Whats the difference between inviting someone to a meeting & scheduling a meeting for them as a designate?
The difference between inviting someone to a meeting and setting up a meeting for someone as their designate is Ownership. When you invite someone to a meeting, you own that meeting and are the only person who can edit that meeting. If you remove yourself from the invitee list, it becomes very difficult to edit/change/delete that meeting; as no other users can manipulate that meeting. If you have been given designate rights to create meetings for someone, you can open their calendar as a designate (see: Someone told me I have designate rights to their calendar, now what?) and create a meeting for them. The person whose calendar you are creating the meeting retains ownership of that meeting, allowing them to make changes to the meeting when they log on. The designate also maintains the ability to edit the meeting as long as they open the calendar as a designate.
