When your all day events span two days, it means the time zone is different from the time zone used when you created the events.

If you are syncing with a PDA, verify the time zone and daylight time settings are the same (and the correct one for your location) on both computers.

If the events span two days only in March, verify the 2007 Time Zone update is installed. See Daylight Saving Time Updates for more information.

How to Fix

When the time zone change is permanent, use the Microsoft Office Outlook Tool: Time Zone Data Update Tool for Microsoft Office Outlook to move the appointments.

Alternately, you can set the computer so the times are correct, export the calendar to Excel or CSV format. Once exported, correct the clock so the times are correct then delete the appointments from the calendar and import the file.

    We have an international business with a shared Administration calendar - we include things like public holidays, birthdays, periods of leave - when they are entered as an all day event, we need them to stay as an all day event, regardless of timezone. This change to them spanning 2 days is a new issue that we didn't experience previously. Is there a way we can stop this from happening? Our time zones on each computer are correct.

      What version of Outlook? If 2010 or 2013, they should stay on one day. Older versions of Outlook will show them on 2 days as the zones change.

      This happens when the event was created in a different time zone but should only occur if the event is a meeting. All day appointments should stick to the day. If the event was created in an older version of Outlook and in a different time zone it will usually cover two days.
