Thunderbird Support Forum

Hi, I have used Thunderbird for many years and always liked it. I would like to know is there a way to tone down the brightness of the white message pane in email ?? It is very bright and glaring. Any white anywhere else I go is just fine. Thank You,, Banyarola

Hello, I've found this article [[Knowledge Base Article|https://support.mozilla.org/en-US/kb/maildir-thunderbird]] which substantially says that the use of maildir is deprecated. Has anything changed from the time that article was posted? I'd like to use maildir, it seems to me a more rational way to store e-mails (and it's also better to make incremental backups).

Thanks in advance Denis

I have been using three email accounts on Thunderbird, all for a long period of time, and all without any issue. Recently the one listed below has not been backing up, and I receive this message. I am not techie at all, so any response needs to be dummy down to a 5th grader level. Thanks!

"Non-overridable TLS error occurred. Handshake error probably the TLS version or certificate used by server mail.q.com is incompatible."

I have 4 accounts with different names but all with the same domain name (name1@samedomain.com, name2@samedomain.com ...). The first one set up perfectly and works. The 2nd and the 3rd can't retrieve mail from the server (didn't try the 4th yet). The SSL ports are the same for all. The passwords happen to be the same for all. (I haven't tried changing the 2nd and 3rd passwords as that seems unlikely to be the problem.) When initially setting up the 2nd or the 3rd I get a "Sending of password for user name2@samedomain.com did not succeed. Mail server pop.yyy.zzz responded: [AUTH Authentification failed." I've checked the passwords on both the client and the server ends multiple times and they are the same. Then, of course, periodically I get a pop-up with "Login to server pop.xxx.yyy with username name2@samedomain.com failed. When I go to the Account Settings screen with the 3 accounts and click on each Server Settings one after another, the only thing that changes is the User Name, yet the first account receives mail and the other 2 don't so everything is correctly set up. As an aside, I CAN SEND emails from the 2nd and 3rd accounts but can only RECEIVE and SEND from the 1st. Any help appreciated.

Bug forever (years, versions, reinstallations).

Failure by filters whose action is to DELETE. As stated in subject. Uncomplicated.

Other filters work (they distribute msgs into specified folders).

I have had a few emails that did not show up in the inbox listing, so the message count at the top indicated more messages than were listed. Doing a search showed them, and by moving them from the search results to another folder, and then re-searching and moving them back, caused most of them to appear. But not all - I still have a message count of 20, but only 19 listed, see photo 1. Photo 2 shows the hidden email (from Barry Chandler). So the email is there, it's just not visible!

I have 4 different email accounts, all managed by IONOS. These have all been set up under thunderbird OK. But when I send an email from 1 of these email accounts I always have to enter my password for that a/c. With all the other accounts, this is not necessary. I do not use Thunderbird or Firefox password managers. I assume that I must have made an error in setting up the outgoing details when setting up that particular account in Thunderbird, but I cannot find a way of checking if that is the case.

Hello,

When I try to: 1) click and drag an email's attachment to my desktop, I get an "Unspecified Error" dialog box. 2) use the Save button (on the bottom right of the attachment line), the saved file is zero size. These occur if the email is shown in TB or in a separate window.

Workaround: When I click and drag (or save) the EMAIL to my desktop, the resulting file is an '.eml' file, which I able to "open with" TB from Windows Explorer -- this attachment is valid, if I click open or save it.

I am running Windows 7/TB Supernova 115.3.3 (64-bit)

I don't deal with many email attachments, so I am okay with the workaround, but would like find a way to correct this issue.

Thanks, Jim

After updating Thunderbird to 115.5.2 I receive an error when I check (get) messages of my gmail account : 'The STAT command did not succeed. Error getting message number and size......'. However, the messages do come in and so the error turns out false. since the authorization (OAUTH2) credentials are accepted.

I have my server settings check messages from startup; every 5min; automatically download new messages. That works fine. Again only when I goto "Get Messages" the error shows up.

What is wrong here and ho do I fix this? Thank you

Hi there, My preview panel is working very badly, it either shows the content of the email or is completely white. What can I do to remedy it? - In some cases the emails appear in very strange codes, thousands of lines like this (iVBORw0KGgoAAAANSUhEUgAAAPAAAABGCAYAAADyxhn6AAAAAXNSR0IArs4c6QAAAARnQU1BAACx jwv8YQUAAAAJcEhZcwAA) - in other cases, totally blank - in other cases it's everything ok It's working fine, receiving and sending all emails.

I have windows 11 home edition. Thanks

Question: How I can access shared folders in Thunderbird?

Office 365 business. I can access admin portal etc:

portal.office.com/adminportal

And also I can go to Exchange admin portal via this. So, in my opinion I can use all deep settings also.

Office 365 licenses (full) for name.lastname@company.fi. Portal show "Office 365 business standard".

I create also shared folders. Today shared folders found from "Teams groups". Log in to portal.office.com/adminportal, "Teams-Groups", and then "Shared mailboxes".

My conf: Office 365 business standard found name.lastname@company.fi. ("john.smith@company.fi", "alice.brown@company.fi" as example.)

Shared mailboxes sharebox1, sharebox2, so, it is possible receive email sharebox1@company.fi, sharebox2@company.fi etc. (in real life share box names are bookkeeperteam@company.fi, orders@company.fi, helpdesk@company.fi etc etc.)

CONFIGURATION IS FULLY WORKING. It is, in Outlook it is possible receive and send emails, shared folders with messages are available etc.

------ 

HOW I can add shared folders to Thunderbird? Clean install tested.

1. LIcenced mailboxes work properly in Thunderbird. Tested.

name.lastname@company.fi:

Server: outlook.office365.com, port 993 Username: name.lastname@company.fi Connection security: SSL/TSL Auth: OAuth2

And smtp: smtp.office365.com, 587, starttls, oauth, name.lastname@company.fi.

This configuration work properly, and it is possible receive and send email from Thunderbird.

SHARED FOLDERS

It is not possible add shared folders.

Server: outlook.office365.com, 993 Username: name.lastname@company.fi/sharebox1 (where name.lastname is real working account name, just same as in position 1- working account. Also this sharebox1 work in outlook.) Connection security: SSL/TSL (no difference is it this or stattsl) Auth: OAuth2

(I am sorry, all my systems are native language, so I must translate---)

OK: Now I try use this shared folder. It is visible in Thunderbird. But immediately thunderbird open Browser and ask password: "name.lastname/sharebox1", wrtite password. Now I put same pw as in this account (name.lastname..). "Password wrong." I try empty password. I try account password.

SO: HOW to add shared mailbox in Thunderbird? This information "name.lastname/sharebox" not work. Is it any other method? Or any Exchange setting modification make this?

For a few weeks I have had a new problem on my new Windows 11 Lenovo laptop, and also on my wife's older Dell laptop. We have been using Thunderbird for years without major problems. I loaded the latest version of Thunderbird on my new laptop and it seemed to work ok at first. Now I have a problem with intermittent failure to send normal emails on Thunderbird. My wife has noticed the same problem on her laptop Windows 11. I asked iPrimus support (who are supposed to support Hotkey) but they say it is not their problem but Thunderbird's. We RECEIVE emails ok, and sometimes pressing SEND will work immediately, sometimes on the second press, and sometimes not at all. This generates a message "-- Unable to authenticate Outgoing Server (SMTP), smtp.hotkey.net.au -- Check password and verify authentification method in Account settings/Outgoing server SMTP" We both use Trend virus protection.

Account name: mail.hotkey.net.au Outgoing Server: smtp.hotkey.net.au Server Settings: Server name pop.hotkey.net.au

                             User name is my email address

Here's the technical details: Win 10 Home 22H2 Build 19045.4291, Mozilla TB Thunderbird Version 78.4.0 Build ID 20201019003438 Distribution ID Update Folder C:\ProgramData\Mozilla\updates\8216C80C92C4E828

This AM I was able to check / get e-mail five (5) or more times. Then clicking 'Get Mail' displays; connecting to mail.duo-county.com After 15-20 seconds connection to server mail.duo-county.com; Timed Out

I know of NO changes to any setting. When our e-mail was set up, we were told to set we were told to use Pop-3. Our ISP, who does NOT use NOR 'know' TB said we should be using IMAP, could NOT help review nor doing anything without risking ALL folders - files-data!

PLEASE help ASAP. Since we can't get - check mail I'm LOST! My spouse's e-mail is wpj@duo-county.com

I am having older Thunderbird 102.13.1 and when i input into a search field for example: 37.19.223. or "37.19.223." or "37\.19\.223\." it always stupidly and uselessly output tons of messages that contains unrelated IPs:

([76.223.177. [10.223.144.96]

highlighting number 223 as if i have searched just for this number 223

I think that it is reasonable to expect from TB to output only search results where email contains 37.19.223. without any hack, escaping or regex or whatever (if you know a workaround, please kindly share it).

Maybe newer TB works better? Anyone tried? If it works same way, can you please kindly ask developers to fix this?

Hello, All

I need major help, please.

I am getting the attached messages when trying to send an email. Thunderbird worked perfectly yesterday morning, but then would not send any emails. I get emails, but cannot send from my 2 accounts.

I am on the latest version of Thunderbird, Supernova 115.10.1

Also, I cannot find out where to change my password for the accounts, because at times I need to fill in a password. I can't find it.

Thanks in advance for any help.

Best, Leslie

hi all guys ... I'm experiencing several issues with oauth2 authentication, and I never had any issue before February the 2024 ... at the beginning the only account I have was not working was a microsoft account, so I thought it was "because of microsoft restriction"

but now, little by little, all my accounts requiring oauth2 authentication are failing, and I don't know were to check ...

I do NOT have any httpd/apache server running on localhost

I already tried changing things like general.useragent.compatMode.firefox or network.protocol-handler.warn-external.http network.protocol-handler.warn-external.https

I also created another blank profile ... but again ... not way to make it works ...

cookies are permitted ... javascript is enabled ...

the result is always the same ... a blank page when I try to do any oauth2 authentication ...

if I manually copy/paste that link in Firefox/Chrome it perfectly works, so it's not a network connection issue ...

from what I can understand, it seems to be related to the "built-in browser" in thunderbird, that for some reason does not work "as expected" ... If I try to click on any link for example in the settings page

like the "learn more" link of this option Send web sites a “Do Not Track” signal that you don’t want to be tracked "learn more" thunderbird does NOT show anything ...

something is broken, and I can NOT understand what it is ...

is there anyone with some good advices?

please let me know

thanks in advance

Stefano

Collecting mail one day, I received a Thunderbird message 'compact now'. After the compact process, some mailboxes are missing. How do I re-instate these deleted mailboxes?
