Create linked exchange server

I'm using sql server 2005 and exchange 2003. End result is I want to upload email attachments to a table in sql. No one seems to have any idea how do do this except with .net, which i know nothing about so not really an option for me. I found this bit of info with some extensive web searching. Can anyone help fill in the blanks? I can't get the linked server to work yet.

EXEC sp_addlinkedserver 'exchange',
'Exchange OLE DB provider',
'exoledb.DataSource.1',
'file:\\.\backofficestorage\mailservername\public folders'

Error received:The OLE DB provider "exoledb.DataSource.1" has not been registered.

Does the Exchange Ole DB Driver exist on the SQL Server machine? I am assuming the 2 services are not on the same machine. If not, you may need to install the Exchange SDK or management tools on the SQL Server to get the OleDB driver installed.
