how to auto-create outlook profile when user needs to send mail from a "RemoteApp"?

Hello,

we have office 2016 and we have a program as remoteapp that can export to excel. when users try to send this excel (spawned from the remoteapp) as mail the user gets this error:

and then:

Mail system failure. check you mail installation

i read in some posts that this reg key should help (ive also tried not in polices):

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\AutoDiscover

Dword = ZeroConfigExchange

Value = 1

but i get the same error.

is there a way to auto create the mail profile when an application requires it? or maybe i can run some app that will auto-create the profile on first login?

thanks,

Sean
