I did make the alterations Andrew mentioned. Archiving strategy is now based on age and 0 days is set.
unchecked the overiding settings as well.
Is it possible that it's archiving them but just doesn't sent them to shortcuts or delete them for certain message classes and folders.

Most of what is left is all calendar appointments.
I checked in the archive explorer for some of the missing ones and not finding them Calendar entries are from various months and years.
Also I can open the mailbox and manually choose to archive the calendar entry from mailbox folder
