I've edit the Outlook.hol file and add my company holiday to the
calender. However, I now need to flag those days as 'out of offce' or
something like that... What's the best way to do this?

I don't believe it's possible in a holiday file.

Can the Outlook.hol file be edited to add the 'set flag' value?

I don't believe so.
