We have just discovered (to our horror) that Exchange / Outlook is sending email updates to every one of the attendees whenever an appointment is updated in any way (including marking it complete or putting in notes about how the appointment went in the Details box). This has resulted in our clients and prospects receiving copies of (what was supposed to be) internal notes on how the meeting went from our perspective. I was very surprised there wasn't already a discussion for this on the forums (as I thought others must have come up against it). Does anyone have a solution?
