Thunderbird Support Forum

I have a Windows 11 original OS on my PC computer. I can install Thunderbird and it recognises my MS Hotmail Account and sets it up as normal. When I attempt to set up my gmail account I get the following error message: "Unable to log in at server. Probable wrong configuration, username or password." As far as I can tell all the details are correct. Anyone able to give me an idea how to get this working.

I am setting up a newsletter which will go to my five hundred contacts every day. can I download mozilla thunderbird, and will it be acceptable to do so with that email using another platform email marketing platform? My list has given me permission (signed up) for this, there is no cold emails, but they are forwarded on for several generations, from one person to all their contacts, to theirs ,and on and on. Would this be permissible with thunderbird? I thank you for your attention to this matter.

some messages are displaying as garbled test, I tried all the different html settings in the body display no differences in any of the displays. Messages on wedsite are correct. No updates that I am aware off have occurred. I have rebooted computer and Thunderbird to no effect

Hi, I'm using Thunderbird chat with XMPP and Openfire as XMPP server. My only problem is that I can't transfer file on chat window. However, I can easily send files on other XMPP client such as Pidgin or AstraChat.

So, my question is, does Thunderbird chat support file transfer ?

Thx

I am all of a sudden not receiving emails from group lists I previously have been a part of and my email is in the distribution list. This just started to happen.

Any suggestions? Not very technical here...

I'm new to PC's. I have very basic knowledge of how to use an i-pad. A month ago I got myself a new MacBook. I installed Thunderbird, no problems. My old mail showed up, new mail came in. I installed GNupg.

Following FSF's excellent tutorial I set up Thunderbird with encryption, all good. Now I'm at the point where I 'should try it out' by sending 'Edward' my public key. This worked as I immediately got an encrypted e-mail from 'Edward' in my Apple inbox. However, on Thunderbird I was left hanging with a constantly spinning disc which I presumed meant Thunderbird was trying to retrieve said e-mail. This did not resolve.

After clicking here and there on Thunderbird's interface, I ended up at the account set up screen being prompted for my e-mail address and password. Three weeks had passed and I couldn't remember my password, nor find a note of it. I only have access to account set up and homepage. On homepage I looked through the 'hamburger' menu but I can't find anything that helps. So, I'm locked out of Thunderbird mail.

Any help would be appreciated on both how to resolve the password issue, and what might have gone wrong in retrieving 'Edwards' mail.

Many thanks, Darren.

Has anyone received this message or know how to fix the issue that may be causing it?

The reason for the problem: 5.3.0 - Other mail system problem 554-'5.4.14 Hop count exceeded - possible mail loop ATTR34 [BL0GCC02FT003.eop-gcc02.prod.protection.outlook.com]'

Running 91.9.1, W10. At about noon today I stopped receiving all emails from multiple providers. I have done no updates. Selecting any account results in the looping timer. The mail is available at gmail and aol as well as on my iphone. I've restarted Thunderbird to no avail. All network settings look good. I am running windows defender. As stated I have changed nothing on the PC.

For years when I compose an email, my address book appeared on the left column.

Somehow today it disappeared. How can I get it back to the above location when composing an email?

Hi,

I have a Mozilla Thunderbird email client, which has been linked to my Microsoft Outlook account using IMAP for years, and has operated perfectly well for my personal preferences.

At some point overnight (26th / 27th May) this stopped working and I am now presented with the error message "Sending of password for user xxx@xxxxxxx.co.uk did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password" when trying to download mail.

This is very strange as I can log in directly to my Outlook account using the same user name and password. No settings were changed by me in either Mozilla or Outlook.

For information, I can still send messages from Thunderbird but not now receive them.

Can anyone help, please?

Many thanks.

All the posts suggest

 Please see https://www.mozilla.org/en-US/thunderbird/all/

but that just offers the latest version (current 91.9.1) which won't run on El Capitan.

Other posts tell you to look at

 https://www.thunderbird.net/en-US/thunderbird/releases/

but that only gives you the release notes for the older versions, without any download links.

How do you get the older versions?

Hi, I have an existing installation of Thunderbird 91.9.1 on my linux system. I have a gmail, outlook and web.de mail each running via this installation (IMAP). My new workmail is hosted by 1&1(ionos). I can log in via web interface. Autoconfig finds the configuration that is (according to their help articles) the correct one to access the Mail via IMAP. Incoming: imap.1und1.de SSL/TLS 993 Outgoing: smtp.1und1.de STARTTLS 587 normal Password Username is my full email address. There have been no typos. I checked 5x, copy pasted, rechecked. Pasted it into the web interface login, and thunderbird before clicking go on each -> tb - no, web - yes domain is talsen.team

I would appreciate some pointers to get this fixed. And yes i did read prior questions regarding this error. It did not help in my case.

I made a huge mistake, I was trying to make Thunderbird view larger, now it's much to large to be functional or to make changes or go back to original settings. Here's what happened.

I went into "advanced settings" and changed layout.css.dev.Pixels.Per.Px the size is to large and now I can not view or make changes to Thunderbird. I tried deleting Thunderbird and re-installing it but no luck, the re-install has same large scale issue.

Thunderbird used to ask me for my password on incoming emails but this has now disappeared and mail is automatically downloaded when I open Thunderbird. How do I re-instate this? I have version 91.10.0 on a Mac and have a POP3 account. I am still asked to enter a password for sending mail and would like to keep this feature.
