One of my email accounts will not connect. It was working but has not connected for two days. The message says log in failed for X@yahoo.com.

ever since last update... can't send emails

Send Message Error Sending of the message failed. An error occurred while sending mail. The mail server responded: E5rTxqhwZYbiPE5rUxBTZm DMARC Policy Enforcement: https://postmaster.comcast.net/smtp-error-codes.php#ODM00001. Please check the message and try again.

1. Some messages come to my mobile devices but not to my Mac. 2. I watch a message down load but it doesn't end up in my inbox or junk folder. 3. Junk folder says there are 14 messages in it, but when I open it, it's empty. 4. Yes, I'm up to date with Thunderbird. Also, the Mac is up to date. Problem began before latest updates. I have shut down the Mac. I have quit the Thunderbird application. No improvement. 5. I use Comcast for my ISP.

When I send a message the send box does not close. It remains open and says it is saving the message in the sent folder. I then have to quit thunderbird in order to close the box and get back to using thunderbird again. It does save it in the sent folder. but the box remains open Why is it doing this?

Thunder bird version 140.10.Oesr on iMac desktop. Just stopped DL mail. Asked me to sign in; shows my user name. When I click NEXT it goes to a blank page and say "too many trys" Next dy; say on first attmpt.

I hope you all are well!

I´ve been having a problem with thunderbird for a while now and today took the time to do the troubleshoot and checked all the account settings. no firewall, no add ons Researching the problem i came across the incompability of different TLS standards. Apparently when thunderbird updated to 78.0 in 2020 a lot of people had the same problem and solved it by downgrading . Since this problem came on suddenly, possibly when thunderbird upgraded automatically, and it only applys to select emails (about half) I guess different TLS standards, some of which are no longer supported by thunderbird, are the reason for this. If i log in to my mailaccount I can see all the emails, same goes for my mobile devices. That´s how i know thunderbird doesn´t display all the messages. My question: Did anyone else encounter this problem? Did I analize this correctly or did I overlook something? I don´t want to change to another provider. I always liked thunderbird for being simple and clean. But downgrading won´t be a sustainable solution either I guess. Thanx for your help. Have a nice day.

For the last 2 days or so, I cannot receive emails in Thunderbird from my Comcast email account, The app receives from other accounts. The app also sends emails from all my accounts, lets me read already-received messages and move the messages to other folders as it usually does. I just can't receive emails from Comcast/Xfinity. I note that Thunderbird had a update a few days ago.

When I send an email, a window pops up that shows the sending progress. Emails appear to send and save to the sent folder just fine, but the window doesn't close and will remain open until I press the cancel button. Is it possible to fix this?

My computer has not worked for nine months.

I've been looking at my e-mail on my phone (not in Thunderbird for Android, which pretended to send my messages but didn't). I want it on my computer.

I didn't want to do that right away, but it looks like Thunderbird started doing that automatically when I launched it. It successfully got my small account, of course, but not my big one.

It's been stuck on this for more than 12 hours. (See image. My apologies, I've forgotten how to embed them.)

Is it safe to shut the process down? Whether it is or isn't, what do I do next?

My computer is a MacBook Pro (13-inch, Mid 2012), running OS X.15 (Catalina), with Thunderbird 140.0.1esr (64-bit). The process started before I could upgrade to 149esr.

Thank you for any help you can give me!

UPDATE, 4/11, 8PM EDT: No change. . . .

I can no longer get email from my Yahoo email account. I've gone through all the troubleshooting hints and recommendations, as I understand them, but without any luck.

I only have the one account.

The Activity Manager (see attached) shows "No messages to download", but the message at the bottom left said there were messages, but TB doesn't download them.

When I try to send an email using my Mozilla account, the only choice provided is "send later". I do not want and did not knowingly ask for the choice "send later". How can I have my emails sent right away? Thank you very very much for any help you can give me.
