However, my tests show that Outlook tries to move the deleted items to the
wastebasket folder of the _my_ store, not the primary store. Furthermore, if
I don't return the wastebaset in the valid folder mask, and don't return an
entryid for PR_IPM_WASTEBASKET_ENTRYID, Outlook simply reverts to the same
"delete permanently" behaviour it always had before I set the
storetypeprivate property.
In other words, it seems that effectively marking the store type private
only made my webviews work, and had no other functional effects on my store.
Given that my store doesn't support sending email (so no drafts etc), only
storing it, can I now safely assume that there are no further side-effects?
