Why is My Outlook Calendar Duplicating Appointments?
Before we learn how to delete duplicate events in Outlook Calendar, it is important to know the issue.
- Sync Errors Between Devices or Third-Party Apps
The problem of duplication happens when you sync Outlook with another service like Google Calendar or any device. The following situations are:
- Sync settings are wrongly configured.
- You are syncing from more than one source at the same time.
- The calendar data is merged incorrectly.
For example, if your phone and laptop are both syncing the same calendar but using EXCHANGE and IMAP protocols, Outlook may interpret them as duplicate events or duplicate each other’s calendars.
- Repeated Calendar Imports
When you import calendar files second or third time, Outlook generally adds the events again without checking the database for duplicates. This is common when:
- You downloaded the holiday calendar multiple times.
- You imported a previously exported backup of a calendar.
Every time you import a calendar, it will be treated as new data, so the entries will simply get chaotic.
- Shared Calendar or Invite Update Problems
When using shared calendars or updates from meeting invites:
- Any small edit like changing location, date or time can cause a new event to be created instead of updating the existing event.
- Responding or resending multiple invites might result in duplicate entries.
- If there is a problem with guests’ calendars or there are permission level issues, this can also create duplicate entries.
- Outlook Add-Ins or Custom Rules Malfunctions
Sometimes, third-party Outlook add-ins or custom Rules could cause duplicate events, but it is rare; they do the following:
- If automation is enabled, then it might unintentionally paste events on a different calendar without checking existing events.
- Add-ins that sync or backup calendar data might even duplicate an event during the process.
- Damaged or Bugged Calendar Data
Although rare, Outlook is not without bugs! But, you can always run into corrupted issues in calendar files, which can sometimes create:
- Duplicated Calendar folders.
- Duplicate events that you can’t find that look the same (i.e. repeated or phantom entries).
