Thunderbird Community Forum

Login to the server pop.gmx.net with username "..." failed.

I have several accounts with GMX. Two work, and the other two display the above error message. Everything works when I log in via a browser, but not in Thunderbird. The account settings are identical for all four accounts except for the password and username.

What can I do?

Thank you in advance.

I used to be able to access filters and set them up, but now I can't even find where they're located to set a new one. I've been through every possible setting, and still can't find the filters. Where are they? They've obviously been moved to somewhere obscure since I last used them (many versions ago, and they still run, I just can't locate them).

Thanks in advance.

PLEASE put the format options back into the email task bar! My formatting needs to be done on a message by message basis. It is time consuming and counterproductive to have to go to settings each time. No matter what I tried in settings, I was not able to get Formatting back into the message task bar. At minimum, I need font, size, list and color options back in the message task bar. PLEASE HELP!

Hello,

I need assistance with a very specific Thunderbird issue.

I use Thunderbird with multiple email accounts. Every one of them has a functioning Junk/Spam folder except for one: my Google Workspace account max@dantanas.com

. This is the only account where Thunderbird refuses to create or recognize a Junk/Spam folder, and the option to assign one is disabled.

I am not looking for general explanations about IMAP, Gmail, filters, server policies, or Thunderbird’s junk logic. I need a concrete, step-by-step procedure that results in:

A visible, usable Junk/Spam folder for max@dantanas.com

inside Thunderbird.

Thunderbird recognizing that folder as the Junk folder.

The Junk settings becoming available so the account can move spam to that folder like all my other accounts do.

To be clear:

All my other accounts in Thunderbird already have functional Junk/Spam folders.

The problem is isolated to this one account.

I need an exact sequence of steps that I can follow to fix it, not abstract descriptions or background information.

Please provide a direct, step-by-step set of actions that will enable Thunderbird to create or use a Junk/Spam folder for this account.

Thank you, Max Makowski max@cape-co.co max@luck.fish

Hello community!

I use Thunderbird desktop for two emails: personal outlook.com (ms365 or whatever ma calls it) and school exchange account.

Exchange works fine using owl and is able to sync calendar correctly. For personal email, it appears I can only connect via imap instead of MS’s protocol, which limits its ability to sync calendar. I’m wondering if there’s a way to login personal ms email similar to exchange to sync calendar etc.?

Thx in advance for ur help :-)

Have used the SeaMonkey suite for my email since Netscape. It seems the latest version SeaMonkey will not work with Apple’s latest OS on my MacBook Air, and is unlikely to be modified to work. So, my plan was to use Thunderbird, but when I Google to see if it (Thunderbird) is compatible I get an AI generated message that the Thunderbird team is working on a new Apple compliant version. Searching this forum I can find no reference to any Apple compatible version. Anyone with updates on Thunderbird versions that will work on my MacBook Air and the macOS Tahoe Currently happy enough with macOS Sonoma and SeaMonkey, but the nags to upgrade are annoying Thank you for your time Cheers Ralph

I generated a CSR file via the instructions at https://support.mozilla.org/en-US/kb/instructions-smime-certificate-using-csr#thunderbird:linux:tb145 . After submitting and receiving a certificate from a CA, importing it the People tab of the Certificate Manager does not do anything: nothing new appears in the Your Certificates tab.

Where are the private keys associated to the generated CSRs stored? How can I access them to resolve this?

Hi, Having trouble with JUNK mails, from unknown adresses. I've found in "account settings" "Trust junk mail headers set by" might be good for me but no idea which one to choose!

I'm not able to log into yahoo e-mail via Linux Firefox (145.0 (64-Bit)): The error message is "We were unable to log you in. Please try again from another device." I can log in with Chrome (Linux and Windows) and Firefox (Windows). My issue is to switch from POP3 to IMAP in Thunderbird. There the same error message occurs.

I've used TB successfully for many years to access several Yahoo and Googlemail accounts. Windows 10. Recently the Yahoo accounts don't work so I've tried several times deleting and reloading them. This may be a red herring but the trouble seemd to start when I installed TB on a new Windows 11 laptop and failed to load the Yahoo accounts. I've tried following both Mozilla and Yahoo help articles but ultimately success is partial at best (i.e. incoming works, outgoing fails) This is the sequence I have followed

Edited outgoing yahoo server to

 smtp.mail.yahoo.com
 Port 465
 SSL/TLS

External connections-> Create app password App name : Thunderbird Generate

Copied to clipboard ********************

Returned to TB

entered app password 'Something went wrong'

Despite this, after closing the yahoo dialog, TB says 'Account created successfully'!!!!

Inbox appears

Note:server settings now set somehow to IMAP / normal password

Testing outgoing: Message fails, Yahoo dialog login fails Edit outgoing server which remains OAuth2 Changed to normal password

Tried app password - failed Tried normal Yahoo password - failed

Have two email accounts: Outlook and Gmail. They check and pull mail off the servers independently. I would prefer to only have to look in ONE account for my mail. I have chosen Outlook. I am having problems getting Thunderbird to push the emails in my Gmail folders to the corresponding Outlook folders. Is that because it can't be done? In settings for GMail account, under Copies and folders, I push: Sent messages > Sent on d*******1@outlook.com Archives folder > Archive on d*******1@outlook.com Drafts > Drafts folder on d*******1@outlook.com but they don't seem to be going there.

Is there a way to move messages in GMail TRASH to Outlook DELETED? As you can see, I'm not very aquainted with these things and am pretty confused. Any help appreciated.

I have two accounts with Thunderbird (*@talktalk.net and *@tiscali.co.uk). Each account will receive incoming emails (with or without attachments - single addressee or part of a group email). Periodically outgoing emails are blocked, with the error message 'Sending of the message failed. An error occurred while sending mail. The mail server responded: Reject for policy reason. Please check the message and try again.' Usually the issue seems to fix itself - this tome it has lasted longer than usual. Please can someone suggest a remedy? Tony

• Bulleted list item

I have built up a collection of more than 400 deleted emails in my 'Deleted' folder. I am sure I will not need to refer to any of them again, and I would like to finally remove them. In the past, there was a command among the various sets of commands at the top of the page, which removed all of them, after confirming that this is what I wished to do. I can no longer find this command. Please tell me where to find it. If it no longer exists, tell me how to deal with 'deleted' material.

Attempting to add a gmail oauth account in TB fails authentication using verified account password. (The account requires two-factor authentication using an authenticator app, but haven't tried that as a password) I have removed the account from TB, and the saved passwords for the account. I then added the account back to TB but get the same "Failed authentication" notification without any opportunity to register a new password. I can not find a cookie to remove and retry the process.

How do I stop all the messages subthreads from being populated on the message tab? For example, with I open a message with subthreads, all the trailing messages are displayed on the tab. The only way to get them off the tab is by clicking the x in every message. A real pain. I don't want this. How do I stop it?
