On our GW8.0.1 system, we've got everyone's mailbox configured to auto-archive all mail/appts over 2 years old. What we are seeing is that sometimes the UNREAD messages don't get auto-archived. But sometimes they do.

There doesn't seem to be any rhyme or reason to the pattern. For person "a", their unread messages over 2 years will auto-archive. For person "b", we have to manually archive the unread stuff over two years.

This doesn't seem to be an PO-specific issue as we're seeing it across all post offices.

Any ideas as to what would cause this?
