Hi,
The best practise for controlling staff use of email services is to
implement behavioural policies. You've spelled out the policy on using
company resources and company time for company business. A few well-timed
visits by management to desks of people who FW-1 reports as having more
Hotmail sessions than others will change behaviour better than any other
tactic. It requires less effort.
People using Hotmail establish a browsing pattern. Either the client is
open all the time or it's open at predictable time slots. Your logs will
tell you when to visit the employee for a chat.
You'll notice Hotmail sends a block of scans to various ports on your
gateway so the banner ad hydrants can blast your router with pre-cached
graphics on the next visit to Hotmail. In my experience, I get many more
Hotmail-domain port scans than actual Hotmail sessions.
