To connect to Microsoft Exchange, you can use either a DSN or an ODBC connection string. Both of these methods use the connect function.

Connect to a DSN

To connect using a DSN:

cnxn = pyodbc.connect("DSN=CData Exchange Sys;User=MyUser;Password=MyPassword")

Provide a Driver Connection String

To connect using an ODBC connection string:

cnxn = pyodbc.connect("DRIVER={CData ODBC Driver for Microsoft Exchange};User='myUser@mydomain.onmicrosoft.com';Password='myPassword';Server='https://outlook.office365.com/EWS/Exchange.asmx';Platform='Exchange_Online';Schema='EWS';")
