Enable Duplication Removal

Calgoo can automatically delete duplicate events by checking your new and modified events during synchronization. These events will be deleted in Calgoo Calendar and from the calendars you synchronize with. By default, this feature is disabled and it can be turned on and configured from the toolbar. This feature only works on calendars which synchronize and to which you have full read/write access, so a local Calgoo Calendar will not have its events automatically checked for duplications.

To remove your duplicated events, follow these steps:

  1. Click the Manage button at the top of the Main pane and select the Event Duplication Settings option.

  2. Select the Automatically remove duplicate events from my calendars option. If you wish you can also select other criteria such as Location and/or Attendees.

    Please note that:

    • Events are matched for duplicates based on a set of matching criteria. Events must have a matching summary and time, including recurrence, in order to be considered duplicates. We also recommend that you select the "Original Calendar" option as well, as this will ensure that events originally from different sync sources, which may appear the same, are not accidentally deleted. You can also further restrict how a duplicate event is determined by having Calgoo match the location field and the attendees. Checking more criteria reduces the number of events that are removed.
    • Events are never matched across calendars. Event duplicates are only found by comparing events from the sync sources in the calendar, never with sync sources from other calendars.
    • If you have an existing calendar which has duplicate events, or if you want to delete duplicates quickly from a non-synchronizing Calgoo Calendar, please perform a calendar cleanup.
