color of other HTML content, embedded images for signatures and other html content so its inverted to unreadable white content with white text. Is there a way to set it up so that HTML content and images are not inverted?

Is there a way to have TB auto delete Trash msgs older than a specified number of days. I don't want to just empty all the Trash folder, but I would like to be able to tell it to empty all messages over 30 days, or 42 days or whatever. Suzanne

Since we needed to upgrade 2 PCs to Windows 11 (1x Pro & 1x Home) nothing works anymore with Thunderbird. It has MASSIVE and unsolvable problems to connect to our Gmail account via OAuth, Not only will it ask every single time again and over again to allow the connection, but moreover even after granting access it still can NOT send (SMTP) or save or even receive (IMAP) emails. It is maga frustrating and I am currently after days and days spend to unsuccessful fix the problem are at the point to looks for a more reliable alternative (if there is any). Just as background: Our Gmail account is about 14GB big, the local Thunderbird folder around 100GB; so yes it's big, but that's another problem, there are no easy or straightforward off-line archivers any longer to effectively and still easy accessible reduce the local archive.

I've (finally!) managed to set up a new account on my new PC (having found the required password, a long string of letters - where did that come from? - I would certainly never have chosen that and I was never informed of it). I also successfully managed to transfer my Profile from the old PC to the new one (thanks to your helpful article. However, While I have thousands of 'sent' messages I only have a few in my inbox and sub-folders (i.e. today's). (I originally used the recommended server settings (?IMAP) I was offered but then changed to SMTP/POP which is what I always used before without problems.) So - I go to 'Import from a Thunderbird profile' and it shows me the Profile Name and Directory details, but then says 'Nothing can be imported from the selected source' - but doesn't tell me why not, nor what I should do about it! Given the Profile has transferred successfully, why can't it be accessed? Any ideas appreciated. Thanks, David Collins.

Since the latest update to my Thunderbird installation (Windows 11), my previously created Mailing Lists have stopped working after always working well. Thunderbird Release: 140.7.0esr (64-bit)

I now get the message below when I try to send an email using a mailing list address:

• • • Committee <*** Committee members> is not a valid email address because it is not of the form user@host. You must correct it before sending the email. (Name partially starred out for security).

Am I doing something wrong?

I have one account in Thunderbird that pop's emails from a Yahoo account. If I delete a message in Thunderbird it goes to a local trash bin and on default stays there forever.

I want the emails to be deleted after 40 days in the trash bin. See picture. But it looks like it works exactly like it's described.

Messages are deleted from the trash when it's 40 days after they were originally send. If I delete a message in the inbox older than 40 days it goes to the trash and is immediately deleted from it.

I tried deleting several messages older than 40 days.

The counter of the trash increases for a split second with 1. If I look in the trash the deleted message is not there.

In my trash there are only messages "younger" than 40 days. At this moment the oldest is from December, 14 2025

Yes it works like the retention policy tells it should work. But this different from what I expect from trash folders

I have an email filter set for a domain that has been sending many spam messages. It was working but now they have started to use my name portion of my email address in their email address. For example, if my email address starts with bobp@ then the email address at the top of the email is bobp@ncqkl.com. The domain is real.

The only option for the first column of the filter I am aware of that can be used is "From", "Contains" and "Email Address". I don't believe Thunderbird allows domains. I have tried ncqkl.com to no avail. Somehow they are getting around filters by using your email name portion. They were also using multiple different addresses all with the ncqkl.com domain.

Is my best bet to use the adaptive spam system? I haven't really used it in the past as I haven't needed to. I don't get much spam usually as I don't have much of a presence on the net. Just lately the amount of spam has increased considerably.

Please help with changing font for outgoing emails. I have clicked on Thunderbird settings, general, then fonts - Ariel and 15 is selected but another serif type font is produced. Very puzzled!

Hi,

I cannot see any formatting bar in my "new message" window. I cannot change my text format, I tried to change a lot of settings but nothing seem to work.

I also cannot customize my signature - the html just shows weird and not as expected

Thunderbird refuses colored text on new Lenovo 17" Idealpad and adds asterisks not written by the author. Example message test: bbbbbbbbbbbbsssssssss ggggggggggggg***234*5678,56 *<==============* The written numbers and the arrow were colored red. No asterisks were written in the message sent. When writing, colors appeared correctly in messages with no asterisks on screen. However, no colors appear and asterisks are added in recorded messages sent and received on the PC. The Lenovo PC works OK in general, so it must be a Thunderbird configuration/function problem on my PC as the message is correctly received with colors without asterisks on my mobile phone. Can you help me correct this PC anomaly? Many thanks
