This is going to sound like a stunningly stupid series of questions, but I was brought into this discussion/problem in the middle and I really don't understand much about Microsoft CRM. A client of mine is going to want me to figure it out and hopefully deploy/maintain it, and I don't even know where to begin.

This is what I appear to understand:

1. Microsoft CRM integrates with Outlook to provide tracking mechanisms for sales, service and marketing campaigns.
2. Microsoft CRM requires SQL Server and is incredibly resource-heavy.
3. Microsoft CRM is easily customizable, although I can't find a single demonstration to back this claim up.

The question is: what else, if anything, does it do? And how customizable is it? Thanks.

i don't even know what it is.. is it some kind of server software?
