Using OLE-DB, Endicia Professional can natively connect to Microsoft SQL Server, Microsoft Access, Microsoft Excel, Microsoft Visual FoxPro, and CSV text files. However, if you have some other database type or you use only an ODBC data source, you may be able to use ODBC to connect Endicia Professional. If you use ODBC, you must create an ODBC Data Source Name (DSN) for your database before creating a connection to that database.
