Overview

When there are a lot of meetings/appointments/events (about 8000) in your Calendar, then, Outlook may not show all of them at one point and they would disappear. Reinstalling Outlook doesn't help as it would fix the issue for a few days and all the meetings would then again go missing. This article provides the steps to remove or archive older Calendar items so that their count would reduce.
