You can get the contents of any table imported into an Excel worksheet a
couple of ways.
From Excel, choose
Data | Import External Data | Import Data
Then browse to the .mdb file and identify it and choose from the tables
displayed.
From Access you can open a table or query and then choose File | Export and
choose the .xls file type. An Excel workbook with a single sheet will be
created. Both the workbook and the worksheet will have the name of the table.
Eventually you'll end up over in Word and during the Mail Merge process,
just identify the Excel workbook as your data source.
