Thunderbird Support Forum

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 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.

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!

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 am getting desperate as the harder I try to sort this out the bigger mess I get in.

I think after about 20 years I may have to stop using Thunderbird but I do not know what other Email client to replace it with as they all seem to be confusing.

The archiving problem particularly relates to gmails but I cannot understand the gmail webmail system at all - it seems to sort emails into categories I do not understand or need or want to use.

I cannot send a screen shot easily due to the confidential nature of emails

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?

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?

Hello

Please can you urgently help with this issue.

We cant seem to access our Thunderbird email today. !

message : - "Server outlook.office365.com has disconnected. The server may have gone down or there may be a network problem"

Please advise ?

Many thanks Stavros Kosta

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.

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 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! 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

I have 3 email addresses (2 are gmail addresses) that I have used in Thunderbird for years. My current version is 91.10.0. As of today, I cannot receive or send any new gmail emails through Thunderbird. I don't believe the "automatic update" converted my authentication method to OAuth2.0 because all three of my accounts still said "normal password". As suggested on your website I have tried to change the OAuth but when I go to Passwords I do NOT see "oauth://accounts.googlecom (https://mail.googlecom/)". I tried to delete the passwords and restarted Thunderbird several times but without success.

I get error messages "unable to authenticate to outgoing server. Please check the password." I have changed the password but again no success.

I have checked that cookies are turned on for all sites.

Do you have any ideas how I can correct the situation so I can receive and send emails again?

Hello, have the latest version of Thunderbird (102.5.0.) in Windows 11 Pro. I'm using 6 IMAP accounts there.

I want to stop check mails automatically in one account, so I unchecked: - Check for new messages at startup - Check for new messages every 10 minutes - Allow immediate server notifications when new messages arrive

Problem is thunderbird still checks for new mails of that account and shows me notifications. What is bad please?

Tried to clean install of thunderbird, didn't help it. Thank you

Struggling with TB constantly "downloading" x 10s of thousands of 10s of thousands of emails (all of which are downloaded), and the programme grinding to a halt. Have set the inboxes to a retention policy of 2500 total. So shouldn't even be trying to DL more than that. Seems to mainly manifest when I compose an email (exactly the time that the sluggishness is a problem). Have done the usual compacting/deleting * files.

This is getting to be a real issue now. I wonder if there's any paid support channels that can deal with this?

Keeping got massage: The folder 'Inbox on parkerlin@hochien.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

Have clean up all In box mail and compacted it, but still has same problem .
