Our executive administrator has a knack for stumbling into every glitch and quirk with Outlook! This time she is running into an issue where an event scheduled from 9:40 to 9:55 is displaying on calendars as overlapping past 10:00. The meeting times are entered correctly in the meeting details, it's just the calendar's visual time slot that is displaying incorrectly.
Her mail client is Outlook 2010 64-bit and her mailbox is on an Exchange 2010 server. I checked in OWA and the meeting displays in correctly there as well. I also checked the recipients OWA account it displays incorrectly for him as well. So it is definitely not a client view settings issue.
