Tip 859: Remove Duplicate Holidays from the Outlook Calendar

We’ve all done it once or twice: accidentally added Holidays twice or duplicated them when syncing with a smart phone. Or, you added holidays for more than one country and decided you didn’t need all of those countries. Fortunately, they aren’t hard to remove and you don’t have to do it one at a time.

Use a List view and group by category.Delete all then re-add the Holidays. If you have duplicate appointments as the result of importing, you can add the modified field to the view and sort by it. Delete all of the items with the same modified date.

For all other duplicates, a third party utility will make deleting the dupes easier.You’ll find a list of utilities at Duplicate Remover Tools for Microsoft Outlook.

This video shows how to use the group by category view – after enabling the by category view, select the category header and press the Delete key on your keyboard to delete all of the items in the category.
