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.

    (Following on from Diane's reply of February 27, 2014 at 9:16 pm) I am using Outlook 2013 and have events going back several years years i.e. created in older versions of Outlook. All day events created since installing Outlook 2013 (365 in fact) stick to one day in Outlook and also in my Android phone when I sync (using Akrutosync). However, the older all-day events (created pre-Outlook 2013) span two days on my phone. I move around a lot and I don't think the permanent time zone fix (timezone update tool) recommended above will work for me. Is there another way to get all-day events to stick to one day in Outlook and on an Android phone?

      As far as I know, you'd need to recreate them - the older versions of Outlook didn't handle all days events in the same manner - but I will check and see if a macro can set a property to make outlook think they were created in 2013.
