Starting on 10/01/2024 Thunderbird no longer allows me to send or receive email.

When I try to read messages using Thunderbird, I get the following: Sending of password for user XX@msn.com did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password.

When I try to send messages using Thunderbird, I get the following: Enter your password for XX on smtp.office365.com:

I have tried redoing the password and it does not help.

This is on a WIN/10 system. I updated to the latest version of Thunderbird and it did not help.

I checked out Thunderbird on my WIN/XP and get the same results as with WIN/10.

When I use Firefox and login to https://outlook.live.com/mail/0/, I can send and receive email as before. The same is also true with my Mobile Phone.

Hi, I am running Nebula 128.3.0esr and I am unable to send from hotmail. When I go into the outgoing server settings I do not have an option for OATH2 which it requires the other settings are all as per microsofts instructions: SMTP server name: smtp-mail.outlook.com SMTP port: 587 SMTP encryption: STARTTLS I suspect I am doing something stupid but all my other mailboxes are working fine.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

No changes been made to my Mozilla account unless Mozilla banned me for constructive criticism yesterday. Earlier today Oct 4, 24 booted up laptop no issues. 3 hours later from cold start issue.

My version of FF 131.0 updated yesterday indicates I'm not signed in. Repeated sign-in attempts successful only to be disconnected seconds later. No issues logging into Mozilla Monitor to see progress and navigate around without disconnection. On Android 11 cell phone no issues, on Asus tablet Android 7.0 no issues. What am I doing wrong or missing? See attached screen shots and browser data.

Thank you in advance for your assistance.

I use Thunderbird Mail, I have two email accounts, a gmail and an icloud. Now a problem has occurred, all subfolders for icloud have disappeared from Thunderbird. I had different folders of saved correspondence, but now I just see Inbox, Archive and thrash. Anyone know what I can do to get those folders back, for gmail account everything is ok

I have received several emails on my laptop Tunderbird account with content like this:

I can read these emails using BlueMail on my phone. Can you assist in resolving this issue please? Thank you

What will wiggers do at the end? I of it all because that day is coming, be ready stay steady hope your hand is heavy if it's not then there'll be snot and you'll look Petty

I have Thunderbird 102.15.1. I can receive emails from my Hotmail account (set up as POP3), and up until 22/09/2024 I could also send emails through Hotmail.

At some point after 22/09/2024 I am no longer able to send emails through Hotmail.

I have the following setting for the outgoing server (SMTP) (which worked fine until 22/09/2024):

Description: hotmail server name: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: Normal password

When I try to send an email I get the following message:

 "Enter your password for adriharp@hotmail.com on smtp.office365.com:"

with the password dialog box underneath.

If I change the authentication method to OAUTH2 for the outgoing SMTP server, I very briefly see the "enter credentials" screen flash up, then the Sending message box appears and Thunderbird hangs until I hit the Cancel button. If I leave it to run, I get this message:

 "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again."

If I try to generate a new app password in my Microsoft account and enter this with the outgoing SMTP server authentication set to Normal Password, I get this message:

 "Login to server smtp.office365.com with username adriharp@hotmail.com failed."

I use OAUTH2 authentication for the incoming Hotmail server (SSL/TLS on outlook.office365.com). This works fine.

My questions are: - does anyone know why this change happened in the last few weeks ? - how can I change my settings in Thunderbird (and/or Microsoft Hotmail a/c) to send emails via my Hotmail account ? - do I need to upgrade Thunderbird to send emails via my Hotmail account ?

I am running Windows 7 on this laptop so I think my options to upgrade are limited to 115.10.01.

Thanks for your help.

I have installed T'bird in a new replacement pc and also added my two accounts. However, I now need to include my many Local Folders using Profile Folder information from the old pc.

Should I delete all the account information I have installed in my new pc T'bird prior to installing the Profile Folder copy? Thanks Ron
