Hi Robert,
Access 2003 format works, using 2007 application to operate it. The client
has a mixed 03/07 environment so all of the front ends are in 03 (mdb) or
(mde).
Using ODBC I'm certain it would work - I think I've done it a couple times
in development testing, but not certain, since I have to step back to mdb or
mde to deliver the product.
Cordially,
Gordon
