Please be advised that a bug in Outlook 2016 for Mac may cause an event’s start time to be displayed incorrectly following Daylight Savings Time (DST). When a user views their calendar in Week view (i.e., Monday through Sunday), event start and end times are not reflecting DST and are shifted one hour ahead. When viewed in Work Week or Month view, the event start and end times are displayed correctly.
This issue is not limited to the PennO365 tenant. Microsoft is aware of the problem and is investigating. For more information, please see:
