Meeting Responses in a Full-State Oracle Calendar Server to Exchange Migration

How do we deal with Meeting responses in a full-state migration from Oracle Calendar 10.x to Exchange?

• The response options in Exchange are Accept, Decline, Tentative, and No Response
• Oracle Calendar Server allows you to NOT respond to a meeting and it still shows up in your calendar. So in the field lots of people do not bother to actually Accept. Migrating these meetings to Exchange, we insert a non-response as “tentatively accepted” more as a sensible convenience than anything else.
• Exceptions to guest responses to recurring meetings are not inserted. E.g., if a guest accepts all but declines a few occurrences, or declines the recurring meeting but accepts a few occurrences.  The latter situation actually cannot happen in Exchange but is possible in OCS.
