Thunderbird-Hilfeforum

My friend has been using Thunderbird for a long time. Recently I installed her new PC and restored her account profile using the profile folder on her old PC. So far so good. The problem is that her mails are not organized in folders on the mail server but she has a whole collection of folders in her Thunderbird mail client and is concerned about loosing her mails if the new PC (or the disk) would crash at some point. Of course she could just re-install Thunderbird after fixing the crash problem and sync with the mail server, but then the folder structure would be lost. First I considered using a back-up program to keep a back-up of her Thunderbird profile using cloud storage. My second thought (should have been my first thought...) is that she already has a back-up, namely the mail server. The ISP does a better job than any local back-up program to keep her mails safe. Only the missing folder structure remains a concern. So here is the question: if I change the setting to sync all folders with the mail server, what will happen: 1 - the folders in Thunderbird will disappear (only the folders, not the mails) because there are no folders on the mail server 2 - the folder structure from Thunderbird will be mirrorred on the ISP's mail server. Which one is it?

I currently receive all messages sent to me including those from Comcast but I can't send messages to any email address. When I logon i get the message: Enter Credentials for my email address on imap,comcast.net. I read the document: Switch from POP to IMAP account > Create the IMAP account. I never saw the window shown on page 3 of the document. The other day I got a message that the IMAP account was already created. I then edited the my SMTP account.

Unified Folders in Thunderbird 115 for mac no longer works. Useless! Computer Tech specialist here and have been using Thunderbird for ages. With this latest version, the inbox, sent, etc etc etc no longer display as unified. The Unified Folders category when ON shows as its own item in the left column with a single empty inbox! Scrolling up and down to each account for each subfolder is a waste of time!!! Hope you fix this ASAP!!!!! Unified folders works fine in 10.12.13 but I cannot got back to that due to your system.

Delivery Status Notification Does Not Work!!! and hasn't for about a year~! I have the latest version of Thunderbird, Ver 103.3.2 (64 bit) ! I am wondering if there if it's my Breezeline email server or is there an issue within my About:Config properties?

I currently have Thunderbird set up using POP but would like to change to IMAP to sync with my other devices. If I change from POP to IMAP, a. will that affect the emails that are currently showing in Thunderbird and b. will the emails that are in Thunderbird then appear with my other points of access?

I'd like to suppress displaying message Subject in the folder contents pane. (I'm in vertical view and would like the message contents pane to be wider. To accomplish that I'm willing to sacrifice listing the Subject in the folder contents pane. Tbird doesn't list that as a column I can select or deselect. Any ideas?

The real goal is to make the folder contents pane narrower. But it seems to not allow me to make it any narower than it is. A9(I can widen it, but that doesn't help. Is there any any to change the minimum width Thunderbird has set for that pane?

I have, very reluctantly, had to stop using Windows Live Mail, because gmail will no longer support it. It was a great email program and it did everything I needed. Thunderbird would seem to be the nearest thing I can find to replace Live Mail - but there seems to be some quite staggering basic functions that are missing from it. Maybe I'm alone in wanting to include a picture or two in my emails..? - not as attachments, but as part of 'the visual letter', within the text? Live Mail must be 20 years old at least - but in Live Mail I could insert an image; drag the corners to resize it; add a box rule if I wanted to; and send it on it's way. In 21stC Thunderbird I can, with many a dialogue box, insert an image... but even when I've worked out how to 'resize it', it doesn't actually reduce the file size of the image sent..! So a 7MB image, when 'resized' to something less than 1MB... still actually gets transmitted as a 7MB image - and takes forever! So my question is. How come an ancient, now almost defunct program like Live Mail, is twenty times more agile and user-friendly than 'up-to-date' Thunderbird? And before anyone mentions 'add-ons' - Live Mail did all of this straight out of the box! No 'add-on' searching or anything else required. But maybe including a picture or two in an email is a fairly revolutionary concept? With thanks for your thoughts.

I am running Thunderbird version 115.4.1 on the Windows 11 system. Having Thunderbird active (even in the background or minimised) stops the Windows key from working. How can I get the Windows key to work normally without closing down and exiting Thunderbird?

Hello! I accidentally hit 'K' with a thread selected, and so got a message at the bottom of the screen saying that replies to the thread will not be shown. This is the same situation as in the now-archived question [[Accidentally pressed "K" on an email - can no longer find it|https://support.mozilla.org/bm/questions/1380096]].

I'm now writing because I *was* able to select the option to display ignored threads described in the reply to the question above – so that I can, at least, now see the thread that I accidentally ignored without meaning to. But I'd like to actually fix the problem and un-ignore it.

I've read the support article on Ignoring Threads, but what that article describes – namely applying 'Ignore' to the same thread so that it toggles off to unignore the thread – isn't working. I also tried quitting Thunderbird entirely after doing that and then reopening it, but I can still only see the thread if 'view' is set to still display ignored threads; when I remove that view instruction, the thread disappears again.

Does anyone know if there's something else I should try? Or is this maybe a bug in Thunderbird that needs to be fixed? Thanks so much in advance!

Please advise ?

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.

I have purchased the Owl addon so that I can use two Microsoft 365 email addresses in Thunderbird, I have set them both up and they appear in the side panel with my other email addresses but only one of them will send or receive emails. Please could someone supply up to date instructions on how to set two exchange accounts up. Thank you

The spell checker is constantly using English (USA) and not English (UK). No matter what I set it to it reverts. I suspect every time there is an update it does this and it is extremely annoying for anyone living this side of the pond (In the UK).

PLEASE can we have English (UK) by default. I notice when you add it to the list of languages in settings the USA version cannot be deleted.

Hi, Looking at the folders under my email, I see: 1 Inbox, 3 Drafts, 3 Sent, 1 Archive, & 1 Trash. How do I get rid of the extra Drafts and Sent folders? See the image below. The second and third are empty.

Yes :) there is more to it. Here are the details. I know how they got there and I did that to myself. I keep my Thunderbird Profile Data in a MS OneDrive shared folder. Yes, I know, this has some risk. However I work overseas 1/2 the time and use two different computers. This allows me to have each computer on a POP account and still have one set of data (and have Pop Accounts on my phones). I have been doing this for more than a year, and have not had any consequences beyond the above. I understand IMAP accounts, but do not use them for very good reasons, please do not recommend that.

I am generally careful to close T-Bird and then wait for OneDrive to update (I have learned how to "force" OneDrive to do so) before restarting the other one. There have been several occasions where I did not do that. Usually, I just get a bunch of repeated emails and some extra "computer named" versions of the data files. Once in a while, another folder Drafts and Sent folder has appeared.

Thanks in advance.

I deleted a duplicate email but left the original in Thunderbird. The next time I downloaded emails from the server, the email that was a duplicate on Thunderbird was deleted from the server. Why?

I have Thunderbird setup to leave the emails on the server until I delete them. However, I only deleted a duplicate of an email. Should this have happened? If so, how can I avoid it if I want to clean up duplicate emails on Thunderbird? My mail server is a POP server, if that's important. And I'm using the Remove Duplicates addon

Hi, As of yesterday I am unable to send emails out. I keep getting this message below. I have gmail on same computer and that works fine. I am able to receive emails but can't send. Please help

Hi! I have a lot of IMAP mail account and want to store all relevant mails in an lokal account stored on an local folder. So I created an new local account and selected in the account settings at the option Message Store Type "File per folder (mbox) to store each folder in an separate folder an the local file system.

The Account Name: RS_Mailablage_Zentral Local Directory .....\RS-Mailablage_Zentral

Now I want to move/copy some mails from the IMAP-account to the new local account in an new created folder. But it doesn´t work either by drag & drop nor by using the the option "Move to" in the Message-menu. It doesn´t work in the troubleshoot mode.

In the local directory I found all the created folders from TB as directory foldername, as directory foldername.sbd and as file foldername.msf. You can find some screenshots at the uploaded pictures.

Please can you help me to find a solution.

I use TB version 91.13.0 (64-bit) on Windows 10 Home version 21H2
