It depends what you mean by "link" and "full calendar field access".
If you mean "have a linked table in Access which has a field
corresponding to every property of the Outlook Appointment object and
one record for every Appointment in an Outlook folder", as far as I know
this is not possible.
For full access, you need to use VBA code running in Access to
manipulate the Outlook object model. A good place to start looking for
