I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.

I even REMOVED the email account and re-added it making sure it was OAuth2.

But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.

I am tempted to shut down all Microsoft email accounts and switch to Gmail.

I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0

Any idea how to stop these prompts?

I like Thunderbird much more than any other email program I have ever used, and would like to keep it

So, I had to delete my wife's email account (and I know people cringe when that's done), because no matter what, I could not get in with any password and Thunderbird was acting strange in general. I created a new account but no matter what it will not take any password I put in. It just continues to circle and goes no where! How do I create this account easily, as I have done in the past, and what do I do about Thunderbird not accepting ANY passwords? As I said.....no matter what I put in, the the password section it doesn't take. Its like this: Name: Email address: Password: Once I put in whatever password I'm using it just continues to spin (or think) and goes no where. Can someone please help me here? I would so appreciate it. I'm not a computer dummy, but Thunderbird is sure making me feel like one!! Thank you in advance!

There is a feature in outlook that I use all the time at work, where if I reply to a message in my inbox but I had already sent a previous reply, it will let me pick up my reply to include in the thread, that I reply to instead.

It would be great if Thunderbird would do that for my personal emails.

I forgot my email password and am not able to sign into my "secondary email" lotsof families@comcast.net. In trying to reset my password I managed to delete all messages in this email inbox!

I use Mozilla Thunderbird as an 'app' on my PC (Windows 10) in order to access my Virgin Media mail - @ntlworld.com. In the last fortnight my outgoing e-mails have not been sent, and a message 'Sending of the message failed. An error occurred while sending mail. Authentication Required (VM401)'.

After much time searching for solutions on the internet, I understand that it was because Virgin Media now require a two stage authentication, and I would need to generate a new password specifically for e-mail apps like Thunderbird.

After a great deal of grief, I eventually believe I have now generated this 'app password', but do not know how I can update Thunderbird (if that is what is required?) to include this password. I have updated the SMTP settings, but there appears to be nowhere to include this password.

I would be grateful if you could cast some light on this problem.

I am unable to retrieve my emails from my AT&T account, keep getting an error that inbound.att.net system error (SYS/TEMP). It keeps asking me to enter my password, but will not accept my password for ATT. I can access my emails directly from ATT.net, so that is not the issue and have checked to make sure POP is correct.

Thanks for the help with the screenshots David. Here are the 3 screenshots 1.) Error message on bottom right. 2 & 3) Incoming and outgoing server settings. Looking forward to solving this issue!

I keep getting error messages like below..... up to 50 a day where my Thunderbird is not syncing with my hotmail email. I can not force it but just wait until it happens to automatically sync. It keeps getting worse every week and I just got a notice from Microsoft that they will no longer accept third party programs that do not support modern authentication after September 16. I love my Thunderbird. What can I do to ensure access to my hotmail with Thunderbird?

I've lost my email program dictionary at last auto update. I need to delete program and reload but I don't want to loose my email folders. By deleting program, will this effect my email folders? Thanks

Why don't you have a version that once you push it out, you just leave it alone, except for any serious security updates. I, and I'm sure many others, have very simple needs in an email client, and all the added whiz-bang features serve to only make it harder to use for many of us. Or, alternatively, make it modular, start out with the basic client, and then allow users to add any features they feel would be useful for them, instead o having a bloated application that 90% of goes unused.

Message from Microsoft using Thunderbird. What do I need to do? Thanks

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

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.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

Hi all,

I'm writing an email reply and wanted to answer questions in a red font. So, my top line reply was "see below in red" and then I wanted to type Yes or No in red after each question. I couldn't even copy and paste from a word document with the font in red.

In Thunderbird, I clicked on the color checker, typed in FF0000 for the color code and clicked yes. Then the color selecter boxes on the menu went right back to white.

Any ideas?

It must have been one of those nutty "...something I did" things that made a second account identity appear one day. I use a Unified Folders mode exclusively, and the subject account is my primary account (identical to the first Unified listing), but some action on my part made it pop up below as well, just above 'Local Folders.' The only subfolder under this redundant appearance is 'Templates,' which is empty. The unwanted appearance starts out in a blue font, but turns black (as shown below) once the 'Templates' folder is clicked on. Can I get rid of this somehow?

I moved some emails to a folder from the inbox and now they are not displaying. when I search them I am able to find them and can be read, the search indicates that they are in "the new folder" all mail and important. This has happened before and I have not been able to resolve I am assuming there must be a setting I have activated/deactivated but I've no idea what. I am FAR from tech savvy so please give any answers in as simplistic form as possible. Thanks Matt

With about 60G of accumulated e-mail in several Microsoft accounts, I moved all accounts into T-bird and put most in local folders. This somehow became over 600G in size. Everything works and compacting seems to be getting done since it's been working some weeks now. Yet this ten-fold increase in size is unwieldy and very difficult to backup. Perhaps related, I notice that M'soft's "new" free Outlook app is present and perhaps running on this computer. And all the e-mails I send from my main Hotmail account are listed twice in the T-bird sent folder. About half of the times I start T-bird, I get a message saying that login to server outlook.office365.com with username xxxxxxxx@hotmail.com failed; the other accounts never do this. T-bird offers to retry, but that usually ends with a repeat of the same message. I've learned that if I let it open, with time, the e-mails do appear, though I don't know how or why. I've also been using Libreoffice successfully for months now though I doubt that anything to do with this. T-bird nicely solved the original e-mail oversize problem I had with Microsoft's size limitations and I'd appreciate advice on how to deal with what's happening.

When checking email, Thunderbird's status bar at the bottom will report x number of emails received (e.g., "received 1 of 1 messages"). I have not had difficulty receiving email and those messages displaying in the Inbox--but there have been a number of instances where the status bar will report one or more messages have been received, but none display, despite the fact that I do not nor have I ever had filtering in place. Since I continue to receive emails that display when received, the only thing that concerns me is that there could be messages that are being lost, and I have no idea how to correct the problem and be assured that each and every email is retrieved and displayed. Thank you for your assistance.
