There are several ways to prevent duplicate entries from appearing in an Outlook calendar. One of the most common causes of duplicates is importing them when merging calendars, or importing entries from another file or program. Other causes include having duplicate entries in your Outlook Contacts, accepting invitations or scheduled meetings that you have already entered into Outlook, and syncing duplicate entries from a mobile device that have already been entered into Outlook on your computer.

Importing Calendar Files Without Duplicates
Click on your Outlook Contacts and look for duplicate entries. Use one contact entry for each person and use the applicable fields to store multiple phone numbers or e-mail addresses. You should not, for example, have separate contact profiles for work and home information.
Open your Calendar and look at what you already have scheduled before accepting any invitations or meeting requests. If you find you have already inserted an entry for a meeting, or accepted a separate request for the same meeting from someone else, delete that entry before accepting the new request.
Sync your mobile device with Outlook before and after making changes to your Outlook calendar. If you have added an entry in the device, or accepted a meeting request on your device, then repeat that action on your computer, it can result in a duplicate entry on the Outlook calendar.
