I am being asked by the powers that be at my company what the worst possible scenario is if we keep our Exchange 2000 server running past March 11, 2007 without spending the 4 grand for the hot fix. While an Exchange 2003 or 2007 upgrade is in our near future, we doubt it will happen before this date. At this point, it looks to me like the time stamps on email, calendar entries, etc will be off by an hour for approx 3-4 weeks until the first Sunday in April (old DST date) rolls around. After that point is it safe to assume email and other Exchange objects would have the correct time stamp? My main fear, is the fear of not knowing what to expect. Can someone shed some light or speculate what could happen? Thanks Bret Hanson Systems Administrator Yunker Industries, Inc.
