I have an Exchange Server (2003) account which I access through a variety of means, one of them being the Windows 8 calendar app. I added an appointment to my calendar through my iPhone, which has successfully been synced to the Exchange Server (i.e. it shows up in Outlook Web Access).
However, the appointment is not yet shown in Windows 8 calendar, although all other appointments are shown. I have tried to find a "sync" button in the calendar app (like the one in the mail app), but there does not seem to be one.
How can I manually trigger synchronization with the server?
