Hi,
Dynamics CRM (or MSCRM as well call it) is essentially a CRM product based on the .NET platform. Although the basic CRM flow is almost the same for all CRM products, the architecture of Dynamics CRM differs greatly from other products available in the market.
Since it's based on .NET, it provides seamless integration with other Microsoft products including Office, Outlook, Lync, Skype, etc. One of the major advantages MSCRM has over other CRM products is the ability to install and host it in your own servers;
so your organization data is within your own servers.
You can go through a 30 day trial of Dynamics CRM online (for free) to explore it's features.
