You work as a consultant for a Microsoft Partner. You are helping a company deploy Microsoft Dynamics CRM Online.
The company needs an enterprise collaboration solution that integrates with Microsoft Dynamics CRM Online. The solution should allow CRM and non CRM users to have traceable discussions that are available to everyone and easily searched, share documents and information, and allow users to participate in or leave discussions. The company currently uses and would like to continue using Activity Feeds in Microsoft Dynamics CRM Online in addition to using the enterprise collaboration solution.
You need to recommend a solution that meets the company's requirements.
