Exchange App That Does NOT Sync Deletes

What email app will connect to Exchange (not OWA) and allow deletes on the handset to NOT sync (i.e. not delete the source)?

I have a user who wants to delete mail on his Samsung S3 as he goes but not have it affect his Outlook / OWA.

I played with K9 (but it is OWA based for Exchange) and Touchdown (and a few others) but can not find an app that does not sync email deletes.

Your assistance would be appreciated.
