Thunderbird Support Forum

When I try to send emails, I receive this message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: [M1] Authentication required (6aecbed3-07a6-11ef-9de7-83bcbd00a978). Please verify that your email address is correct in your account settings and try again". I have checked as requested by this message, and everything appears to be in order. Can anyone help with this issue, please?

I downloaded Thunderbird from Microsoft store. I enter my name, email and password. The first message was "Configuration found in Mozilla ISP database", but the last message was the Error: "Unable to log in at server. Probably wrong configuration, username or password".

Email is from gmail. App version is 115.9.0 (64-bit).

Cannot send email. Has there been a Thunderbird virus since last update? I conferred with Charter Communications and they were unable locate any problems. However, I did note early on that in settings Charter Communications was spelt incorrectly. (Commuications).

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

Hello, I'm not very computer savvy so don't understand why this is happening or even what a blacklist is. I've attached screenshots. I tried to google what to do but don't understand the complicated things posted. Any help would be greatly appreciated.

I am having difficulty getting certain emails. I am told by the sender that they "bounce back as a spam warning" Sometimes I don't know the emails I am NOT getting until I'm told. Two my daughter tried sending me an email and it took over 24 hours to get and she was getting bounce back messages. I can't get "NextDoor" notifications, a store in London couldn't email me, a local contractor couldn't send me an email, etc.. It's random who can't email me, but it's becoming increasingly concerning. It's only certain, legitimate emails. I still get all the spam! Where should I begin? I'm on Windows 10 Pro, using a yahoo/att email through Thunderbird. thanks for any suggestions! Cindy

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

I have just upgraded to 115.9.0(64-bit). Now when I select "Send to email client" I get a message that either there is no default email client or the current client cannot fulfil the request. This did not happen before the upgrade

My e-mail inbox shows a high gigabyte use-age rate, but I only have a few messages in there. I get my messages a couple of times per day and delete emails I don't want to keep. Now it will not get all my new messages as it saying I have run out of disk space. It seems that messages I delete don't really get deleted?? even though they go to trash and I clean the trash folder. I have tried compacting but that didn't work. It seems to be only on my win 10 laptop, as my XP computer is working fine. I have plenty of disk space left on the hard drive. Thanks in advance Bob Parkman

Seems after the latest update Thunderbird will not receive some emails. It has stopped receiving emails coming from some cell phones and some .com emails. Some cell phone emails work and others that previously did do not anymore. I do not understand the random situation. No settings have been changed nor is there any setting to correct this. I even reinstalled Thunderbird.

Any suggestions would be great. Thanks
