Why Do Duplicate Calendars Happen in Outlook?

Before we proceed to the options to fix this, it may help to have an understanding of some of the causes of duplicate calendar entries. Some of the most common causes are:

• Multiple Synchronizations: If you are syncing Outlook with a mobile device, Google Calendar, or another scheduling application, you may inadvertently cause multiple calendar items to appear as duplicate events.
• Import/Export Errors: If you have imported a PST file (Outlook)at some point in the past, it is possible that, due to errors encountered while importing, calendar items could have been copied multiple times.
• Software Glitches: Add-ins or third-party applications, such as software used for back-ups, could, at times, replicate entry calendar items during an update.
• Human Error: You could also accidentally copy and paste or move calendar entries.

Knowing the cause of any duplicate calendar events can be helpful in making sure the duplicating events do not recur.
