Symptoms

When an organizer creates a meeting from an iOS device, the attendees receive a meeting request that is one hour earlier than the scheduled meeting time.

Cause

The meeting request sent from Exchange to the attendees has an incorrect start time and time zone information. The following is the tine zone information from the meeting request:

This timezone is 180 minutes (3 hours) ahead of UTC.
Its primary / standard time name is "".
The timezone transitions from daylight savings time to standard time 10/26/2016 2:00:00 AM.
During standard time, time is 180 minutes (3 hours) ahead of UTC.
Its daylight time name is "".
The timezone transitions from standard time to daylight savings time 3/5/2016 2:00:00 AM.

Workaround

Modify the time zone on the EAS client to another region with the same time offset until the DST period ends.
