I have a custom email client integrated in our CRM system and I want to give my users the option to register it as a default email client in Windows. I have modified the registry keys and I'm now able to select my application as the default mail client, but when I click the 'Send.' Button in for instance Paint I get this error 'Send Mail failed to send mail'. My application is an executable and works fine when using mailto links, but I suspect the default email integration fails because I use the same executable in the DLLPath under 'HKLM SOFTWARE Clients Mail MyMailBox'. Is there someone who knows how or what I need to do to get this working?
