I noticed that in a certain e-mail thread where the subject matched the name of several calendar items, the calendar items also appear in the thread. That's totally useless to me, because I use my calendar to plan my day-to-day work, so these items don't add value. And either way, they are NOT part of the conversation thread.
I see that including items from other folders in threads is an on/off option with no possibility to exclude folders or item-types. I want to include items from other folders mainly to include sent items in the threads, but I don't want calendar items in my threads.
Is that possible?
Edit: As far as I know there is no built-in setting to achieve this, but perhaps there's a registry key that might control how items of a particula type (in this case calendar items) partake in the conversation view?
