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

Connect to a DSN

To connect using a DSN:

db, _ := sql.Open("odbc", "DSN=CData Email Sys;")
defer db.Close()

Provide a Driver Connection String

To connect using an ODBC connection string:

db, _ := sql.Open("odbc", "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;;")
defer db.Close()
