[O] Request for advice

[Carson Chittom]

I don't want to duplicate a bunch of effort if this is already a solved
problem, so I'd like some advice, if anybody is or has been in a
similar situation.

Previously, I worked in a situation where I set my own schedule, and I
used Org to keep track.  Beginning next month, I will be working in
place where there will be quite a few meetings (several of them
regularly-scheduled status-type ones, but others are ad hoc) and I'll
need to coordinate my schedule with 15-20 other employees.  They
currently use Microsoft Exchange/Outlook calendaring to coordinate.  But
I'd like to continue to use Org (I have no authority over others'
software).  What I had originally envisioned was:

        1. Keep my own schedule in Org.
        2. Friday afternoons, export next week's agenda as a .ics file
           and import it into Outlook, so that others who need to can
           see my free/busy times.

A quick test showed me that if I did my org files as is, I would end up
with multiple items in Outlook of my regularly-scheduled meetings (most
are weekly, but there are also several monthly, biannual, etc).[1] In
addition, but less pressingly, I have a few items whose date is
determined by a sexp, and so aren't exported (which as I understand it
is the fault of icalender.el, not Org).  I also can't really do exports
of any more than a week, since even the regular meetings could
conceivably change, which, again, would give me (in this case, wrong)
duplicates to clean up.

Several ideas occurred to me:

        1. Add all the regular meetings to Outlook manually.  In Org,
           give them all a particular tag, and configure the agenda
           export to export everything except that tag.  In the event
           that one changes, edit both in Outlook and Org.  
        2. On Fridays before I export, create new instances of all the
           regular meetings (i.e., so that at export-time, the meetings
           beyond the next week don't exist in Org).  
        3. Give up.  Just keep it in Outlook.

Can anybody speak to what the best way to do what I want is, with the
least amount of (ongoing) effort?  Any gotchas I should look out for?
