Sending email not working see attached video.

Hi,

I am not sure why but when I sent an email from frenchy@hexagon******om.au to laurent@hexago*******state.com.au with a working drive folder share it does not send it.

When I click sent the email completely disappear and have to restart again... 

It works if I don't add a folder sharing. 

Could not attach the Video due to size here is the private link:
