I was wondering if anyone had attacked syncing SalesForces data with Microsoft Exchange's data.

As, I'm sure my company is simlar to many in that many of our users are constantly in Outlook and use Exchange as a backend to hold Customer addresses and emails in a Global Address list.
Along with having pre-definded Email Groups i.e. USCustomers, that they can quickly send off a quick email to the group of USCustomers that would get sent to many external customer emails.

But at the same time we would like to use Sales Force's great power as our CRM package.
I guess what it comes down to is...Is there anyway NOT to have to update a Customer's email in both Exchange AND Sales Force.

Thanks!
