It would be benifical to organise your calendar dates advising which days you
would be working from home.  This could be done with a simular option to Out
of office, except by creating a new colour for "working from home".

I think this would be benificial so people could still book conference calls
on these days and the organiser would immediately know when they are in the
office for attendance in meetings

I would be interested in your feedback, please do get back to me on this
