Email as a CRM tool

CIO Today had an article about how Microsoft is changing the nature of CRM. Instead of thinking of CRM (Customer Relationship Management) as a separate tool, MS is using Outlook (it’s email program) as a CRM tool by simply adding enhanced functionality to the tool many businesses already use.
The article reads, in part, “One of the things we’re seeing is Microsoft trying to spin CRM as being more of a day-to-day type function as part of Outlook, Ben Holtz, CEO of Microsoft Partner Green Beacon Solutions told CRM Daily.”
What can we learn from this? Before plunking down money on a stand-alone CRM tool, you might want to CONSIDER if MS Outlook can serve your needs sufficiently.
