How do I get LibreOffice to talk to Thunderbird email client in Windows 10.

I understand how to send an email from LibreOffice but I cant work out how to create an association between LibreOffice and Thunderbird within the windows 10 OS

According to your “Answer”: Which versions of LibreOffice and Thunderbird are you using? I’ve made a test using L0 6.3.0.4 on Windows 10 Version 1903 Build 18362.295, Thunderbird 60.8.0 and it works exactly as described in my answer.
Please be aware that this to work requires Thunderbird to be configured correctly (i.e. you must assure that you can send E-Mails from Thunderbird first)

Please also provide an output of:
reg query HKCU\Software\Clients\Mail
from a Windows command line.

Hello,

on Windows systems LibreOffice refers to the default application for Email (there is no special setting in LibreOffice to reference the email program as it is in Linux systems). Thus you need to Start -> Settings -> Apps -> Default apps -> Email (in Windows) and in Choose an app select Thunderbird.

Ok thanks for that. However I have set Thunderbird as the default email but when I use the send, email option in Libre Office it just say there is no email program associated with Libre Office.
Any ideas?
