Thunderbird Support Forum

I'm setting up a new PC, and am using the same settings that have been on the old PC for three years and are in the Yahoo configuration guide: Pop3 inbound. att.net/outbound. att.net 995/465 SSL/TLS Normal Password

I've been at this for hours, and Tbird just won't connect. The error is "Unable to log in at server. Probably wrong configuration, username or password". I am stumped.

I temporarily logged into customer email account in order to download the mail in it and transfer it to their email at a different webhost.

And in fact subsequent to that the email account was closed at the prior host by its owner. They actually deleted the email account at the old host "Bluehost" which admittedly is a garbage host and hence why they moved.

So I removed it from my email accounts in my Thunderbird.

For some reason since then I have been receiving constant popups from Thunderbird "Authentication Required - Mozilla Thunderbird - https://box2164.bluehost.com:2080 is requesting your username and password. The site says: “Horde DAV Server”"

and the username field has the email address in it. The password field is blank.

And I checked the outgoing mail servers in Thunderbird to confirm I have no connection to the email acct stored in Thunderbird.

Any thoughts on how to alleviate this issue?

Thank you all for your time and attention to this request.

I used to send a group from my address book with 15 addresses in it.

Now I get this message "Sending of the message failed. An error occurred while sending mail. The mail server responded: mL0anej4od7RfmL0bnCIXh internal error. AUP#SMTP. Please check the message recipient "kissrockssoo@shaw.ca" and try again."

I broke the group into two groups one with 8 and one with seven. I can send to each group individually so I do not understand why the larger group won't go.

Were limits put on at your end?

Hi everyone,

My costumer has a problem with Thundebird. She has a email address with Aruba Business, after 3-4 days Thunderbird change email settings and email address with an address never existed, i leave attached some screenshots. In this PC i restore and reinstalled Windows 10 to avoid this problem, but after 3 days after reinstallation the problem returns.

Thanks and have a good day.

Getting XUL Runner error message: Version ‘91.8.0’ is not compatible with MinVersion >= 91.9.0 MaxVersion <= 91.9.0

Will not open Thunderbird email at all. Please assist…

My ISP (GoDaddy) recently switched my email account to Outlook. I made some resettings on Thunderbird and now am able to receive my emails there again, but cannot send them out. GoDaddy has sent me the appropriate settings, but no matter what I try to toggle with those, I get an error message. Still receiving emails, though, with no problems.

The error message below continues to be happening with the Social Security Dept. that never happened before. I have called hostgator many times and they said to write Mozilla to correct this problem. Please help!!!!!!

A specific set of 57 emails from the time period 3/1 to 3/2 keeps coming back into my Inbox after deleting them or moving them to another folder. Any suggestions as to how to fix this problem? Thanks.

Hello,

I don't know what has changed, but Thunderbird deleted older e-mails from both my and my daughter's Inboxes! The messages had not been starred, but they were important and thus saved in special folders (such as TRAVEL CONFIRMATIONS and COLLEGE INFO). Their disappearance has been highly problematic, distressing, frustrating!

Does anyone know WHY this happened and how to FIX/PREVENT it?

We Tried the following fix, but we don't know if this is correct: > [Clicked] Triple Bar > Account Settings > Synchronization & Storage > Disk Space > [Checked] Don't Delete Any Messages > [Checked] Don't Delete Starred Messages.

Incidentally, we saw the the box "Delete Messages Older than 45 days" was Checked, but neither of us had done that! Is this a Default? If so, IT MUST GO! (I had foreign travel confirmations that were ONLY in Inbox and couldn't be confirmed any other way.)

Thank you!

No error message to report. When I search in folders, I can preview the contents of a given message. This is working fine every place except one of my Trash folders. I have three main folders, each of which has a Trash folder within it. Periodically I move all messages from two of those folders to my main Trash folder.

Previewing messages works in all of my folders, including all of the Trash folders EXCEPT for the most important Trash folder. There, every message is displaying alright UNTIL I enter something in the Quick Filter. As soon as I do that, all messages in the folder display blank contents.

Once that happens, even clearing the Quick Filter doesn't return message contents.

Gents, I've been using Thunderbird since years without main problems; today I removed from "saved password" one of my accounts; thereafter TB crashed and now is repeatedly crashing immediately after startup; I tried in safe mode but with identical result. Someone could help in restoring?

I have never seen anything like this. I went to open TB from the taskbar and the only way I can see it is a tiny thumbnail in the upper left corner of my monitor and no way to enlarge it. I closed and reopened several times , no joy. I restarted my desktop, no joy. I managed to arrow to the right from file and got to help. chose the update message. restarted but still same way. If I uninstall it will I lose everything? I was planning to migrate it to my laptop but only going to be home 1 day and afraid to try it. I could use it on Webmail for my trip but I wouldn't have my address book or all of my file folders. H E L P Please.

Ubuntu: 20.04 LTS Kernel: 5.13.0-40-generic Thunderbird: 91.7.0 (64 bit)

Since starting service with an new ISP, I have been having problems with Thunderbird outgoing mail (incoming works fine). I did not see this problem with my previous ISP.

In both plain text and HTML formats, if the body of the email is greater than approx. 930 characters, when I click <Send>, the progress window goes to 100% sent, then hangs and eventually times out with the message not being sent. It shows an error message:

"Sending of message failed The message could not be sent usin Outgoing server for an unknown reason. Pleas verify that your Outgoing server settings are correct and try again."

I have contacted the new ISP about this and they have no idea what is causing this except it is not a problem with their SMTP host. All email settings are as directed by the new ISP.

I have confirmed this on 2 computers, both running the same software by creating messages with known character counts of over 1000 characters, created in a basic text editor, and progressively deleting characters until it is successfully sent and recounting the characters.

EDIT: After reinstalling Windows 10 and Thunderbird, I attempted so send an email with a 78Kb attachment, which failed with the message:

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.seaside.ns.ca was lost in the middle of the transaction. Try again.

Further searching on the Web has led me to looking at an old thread:

https://thunderbirdtweaks.blogspot.com/2010/10/i-cant-sent-mail-networktcpsendbuffer.html

but this had no effect.

I am at a loss, so any possible clues as to what is going on would be greatly appreciated.

All of a sudden when I try to print my emails from my MacBook Air, they come out all garbled like HTML code. Headers and body copy all come out in code instead of formatted correctly. I've tried everything I can think of to try to correct this issue, but I'm out of ideas. It works perfectly fine from both my other desktop computers. It's just happening with my laptop. I NEED to be able to print my emails from my laptop so I have GOT to get this figured out. Please help!

About Release Versions

On T-Bird I receive an email which contains links. Normally these activate and transfer to the link site when clicked. This no longer works!

This is a pain in the proverbial.

Also with your celebrated Firefox 100 - the links in text don't work either when clicked I have to copy the links and paste to the url box to move to the link site.

Look every thing was working fine 3 days ago - I have done absolutely nothing to my laptop.

I think Mozilla reliability is simply getting worse .

When things are working well - you need more checking before an upgrade .

I was on Beta release last year - my experience with beta was dreadful - cost me 1.5 months of work.

I want to go back to the previous Release version of Firefox and T-bird - how to do this easily.

I am going to shutdown automatic updating as you cannot get things right it seems.

I am a former Netscape user

I've been experiencing major Thunderbird freezes, which seem to coincide with the 91.8.1 release. I've gone as far as a complete reinstall of both Mint 20.3 and Thunderbird, and the problem persists.

Steps to reproduce: Compose and attempt to send a message.

Result: Thunderbird shows the 'sending message' dialog box, and stops. This will result in anything from a freeze that can sometimes be recovered from by force quitting (but only after several minutes, and I can't drop to a terminal to kill the process), to a complete system freeze that disables the power button, requiring removal of the laptop battery and disconnecting the charger. The freeze occurs using any of four email accounts that worked perfectly prior to introduction of the problem.

The only fix I've found so far is to disable hardware acceleration. After doing this, I've been able to send a dozen or so test messages so far.

Is this a known issue? I haven't seen a similar report, but I can't believe mine is the only machine affected.

Several times, if I receive images larger than 3 mb, thunderbird cannot open the mail. It starts consuming all the memory, but I can't open the mail. It consumes 32GB of ram. I tried to update, but the latest version is up. 91.9.0. 64 bits. I tried turning on compression, but it still freezes. What should I do?
