Thunderbird Support Forum

Hello, i try to customise the thunderbird mail colors, but can't find any settings to that. I want to change the colors for "marked as -> unread" messages and the color for new received messages. Can anyone tell me how to adjust this? I tried to add the "userChrome.css" file in the self created folder "chrome" in my profile directory, but nothing changed. Can someone help me? I use Ubuntu 22.04.4 LTS version and the thunderbird version 115.6.0.

I have a <something> that creates a daily sunrise and sunset entry time in my diary. It isn't an addon as far as I can see. It's not a prewritten list, but seems to create its entries dynamically when I first look ahead to a date- filling all the days with the correct sunrise and sunset times. The normal reoccurring event options don't appear when I delete one. i.e. doesn't offer me the option to delete all the events. I have no idea what I did to set this up ( it must have seemed a good idea at a time). I can not see any subscription that would account for it. I've checked all my accounts on my devices. Thunderbird/Betterbird on my main PCs and Outlook.com on my iPhone just in case I brought it in to TB that way ( which seems unlikely). Nothing. Clearly something is working away generating new sunrise and sunset times to display in TB. But I can't find any way to kill it off. I must have found a sunrise/sunset app that does this, but I have no idea how or where. Any suggestions. Either where it might be hiding in TB or where I can track it down and look for instructions.

Edit: Is there any kind of logfile that tracks such events being created?

Hi,

I repaired my inbox yesterday. I had many messages still in that inbox but after the repair I only see 5 messages. I looked in the directory my profile points to for my email and can see a large Inbox file - but I also see a very small Inbox.msf file. It is almost like the process of rebuilding is pointing to another Inbox file. See the picture attached.

I even tried to take a previous copy of the Inbox.msf file from a backup (it was 800 kb). I deleted the old Inbox.msf file and replaced with the larger 800 kb file. When I opened Thunderbird, it started to something: "Building summary file for inbox" and about a minute later those same 5 emails show - instead of the full Inbox I would have expected.

Is there anyway I can re-associate the Inbox.msf file process rebuild/repair to the correct Inbox file (the one that is 737 meg in this case)? I sure would like to get my inbox messages back (and file them away i/o leaving them there vulnerable to this kind of problem in the future).

Thanks in advance,

Patrick

Outlook email accounts are duplicating and asking for passwords which are in the password manager. T/B does not accept the entered password. Gmail accounts are also duplicating and adding weird passwords. Just started last week. Probably has something to do with the new Microsoft Authorizarion rules. It is a mess. I have been a lifetimme used if Mozilla and Thunderbird.

Tell me how I can continue to use thunderbird with the above account and also Denis.Clarke.hotmail.com after September 18. I have 4 individual historic E mail accounts and thunderbird joins them together. What do you need to do? To deal with threat below.

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Hallo, durch eine Unachtsamkeit habe ich das Hauptpasswort (Primäres Passwort.) von Thunderbird gelöscht. Ich finde auf den Hilfeseiten keinen Hinweis wie man da Passwort zurücksetzten kann. Dadurch komme ich nicht mehr an meine Mails. Freundliche Grüße

I have a Windows 10 pc, which is current with all Microsoft and manufacturer (Lenovo) updates. Thunderbird won't run since the last update. It just gives a message saying, "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now?" After several reboots, I have given up. A support forum solution from 4 years ago recommends deleting a file (global-messages-db.sqlite) at a location (C:\Users\user\AppData\Roaming\Thunderbird\Profiles\8charstring.default) that seems not to exist (hidden?) on my pc. What do you suggest? Thanks.

Hello: t-bird 115.12.2 esr dev build. W11p laptop. Drag & drop (also paste) for putting a file inline for a msg do not function "any more," this has functionned in earlier versions. I can only attach the file. I have changed config ed settings mail.inline_attachments & mail.inline_attachments.text to true & restarted t-bird, to no effect (no inline). This is for a simple .rtf of 340 bytes (yes, very small). Please advise. Thank you.

A new problem since July 1, 2024 Thunderbird keeps crashing on start-up when checking for new mail. HELP!! Crash ID: bp-e8be7291-7fe9-41c0-bd21-45d860240702

I have received an email from Microsoft informing me of changes to its authentification procedure. As from Sept, to continue using Thunderbird to access my outlook/hotmail accounts, I have to change the authentification method to Oauth2. The reasons and changes required are detailed here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 I have 2 problems. 1. imap-mail.outlook.com - I can change my authentification method to Oauth2. However, when I then try to access my mail via TB, I get an error stating that the server imap-mail.outlook.com does not support the authentification method! (see image) 2. Outgoing Server SMTP There is no Oauth2 option available to choose!

Can anyone help? I am using the most up to date version of Thunderbird 115.12.2 (64-bit).

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide provided to update Thunderbird, but my version of the program does not have OAuth2 as an option. My outgoing server is smtp-mail.outlook.com, but OAuth2 is not an option in the dropdown for authentication method.

Error message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <ec2-54-219-72-248.us-west-1.compute.amazonaws.com[54.219.72.248]>: Client host rejected: NO THANKS. Please check the message recipient "patrick.gilroy@harmonydesigninc.com" and try again"

Occurs regardless of recipient, whether replying to an incoming email, or composing a new email.

Not always, but frequently when I delete an email from an inbox, the other emails are hidden for awhile. This occurs whether I am pressing Del while the email is visible, or pressing Del with the email selected in the Inbox. If, however, I immediately open another folder and then re-open the inbox, all emails are instantly visible. Am I doing something wrong, or is this a "feature"?  ;-) Regards, Dave

have been using Thunderbird mail for about 3 years. It’s template selected the incoming and outgoing servers and ports etc..successfully. I've been connecting to Prodigy mail/ATT I had to change the battery and it doesn't work anymore. Can you help ???it checks the password until it shows an error message that the servers password or etc are wrong. I know the password is right since I can log in directly. Messages :

1- Configuration found in ISP Database

2- Checking Password (for a few minutes

3- Unable to log in at server..probably wrong configuration username or password

4 then nothing

Worked great before battery change

I received a notification from @hotmail and @live that I won't be able to receive or send mail after Sept 17th without taking action - what steps should I take when I don't have Microsoft Office 360?

We have recently moved to a new mail server. We currently have about 20 Thunderbird email clients on Windows in an office location and a macOS home machine. On all machines email is configured to use IMAP on hostname.com port 993 SSL/TLS with Normal Password and SMTP on hostname.com port 465 SSL/TLS with Normal Password.

The home machine is working 100% with no issues, it does have a much faster and lower latency internet connection than the office machines.

Many of the office machines are experiencing intermitent SMTP error messages when sending, intermitent, "unable to save mail in the Sent folder of the Inbox", messages and intermitent unable to move messages between folders.

I have checked and double checked the settings on affected machines - however, I believe a settings issue would result in nothing working, not intermitent functionality. Plus all is working fine on the home machine with the same settings (different OS, but ports and security settings all dictated by server).

With one client behaving properly, the server likwise behaving properly when addressed by the working client and the intermitent nature of the problems we are finding, I suspect we have some sort of network issue. Somthing timing out or a firewall/AV software causing a delay.

I have increased mailnews.tcptimeout on affected machines to 250 based on a forum article but this has had no effect (No idea of units here but if it is seconde then I am not supprised - the SMTP errors, when they happen are almost instantanious).

Any ideas on how to trobleshoot this problem further - The problem seems to get worse through the day, although that may just be peoples tollerance of an intermitent issue going down.

Why won't Thunderbird send emails when connected to NordVPN? I have spoken to Spectrum and NordVPN and both of them have suggested that Thunderbird is the issue. I have confirmed that my SMTP settings are correct. I can send and receive from the Web client's site. I have turned off NordVPN and the sending process works as expected. However when I turn NordVPN back on, my outgoing emails are blocked.

Changed Gmail.com password and now Thunderbird will not login even with the new verified password. I have tried all recommendations on the internet and nothing works.
