To connect to IMAP, you can use either a DSN or an ODBC connection string. Both of these methods use the Database's Open method.

Connect to a DSN

To connect using a DSN:

var db = new Database();
db.open("DSN=CData Email Sys", (err) => {
    // Use the connection
});

Provide a Driver Connection String

To connect using an ODBC connection string:

var db = new Database();
db.open("DRIVER={CData ODBC Driver for Email};Port=993;Server=outlook.office365.com;Password=password;User=user;Protocol=IMAP;SMTP Port=587;SMTP Server=smtp.office365.com;;", (err) => {
    // Use the connection
});
