Yahoo has made changes recently, supposedly in the name of security, that have had quite the opposite effect for those of us who use Thunderbird for email on shared computers. Before Yahoo's recent changes, Thunderbird would ask users to enter their password before connecting to the email server. This is no longer the case. Now, when logging into Thunderbird, there is no dialog box popping up for entering a password, Thunderbird just automatically connects. This needs to be corrected. Hopefully someone at Mozilla is listening and will take action.

So far, the only work-around I have found has been to go into Account Settings, Thuderbird Preferences, Saved Passwords, and deleting the oauth password that was automatically saved when I jumped through Yahoo's hoops to get my email working again after they implemented their recent changes. This has to be done EACH SESSION and, if this is done, then the next time I want to get my email I have to repeat the process of generating a new oauth token by logging into Yahoo by way of my browser, which will then be saved once again in Thunderbird and will, once again, need to be deleted at the end of the session. This is obviously a colossal PITA.

Someone PLEASE FIX THIS!

I just started having issues with Thunderbird. When I open it I'm getting the error: Login to server imap-mail.outlook.com with username has failed. I've tried entering my password, no luck. Changed my password and can open my hotmail account in outlook so I know the new password is right, but still no luck in Thunderbird. After too many Retry attempts I get an error in the bottom corner that says something like: the server is offline or may be disconnected (disappears too quick to catch it).

Thoughts on how to resolve?

Thanks, Kevin

Hi, Thunderbird was working fine in the morning, but later in the day, it suddenly stopped downloading messages from my Hotmail inbox and asked for my password again. When I entered my password, I got the following error message:

"Sending of password for user mazyarm@hotmail.com did not succeed. Mail server pop-mail.outlook.com responded: Authentication failure: unknown user name or bad password."

Thunderbird won't sign in to check emails. I also get the message:

"Login to server pop-mail.outlook.com with username mazyarm@hotmail.com failed."

And those are the messages I now get whenever I click on the Get Messages button. However, I am still able to access my Hotmail account directly using the Firefox web browser, so I know that my username and password are not the problem.

Does anyone know what's going on? How do I solve this problem? Thank you, Maz

I have Thunderbird 128.2.3 (32 bit). I have set Server type IMAP mail server, then Server Name to: outlook.office365.com and Outgoing Server: smtp.office365.com I have OAuth2 on both. When I enter, I get a new Thunderbird input that requires a password. My password does not work, the therefore my email account does not work.

I have confirmed that my Outlook Password is correct. I have cancelled my Outlook passwords. I have installed the 2 step verification option.

What needs to be done so I can use Thunderbird on my PC Win 10? Thank you, Ed

Whenever I sign in to sync my browser it keeps asking me to sign in again to reconnect to sync.

I've tried reinstalling the browser, deleting the Mozilla directory in %APPDATA% and reinstalling, removing account and signing in again.

No matter what I do I keep getting asked to sign in again to reconnect even though the initial sign in was successful.

I DON'T want my email account password to be saved anywhere in Thunderbird and I DO want to have to enter the password each time I start up Thunderbird anew. However, my password is being retained. I've deleted the password entry from Settings & Saved Passwords but seem to have to do that every time before I close down. Where/how can I ensure I have to enter my hotmail password each time I start up Thunderbird please?

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.

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.

I have three email accounts in Thunderbird on my Windows 10 PC which are all with Yahoo. The accounts are ex Sky accounts but are now run by Yahoo.

I am replacing that PC with a Windows 11 laptop so I need to migrate.

I exported the Thunderbird data using the export tool and when I imported the file into the new Thunderbird installation on the laptop I got three pop up messages from yahoo asking me to agree to allow access but they all related to the first of the accounts. I can send and receive from the first account but can neither send or receive from the other two accounts.

I have tried deleting the last two accounts and adding them manually but the yahoo pop up again refers to the first account.

Any suggestions?

I Menu app icon > Help > More Troubleshooting Information

   Under 'Application Basics' - Profile Folder - click on 'Open Folder' 

This opens a new window showing the contents of your current in use profile name folder.

   Exit Thunderbird now - this is important. 

Look for the following files and delete them.

   cert8.db - obselete file
   cert9.db - currently used file
   key3.db - obselete file
   key4.db - current used file
   logins.json - current used file
   pkcs11.txt (some people report this file missing)
   secmod.db - obselete file
   session.json
   xulstore.json 

See next comment before you start Thunderbird as you need to empty cache files.

Start Thunderbird

Add yahoo and make sure all the settings are correct. Make sure Authentication Method is Oauth and user name is full yahoo email address.

Report on results.

ADDITIONAL Whilst Thunderbird is closed - after you have deleted the files mentioned previously.

access : C:/Users/ User Account/Appdata/Local/Thunderbird/Profiles/ Please note this is the Appdata 'Local' location which the computer uses as a cache. Be sure you are in the 'Local' and not the 'Roaming' Delete the contents of the 'Profiles' folder.

then start Thunderbird. keep having to reset my secure key password and tried this in "Roaming" instead of "Local" Help!

I use SMTP settings

Description: smtp.office365.com Server Name: smtp.office365.com Port: 587 User Name: mypersonalaccout@hotmail.com Authentication method: OAuth2 Connection Security: STARTTLS

but TB is incapable of sending email. Either I got dialog https://software9119.technology/__other/tb/dialog.png or error https://software9119.technology/__other/tb/timed-out.png.

I tried cleaning cache and made some re+/search with no avail. There seems to exist some Authenticated SMTP but this is only available on Exchange 365 while this is my personal Outlook.com account.

Good afternoon,

I have read in an article a statement that Primary Password encrypts all saved logins, therefore it is safer and recommended to use it. Well, I observed that it does not really matter if the password is set for the contents of logins.json, it does not change. What exactly is encrypted by Primary Password and how does it improve security?

I also tried to set the same password for different websites (I used a different mail tho) and the output in logins.json is different, which is even more confusing to me.

The output itself is kind of strange, the first part of it seems to be the same for almost all entries and looks like that: MEoEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwc.

When I try to enter a password for any website after a few updates ago, I don't get the option to enter my password that's saved in my password list into the fields anymore. I have to manually search, copy, and paste the information in. The app will then ask me if I want to update or modify the login information that is unchanged from what should already be in my browser.

Regardless of whether I say yes or no, the password remains unselectable when I go back to that website, and when I manually enter the information, it again asks me if I want to update the login information.

I have been using Thunderbird for quite a few years. Two weeks ago I started getting a message saying : "login to server imap.comcast.net with username ...... failed."

What can I do to get back in? marlindy

The security sequence for log-in is supply of user-id and then password; that works fine; then a send unique code dialogue pops up and it leads to an error screen which I am attaching. I have rung the number provided and they say they don't support Firefox; so that looks like end of Firefox use to me and goodbye (can't find a tearful emoji to insert).

Gotta say this kind of thing is happening quite frequently for me; mostly without a nice error screen like this one; last one I recall was hunting for car insurance; on the screen where it listed the billions of quotes to eager providers none of the links to click through for the quotes worked... and with this happeneing more frequently now you go... ohh it's firefox again isn't it... so you reluctantly fire up Google Chrome and of course it works OK.

So I'm kinda here with a broader outlook than just this specific problem; I really am on the verge of giving up with Firefox; it should just work shouldn't it; and it increasingly doesn't anymore; I don't want to get into an extended and convoluted dialogue to help you cure this issue; I'm simply perplexed that some really basic stuff doesn't work anymore; however; I've used Firefox for centuries so thought I should give you at least a chance so I could declare how I feel etc.

I am up for a dialogue over this and hoping this is an easy fix; but; as I say; I'm confused as to why, for me, Firefox just simply doesn't work well anymore; it just should and I shouldn't be here.

I had Thunderbird set up using the native icloud calendar function, but today it is asking me repeatedly for my caldav icloud ID and password. When I enter the login credentials, they are not being accepted by Thunderbird. I am using my icloud ID and the app specific password I set up for Thunderbird - but they are not being accepted anymore by Thunderbird. How can I get Thunderbird to accept my icloud login credentials, so I can see my calendars?

Hi folks After manyyears of using Sage accounting software, somehow Firefox no longer saves my Sage username, which is very annoying as now every time I login I have to manually type my Sage username. Clearely I have clicked something I shoudn't and I wonder if anyone can help me save the username again? Thx.

When I access Saved Logins (>Tools>Saved Passwords>Show Passwords) the display shows a box "Windows Security" and asks for a Password.

I have never seen this box before when accessing Saved Logins (Show Passwords).

I have not made any changes on my computer that should cause this proglem.

Is there any way to correct this so I can Show Passwords ?

Thanks
