In OWA 2010 I create an appointment on March 10, 2013. I set the appointment to all-day. Instead of the appointment showing as a horizontal bar at the top of that day it displays as a vertical bar and fills the entire day. I was able to reproduce this with multiple accounts and multiple calendars, mailbox and public folder. The issue does not occur on other days. Outlook 2013 displays correctly and the issue does not occur in OWA 2007. It does not matter if the appointment is created in Outlook or OWA. Does anyone know what is causing this?
