Thunderbird Support Forum

I would like to change my account settings for my hotmail account, but when I try to change from Normal Password under Outgoing Server (SMTP) there is no option for Oauth. Is there something I can do to enable this option.

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !

My Thunderbird Version: 115.12.2 (32 Bit)

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide here,

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

And I get to this screen - but my version of the program does not have OAuth2 as an option (see attached image).

Thanks for the help.

I am running version 115.12.2 (64-bit). I have deleted all stored passwords using Settings -> Privacy and Security -> Show Passwords. As expected, when I try to retrieve emails a pop-up appears asking for the password - which I save. However, when I try to send an email there is no pop-up and the remote server rejects the email. How do I set a new outgoing password?

Hello,

When the primary password window opens and I click Cancel, can that window close AND can it prevent Thunderbird from opening?

Example: what if I bring my pc to a repair shop and they open thunderbird and click Cancel on the primary password window. They can See my previously viewed email. I do not want them to see those. Clicking Cancel AND closing Thunderbird would prevent them from seeing emails.

Could this be a future enhancement?

Thanks

Hello,

So - SMTP suddenly stopped working in our whole company. We are using Gmail accounts configured with Thunderbird for a few years already. It's all been working until an hour ago.

Tried deleting and adding accounts, changing authentification to google app passwords etc.\

SMTP servers do have different descriptions.

Just configured an account in outlook and it works out of the box, so I'm guessing it's got something to do with Thunderbird settings, but we didn't change anything, and especially that we have 8 PCs and it stopped working on every one of it.

The error I get when trying to send a message is:

"Sending message failed. The message failed to send because it failed to connect to the outgoing mail (SMTP) server "smtp.gmail.com". The server may be unreachable or not accepting SMTP connections. Please verify that your outgoing mail server settings are correct and then try again or contact your server administrator."

(translated from polish).

Best regards.

Without notice, Thunderbird today required me to sign-in to my Google account and then produced a window in which it said it wanted to access to my mail, contacts and calendar; in order to compose, send, share, delete permanently, among actions on my personal content. I tried to "Deny" (see below) but the window just returned and returned and could not be deleted. (see "Uploaded images", below for the content of this window).

Is this a scam? Or the result of a hacker?

Lately I have been getting a lot of spam and have identified all coming into my inbox as spam. Now many are automatically moved to junk mail box and that is a good thing. Unfortunately it also seems to be slowing Thunderbird down. I am afraid that many of the "Filters" generated may be duplicated. Is it possible to see them and maybe edit them to reduce the impact on my system?

I've used Thunderbird for years using a POP setting; Network Solutions would prefer that I use IMAP. I don't know the difference, but they must and prefer that it be IMAP (netsol-imap-oxcs.hostingplatform.com) (PORT: 993. When bringing up the settings in my mail account, it doesn't allow anyone to change that field. What can I do? I want to use Thunderbird; because of this particular setting I haven't been able to, and must instead log on to Network Solutions and go through their email interface. Thank you.

I've appreciated using Thunderbird for an ad-free Hotmail experience for quite some time. I've changed my Hotmail password every few weeks lately and Thunderbird worked fine when I entered the new password at the prompt when Thunderbird started.

Just now however, I needed to get into my Microsoft account that uses the same password as my Hotmail account. My login to Microsoft failed. Trying to understand why, I looked in Thunderbird at the saved password for Hotmail's server:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All

https://outlook.office.com/POP.AccessAsUser.All 
https://outlook.office.com/SMTP.Send offline_access)

The saved password was a 464 character long ASCII string totally irrelevant to the password I'd selected for Hotmail and Microsoft.

I went through the password change process for Hotmail, was then able to get into my Microsoft account and restarted Thunderbird. As usual, Thunderbird asked for the new password. I entered it and was then able to receive new mail from the Hotmail server in Thunderbird. However, again, the saved password in Thunderbird for Hotmail was not the password I'd entered.

Next, I deleted the saved passwords in Thunderbird, restarted it and this time it prompted me to be sure I'd downloaded it from a reliable source. I've never seen that prompt before. It came with my Linux Mint installation, so I thought it would be safe, but again there's an irrelevant password saved for my Hotmail account.

It's like it eventually changes my password for Hotmail and Microsoft since I can get mail through Thunderbird with the odd password it saves, but if I use what should be my password for Hotmail or my Microsoft account via a web page interface, the password doesn't work.

I'll have to stop using Thunderbird if this continues.

Dear Sir/Madam,

I use the Thunderbird email client on my Microsoft Windows 10 desktop tower PC in order to access my Gmail account using POP3, using "only" my email address and password.

However, I note that Google plan to introduce more stringent and tighter sign in/authentication methods from September 2024 as follows:

https://support.google.com/a/answer/6260879?hl=en

https://support.google.com/a/answer/6260879?hl=en

Does Thunderbird have a workaround for Google's plans please?

Thanking you.

Hi

I cant find an Add-On for blocking ads in newsletters.

How can I block the very annoying Ads in newsletters? These newsletters from mainstream newspapers are a real imposition.

How-To block ads in mails with Thunderbird?

I have had a client for whom I use an outlook.office365.com "thing" and get/send e-mails through their domain.

In prior Tbird releases it just accepted whatever credentials Tbird presents

Recent release - I still authenticate just fine - can receive and transmit e-mails without issue. But every couple of minutes I get a nag screen asking me to login to login.live.com. I dismiss the nag screen, and can still transmit and receive e-mails. This screen is initiated by a Thunderbird process (I know this because if I kill a Thunderbird process in task manager, the screen goes away and everything works as expected. )

I really want no part of the Windows "Live" thing, and have no idea of what "helpful" changes it wants to make, and so I do not login.

"Settings" are set up with cookies set to yes. OAuth2 seems to be selected.

I see no settings that I could use to suppress the nag ... is there anything I can do???

Thanks in advance.

Hello: I can't seem to receive emails from a specific address from a professional office (with their own URL), which I have never (not knowingly) ever classified as JUNK, ... I have checked my Junk box, Deleted Box, and my filters from __@Bell.net, from which I download to T-Bird. That email addr or URL is NOT blocked, and I have put that addr on my "SafeSenders" List.

I don't see that email anywhere else in T-Bird Folders,, and the sender had to call me, and resend from a diff address, their own Gmail acct.!

And I can send to them, to few ppl in that office,... And I don't get any emails from anyone @the URL, meaning no other staff from that URL can send anything to me!

Did I accidentally classify it as JUNK, but I never received anything from the beginning,.. So I do NOT believe I would have set it as Junk...

I have checked ALL settings in T-Bird and at __Bell.Net in my settings, but to no avail.

Pls help, Much appreciated, Az

I went to passwords to change my password and one of the email ids - bobmater@comcast.net - is missing. There’s no account listed to change the password. All my other emails addresses are there. I think when you changed over, you deleted my account somehow.

A while ago my long-time hotmail account stopped working on two computer with windows 10 and one with windows 11. Last night, I looked up an article that said I have to use Oauth2 instead of normal pw. I made that change on the windows 11 machine and a popup occurred that wanted the number from the google authenticator on my phone. I gave it that and it checks mail now just fine.

This morning I went to one of the Windows 10 machines and did exactly the same. I tried some different server names online and tried some, but after a while I started getting a little window that asked my email address and pw. I put my hotmail address in and got this message:

Microsoft Accounts or personal email addresses don’t work here. Make sure you enter your work or school account (e.g. user@contoso.com). If you want to reset a Microsoft Account password, click here.

Now this is the very same hotmail email that worked on windows 11 with the same server settings last night. It still works.

Now, on the windows 10 machine with those same settings, I get the blank extra window. The extra window appears, does not populate, and disappeared.

It is: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=redacted@hotmail.com

I had no opportunity to do what worked on the windows 11 machine just last night. I cannot check mail on hotmail on this windows 10 pc. I took all the updates available to Thunderbird and firefox. TB is 115.11.1

I'm stopped. Why would it work on one pc and not another? Oauth2 on the windows 11 asked for authenticator. On the windows 10 it never asks.

I have a problem with Thunderbird 115.11.1 with the POP3 server inbound.att.net. Someone on at at7t forum suggested changing from Userid/password to Secure Mail Key. I had previously set up two Keys with at&t, but AI have never activated them. I looked at one URL, and was able to change the settings for inbound.att.net. But I did not see anywhere to enter one of the Keys that I had generated earlier. When I tried to re-configure outbound.att.net, I did not see a OAuth2 option. I do not need to re-configure outbound at the present time, as I can send mail without a problem. But receiving mail does not work. Here is what I see in the error console log:

Here is what I changed: Thunderbird: Account Settings --> Server Setings --> Security Settings --> Authentication Method Normal Pasword -> OAuth2

                                                   Inbound.att.net: Port 995 --> 587
                                                   Connection Security: SSL/TLS --> STARTTLS 
   

What do I have to do to get one of my two Keys into the inbound Thunderbird configuration? Thanks.
