Q: I have three items on my calendar for 3/12. One is a meeting where I am the organizer, one is a meeting where I am an attendee, one is an appointment with no attendees. I apply DST client OS patch, what happens?  I then run rebase tool, what happens?
A: When you apply the DST client patch, all 3 will shift if you are in an effected time zone.   When you rebase your mailbox, only the meeting where you are the organizer and the appointment will shift back.  The meeting where you are not the organizer will not be rebased until that organizer's mailbox is rebased.
