... if I change Mapimail to open with Thunderbird, it gets empty and broken.

Leave the mapimail think alone! Thunderbird is not capable of handling that In-built protocol.
Reset your defaults again, choose MAILTO for the Thunderbird default...

It'll work fine!

Not, on my side. It opens Outlook for me, even if I set MAILTO to Thunderbird

Check the Set as Default setting in Thunderbird...

I did that several times

And..., what does your Registry say?

It's empty by me

Interestingly after several reinstalls, now the default setting worked in Thunderbird

This option was always greyed for me, but after completely removing and reinstalling Thunderbird it was empty upon the first run and could be checked. (After that it is grey now on the screenshot)
Now the sendto function seems to be working in File Explorer and Total Commander again.
Thanks for the tips, everybody

After removing and reinstalling Thunderbird, I also have this exact setting now. Thanks again.

For the record: this was the solution. You should NOT associate Thunderbird with the Mapimail file in Sendto because it breaks the Send to Mail Recipient function.
