If an inquiry is processed thru Owner Rez does that update the VRBO calendar associated with the property?
Inquiry or booking? Inquiry is just a question, like "how many steps to the beach?". Once you have the BOOKING and IF you have sync/import/export OR calendar set up on VRBO, then yes, it will update VRBO (or any other synced) calendar. You have to set up import of OR calendar on VRBO and vice versa.
