The Notes calendar action to import holidays out of the directory creates the entries in the users' calendar. The calender document have the property "Mark time as" with has to be either "Free" or "Busy".
I as a user from Germany who likes to have the holidays of some other countries in my list fail with this, because my time is blocked in case the source entries are marked with "busy". In case the entries would be marked as "free" the users in this country would fail to block their time.
Please provide an option with the Import to either mark the entries busy or free when the user runs the report. DOn't let the document make the choice.
