Both events will fail at around 16 or more items coming in at the same
time. It's a known thing due to the underlying MAPI notification
limitations

there are no real workarounds other than scanning the Inbox at intervals
to sweep items that might have been missed.

What's the most efficient way of doing that? By that, I mean that scanning

in the Inbox have been processed from one sweep to the next? I don't really
want any sort of database functionality here...
