We have an executive admin who is an assigned delegate for our company's CEO. There have been several occasions when the admin will add an "all day" event spanning multiple days (i.e. a business trip) to the CEO's calendar and then also send invites to place the same event on other people's calendars (for informational purposes). The next day when the admin looks at their calendar, and the CEO's calendar the event has been pushed back 1 day. Meaning the event/meeting was originally scheduled for Tuesday through Thursday is now scheduled for Wednesday through Friday. Then when the Admin move the event back to the proper date range the system will still sometimes move the event back to the wrong day. The most recent example was this week and the CEO did not change time zones for this trip.
We are running Outlook 2010 and Exchange 2010, the CEO has both an iPhone and iPad that are connected to the Exchange server via ActiveSync through MaaS 360. Both iOS devices are currently running iOS 7 but this issue has been going on since before they upgraded from iOS 6 to iOS 7.
Any ideas as to why Outlook/Exchange is doing this? As well as any solutions for how to resolve it? To my knowledge no one else is having this issue with their calendars.
