I continually received the following pop up window "Sending of password for user ######@hotmail.com did not succeed. Mail server pop3.live.com responded: Authentication failure: unknown user name or bad password."

How do I fix?

I've created (multiple times) a app password on https://account.live.com/proofs/AppPassword. I let Thunderbird autodetect the servers which seems to work ( (imap) outlook.office365.com:993 and smtp.office365.com:587 )

But the password is rejected. The user interface in Thunderbird is bit unclear what exactly fails. Is there a possibility to see where in the handshake to connection is rejected?

WTF did you guys do? I updated today, and now it's asking for passwords continually, and it's not even showing all the emails. I've entered passwords for each account 3 times already and it won't stop asking.

How do I get the previous version back?

Comcast suggested I change my password, so I did. It worked on my laptop but not here on my PC, I can't access Tbird emails on the PC. It will not recognize my new comcast password. HELP

I'm having trouble with my Thunderbird password. I have 2 emails with identical settings and passwords. One works fine. The other's asking me for my password. When I enter what I knew for certain was the password I get the message, "Login to server imap.comcast.net with username weissfamily@comcast.net failed." I successfully changed the password still get the same error message. Also I get a Thunderbird popup that says, "Alert from account weissfamily@comcast.net: 1014." This is all above my pay grade. Need assistance. TIA. Tim Weiss

Please help! Out of the blue Thunderbird is saying my password failed. I did not do anything at all to make this happen. It has worked fine for years. But now I am unable to get in. I have spent hours trying to change the password and now I am lost in confusion. Nothing is working. I uninstalled and reinstalled Thunderbird. Still cannot get in. What can I do? How do I know when someone answers this? I cannot get email.

I am unable to send emails using my thunderbird account from my OnlineBookClub addresses.

Please verify that your outgoing server settings are correct and try again.

I have a new phone, and I can't get my email on it without the email password. I've had the account so long I can't remember the password; Thunderbird just retrieves my email. Now I want it on the phone. Is there a way to get my password out of thunderbird so I can put it in my phone?

I have to maintain a number of MS Outlook mail accounts. Every day, sometimes more than once per day I have to authorize access to the accounts. What is causing this problem, and how to prevent? Is it a Thunderbird problem or a Microsoft problem? Thanks for your help. Paul

I'm running the latest version of Tbird on a Windows 10 machine. My provider is Comcast. (Xfinity). The program no longer accepts my password and there are no saved passwords in the "Saved Passwords". How can I reset my password? It says no account found. I've been using Tbird for a LONG time.

I can't get emails from Thunderbird. It requires a change of pasword for mail.btinternet.com which I don't use.

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.

Hi

My Thunderbird password has been compromised and I've been trying to create a new password for my email inbox. I've followed all the guides but just can't seem to do this!! My email location does not appear in 'saved passwords' which doesn't seem to be helping...please help!!

I've received a message from Google saying "We’re writing to let you know that starting September 30, 2024, your Gmail, Contact and Calendar account will no longer support less secure apps, third-party apps or devices that ask you to sign in to your Google Account using only your username and password."

Will this have any effect on my Thunderbird usage? Many thanks
