I do not think it exists, after a fairly extensive search myself. It seems there are a few access compatable software packages out there. I tried one but was not too satisfied and am trying to get my money back from the company as we speak.
I went with an old favorite, Handbase, which is now available for the pocket pc. It is compatable with all those free applets out there (but is NOT directly access compatable), but does come with a fairly good desktop program from which you can also create, edit, and print your database info.
It allows you also to use your palm databases also, if you used handbase on the palm.
