Update Access Table From A Pass-through Query?

I want update a table (in Access 2010) based on the results from a pass-through query that pulls data from an old Fox Pro database.

With the following query I push data into my access table (everything works fine):

Code:

INSERT INTO Bolle ( esercizio, numero_documento, ...)
SELECT Bolle_Arca.[esercizio], Bolle_Arca.[numero_documento], Bolle_Arca.[testata_codice], ...
FROM Bolle_Arca
WHERE
Bolle_Arca.[testata_codice] NOT IN (SELECT Bolle.testata_codice FROM Bolle)

When I try to update the same table using the same pass-through query:

Code:
UPDATE Bolle INNER JOIN Bolle_Arca ON Bolle.riga_codice = Bolle_Arca.riga_codice
SET Bolle.esercizio = Bolle_Arca.esercizio
, Bolle.numero_documento = Bolle_Arca.numero_documento, ...
WHERE Bolle.spedito = False
and Bolle.data_invio_mail_spedito is null
and (Bolle.tracking is null or Bolle.tracking = '')
and Bolle.testata_codice = Bolle_Arca.testata_codice;

I get this error: "Operation must use an updatable query"
