Disable Invitation Email

[SB-o-matic]

First of all, thank you for putting this up. I am more of a PowerShell type and will like to know how to stop the user from receiving any invitation email at all.
I was looking in code for the part that called the Azure B2B invitation API so that I can set SendInvitationMessage to $false with no luck.

Any help at all will be appreciated.

Thanks!

You can simply comment code which is responsible to send mail in GuestRequestRule.CS file.
request.Status = await InviteManager.SendInvitation(request, profileUrl, domainSettings);

You can test it out once as I did not test it :)
