Hi before few day we are trying to connect Dynamic CRM 2015 On premise with Microsoft Social Engagement Configuration but I got the answer is that you have need Dynamic CRM online because CRM on premise is not supported Microsoft Social Engagement Configuration.

 now We have purchase Dynamic CRM 2015 online now but the same problem when I click on Microsoft Social Engagement Configuration then in "Select the Microsoft Social Engagement Solution to connect to :" dropdown list have only none option and no other option is available.

so please help me which type of license is required.

my question is that we have already CRM 2015 online license so it is compulsory to purchase "Social Engagement license" externally to connect CRM online to Social Engagement.

in short please list out how many License is Required for that.
