Please help. I need to open an Access 2000 database (which is on a
network
server) from inside Outlook 2000, using a macro assigned to a toolbar
button.

If it can be done.

Yes, you have to learn how to use ADO to open a connection to the database
and then open a table or execute a query within the table. This the returns
a recordset which you can walk through processing each row as required.
