Written by If you are using CRM 2016 [Version 8.0] and without Update 1 installed, you might notice that Interactive Service form doesn’t have option to include ‘Web resource’ and ‘IFRAME’ component which is a great drawback. Many users have complained about this and Microsoft has fixed this in Microsoft CRM 2016 Update 1 release.
You would now be able to include IFRAME components in Interactive Service forms.
