Information about the .hol (hol) file type

Below is all the information we have available on file about the .hol (hol) file type.

Microsoft Outlook Holiday file. It stores national holiday information for different countries, allowing these to be visible in the calendar in Outlook.

The holiday file is always named "Outlook.Hol". It is a text editable file, and can be customised.

The file needs to be imported into Outlook to have the holiday dates loaded (Outlook → Tools → Options → Calendar Options ... → Add Holidays ...). Loading the holiday dates files causes diary appointments to be made for each date. It should be appreciated that there is no duplicate checking, so importing the file twice will lead to duplicates.
