Hi, I've been using Thunderbird latest version for a few days. Too much I have a problem that is bothering me. I have 20 accounts and if I choose Unified Folders, on the six of Tunderbird I see only a part of the Accounts and precisely 14. To solve my problem I also used the "Unified Folder Debugging" add-on but it didn't solve the problem. Why do I have this problem? I would like to use Unified Folders but I can't do it because I don't have any Accounts. Thanks for some info.

Trying to setup Thunderbird for wife’s new laptop… Her 4 separate email accounts with auto setup for the IMAP server info without issues. One account however will not – VERY frustrating as this works fine on her old laptop. Thunderbird setup now appears to have an extra (4th) field required when setting up the account: Usually, its just name, email address and password. I see there’s now an extra box titled ‘Your Login’ being required for auto login. I have no idea what this field should be set to. Also, when I attempt to do a manual setup for the account, the port numbers and server names shown on the internet are completely different to those used on auto, and still get rejected. Doesn’t help that MS trying (and succeeding) to confuse us with all this “Outlook vs Outlook Classic vs Outlook.com”. My wife is unable to continue her work until I get this sorted:-( PLEEEAAASE can someone help me setup this xxxxxxx@outlook.com email account in Thunderbird as an IMAP account?

I always get: "newmsg Trojan:WIN/SuspiciousAttachmentScript.a" and "C:\Users\newb\AppData\Local\Temp Trojan:WIN/SuspiciousAttachmentScript.a" from Mcafee when I open Thunderbird. I'm only getting this in Thunderbird and suspect it's a false positive of some kind. It's still worrying and I'd like to eliminate this. This has been going on for a couple of months. I've run several cleaners and anti-virus programs on the system, but it still returns.

thanks

I have remote content blocked as a default. If I choose to view remote content **for an individual message**, there seems to be no way to reblock it, because the yellow bar with "options" disappears after you allow the remote content for that message. (Whoopsy! Changed my mind! Let's say I don't want the remote content to transmit that I opened the message a second time when I do so.)

Mail Content > Exceptions does not help in this case, since I allowed the remote content from a specific message, rather than allowing a wider permission, such as allowing remote content from a particular email address or website. Copying the message link into Mail Content > Exceptions (as suggested in an old post) doesn't work, either.

So it seems I am now stuck having remote content active each time I need to open that message?

Windows 11 Thunderbird = current at the time of this writing. (150.0.2 64bit)

I want to use thunderbird on a Windows 11 laptop. Tell me how to connect Thunderbird to send and receive emails from email account, jds@sefcik.net, hosted at smartmail.buz.net.

I have 3 different hotmail accounts. And tried to set them up in a newly installed thunderbird app on windows (10,sorry not up to date). In the beginning I had 2 out of 3 working, but the last one is my business account and it didn't connect. I tried many different ways to get it working, and now only the 1st one is still connecting correctly. The second one also doesn't connect anymore and is giving me the: "The connection was refused when attempting to contact localhost." or Authentication error: Unable to log in at server. Probably wrong configuration, username or password.

I know for sure password and username are correct. I have added thunderbird to exceptions in firewall. I also tried turning the firewall off. no changes. I have no idea where it got so messy but can someone guide me in this? Most of it I do not understand so it is obvious I made mistakes.

After updating Thunderbird to version 150.0.2, I can no longer connect to my lolipop.jp mail servers.

Symptoms:

• Both IMAP and SMTP stopped working at the same time
• Webmail works normally
• Multiple mail accounts are affected
• Thunderbird times out when connecting to the servers
• The issue started immediately after updating to Thunderbird 150.0.2

Settings tested:

• IMAP: imap.lolipop.jp / Port 993 / SSL-TLS / Normal password
• SMTP: smtp.lolipop.jp / Port 465 SSL-TLS and Port 587 STARTTLS
• Tried Thunderbird Safe Mode
• Tried reinstalling Thunderbird
• Tried disabling Norton security/firewall temporarily
• Same issue persists

Could this be a known issue with Thunderbird 150.0.2? If so, is there any workaround or planned fix?

Thank you.

I just replaced my WiFi router and was able to get 5 messages after new network set up, but now it can't connect to outgoing or incoming mail server.. I double checked all my setting with Spectrum and all looks good, but won't connect.

I want to change the default download protocol accessing the mail server from imap to pop3. I went into the account settings & changed the default selection from imap to pop3. But the change does not take effect. Tbird still accesses the server using the imap protocol.

I have deleted an email account, then I made sure that the saved password and any traces of the account are gone, but every time I launch the program a window pops up with this message:

Authentication Required - Mozilla Thunderbird https://ha1012.raiolanetworks.es is requesting your username and password. (and the account I had before deleting it)

How can I stop that window from appearing again?

Thanks!

I have filled in an un-correct password a number of times due to incorrect language setting of my keyboard. Then the popup window for this disappeared, and I cannot find a place to enter password. What can I do? It is the password for outgoing email.

I have been using T-bird for years successfully until lately. We have multiple email addresses in Comcast and Gmail, but lately our passwords that we have been using and know are correct because they are written on paper and Keypass, are being changed somehow so that they will no longer work. When we look at the saved passwords in Thunderbird we see some have been changed on a certain date that we did not do, and the password listed now must be about 200 characters long. Then when we go to change the password, it may be listed as changed. Then when we try to send a message with that email address, we get an error message saying, for example, smtp.googlemail.com and a wrong username/address completely. I can find no way to correct the username email in any settings in Thunderbird. I have searched the Thunderbird HELP files many times, but am unable to find any of this addressed anywhere. After trying to fix these problems for most of 3 days now, I have get rid of Thunderbird for an email client that works correctly!!!

I had TB on my desktop for years and finally got it also synced to my phone. Then with a failure with Windows 11 had to wipe clean the desktop and start over. Cannot reinstall TB. I obviously have the correct e-mail and password as I was able to log into Mozilla and submit this question. I believe it is a problem with my user name and what is on my phone setup does not work with my desktop reinstallation.

I am running Windows 11 Pro 25H2. After updating Thunderbird recently to the latest version, it is crashing immediately upon starting Thunderbird, not even bringing up the initial screen.

The message is

"Thunderbird has stopped working. A problem caused the program to stop working correctly. Please close the program."

In addition, it brings up the Mozilla Crash Reporter, which states

"We are sorry

Thunderbird had a problem and crashed. We will try to restore your tabs and windows when it restarts."

I do not want to lose all my old POP3 messages, etc.

Please help, Nina

Hi - I can't seem to delete from my Yahoo Mail via Thunderbird.

With Yahoo's new mailbox limits I wanted to clean up my Yahoo mail box and Yahoo obviously does not provide any decent tools to support search and delete.

I downloaded Thunderbird and despite several deletion attempts my Yahoo mailbox still shows 160,000 emails whilst my Thunderbird client only 9,000 - so when I delete it is not syncing.

Most emails are deleted from Thunderbird however some are now reappearing (in Thunderbird). No deletions from Thunderbird are reachign my Yahoo mail inbox, however I can send emails from Thunderbird and see the sent and received email in Yahoo and I can add folders in Thunderbird and see those folders in Yahoo.

I tried several things

- immeadiate delete in Thunderbird - moving the emails to a folder in Thunderbird and then deleting from that and then deleting the the folder - I check this article https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo and everything appears correct

I've had to pay for extra storage to get the code to make this post.

Hello,

Despite the fact that I have set Thunderbird to display messages as plain text, my needs are not being fully respected. If the message contains some form of markup, presumably HTML, the font size is not what I have chosen. Generally, the font size is smaller than what I have specified in the Thunderbird settings.

This is unacceptable. It is a usability / accessibility issue. If the user chooses Plain Text and sets a font size, they have done that for a reason. Which is accessibility. If Thunderbird ignores the needs of users and applies styling rules to messages, that is a failure state.

Is there some way to actually, truly, absolutely display all messages as plain text in a specified font, weight, and size? If not, what is the protocol for reaching developers so that they can respond to this issue?

Thank you

Is it possible to set up a TLS client certificate for authentication with SMTP, as it is with IMAP?

It works fine on the K-9 Android client for both IMAP and SMTP.

Is there a reason why this hasn't yet been added as an authentication method for SMTP?

Thank you!

Best Regards
