One of our clients has on premise Microsoft CRM 4.0 Workgroup edition and Exchange, and I'm looking into the possibility of moving CRM off site to a specialist company as a hosted (SaaS) solution.
For what I've learned about CRM, it is quite tightly integrated into Exchange and AD.
If I do move CRM to a company that provide MS CRM hosting, does the system still have dependencies on our AD, and if so, how does this work?
