If a Web browser user creates an All Day Event that spans across years (for example, start date is 12/21/98, end date is 1/2/99), the user receives the following message when switching fields:
The End Date for the meeting must be later than the Start Date of the meeting
In order to work around this, the user should re-enter the End Date of the event and then immediately click the Save and Close button. If they enter information in another field after changing the date, they receive the same message, so the order of execution is extremely important.
