Have you thought of testing it?
Just add a record in Max, see what happens. Change the flag, add another record to Max, see what happens. Add another record to the Outlook, see what happens. Change the flag, add another record to Outlook, see what happens. Try the same type of thorough, yet very simple testing, when you simply change a field?
Document the results. Maybe even share them with the rest of us?
Just a thought.
