SYMPTOMS
When you send a new recurring meeting request from a location that is on daylight saving time to someone in one of the states that does not adjust for daylight saving time, such as Arizona or Hawaii, the time of the meeting on your calendar and the time on the other person's calendar differ by one hour. (This one hour is in addition to the normal difference between time zones.)

This behavior occurs only on the changeover days, once in the fall and once in the spring. Any meeting on the calendar from your time zone to an area that does not use daylight saving time is affected.



CAUSE
This behavior can occur because Outlook does not identify the missing hour or extra hour that exists on the night when the 2:00 A.M. changeover occurs.



WORKAROUND
To work around this behavior, manually correct the time differences in your calendar for daylight saving time changeover days.



MORE INFORMATION
Outlook is behaving according to its design, except for the two days of the year when most of the U.S. states change to or from daylight saving time (in the fall and the spring). The time is off by one hour just on the day of change because of when Outlook checks its time zone information (at 12:00 midnight local time for the primary time zone). On the fall changeover day, 2:00 A.M. occurs twice, lengthening that day to 25 hours; in the spring, 2:00 A.M. does not occur at all, shortening that day to 23 hours.
