Outlook 2010 calendar works fine when I add an "all-day" appointment, but appointments with specific times simply disappear once I click to save them (they never appear on the calendar). This behavior is consistent on all (5) computers I've tried, some with and others without the service pack installed. Any ideas what might cause this problem?



Thanks,

Im an Outlook 2010 user, and this does not happen to my program connected to exchange. When you create an appointment, that has a start time and a finish time, what is your default calendar view as weel as the time zone you set the appointment?\

Also are you setting it in the proper Calendar?

When you have a shared calendar unless you have the proper permissions to add or edit events, you will not be able to add appointments.

Keep me posted.

I had been using the month view, and figured out the solution when I switched from month view to week view and suddenly all of my timed appointments appeared. Somehow my month view setting had been switched to "show low detail"--a setting that I didn't even know existed--and once I switched it to medium or high detail all the missing appointments appeared! )
