Office365 POP3 Login with OAuth2 Authentication

See more Office365 Examples

Demonstrates how to authenticate using OAuth2 using the POP3 protocol with outlook.office365.com.

Note: This example requires Chilkat v9.5.0.83 or greater.

Go

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    mailman := chilkat.NewMailMan()

    mailman.SetMailHost("outlook.office365.com")
    mailman.SetMailPort(995)
    mailman.SetPopSsl(true)

    // Use your O365 email address here.
    mailman.SetPopUsername("OFFICE365_EMAIL_ADDRESS")

    // When using OAuth2 authentication, leave the password empty.
    mailman.SetPopPassword("")

    // Load our previously obtained OAuth2 access token.
    jsonToken := chilkat.NewJsonObject()
    success = jsonToken.LoadFile("qa_data/tokens/office365.json")
    if success == false {
        fmt.Println(jsonToken.LastErrorText())
        mailman.DisposeMailMan()
        jsonToken.DisposeJsonObject()
        return
    }

    mailman.SetOAuth2AccessToken(jsonToken.StringOf("access_token"))

    // Make the TLS connection to the outlook.office365.com POP3 server.
    success = mailman.Pop3Connect()
    if success != true {
        fmt.Println(mailman.LastErrorText())
        mailman.DisposeMailMan()
        jsonToken.DisposeJsonObject()
        return
    }

    // Authenticate using XOAUTH2
    success = mailman.Pop3Authenticate()
    if success != true {
        fmt.Println(mailman.LastErrorText())
        mailman.DisposeMailMan()
        jsonToken.DisposeJsonObject()
        return
    }

    // Find out how many emails are on the server..
    numEmails := mailman.CheckMail()
    if numEmails < 0 {
        fmt.Println(mailman.LastErrorText())
        mailman.DisposeMailMan()
        jsonToken.DisposeJsonObject()
        return
    }

    // Examine the POP3 session log:
    fmt.Println(mailman.Pop3SessionLog())

    // The POP3 session log will look something like this:

    // **** Connected to outlook.office365.com:995
    // < +OK The Microsoft Exchange POP3 service is ready. [QwBIADIAUABSADEAOABD...YwBvAG0A]
    // > AUTH XOAUTH2

    // > <base64 string in XOAUTH2 format>
    // < +OK User successfully authenticated.
    // > STAT
    // < +OK 3 375302

    // End the POP3 session and close the connection to the GMail server.
    success = mailman.Pop3EndSession()
    if success != true {
        fmt.Println(mailman.LastErrorText())
        mailman.DisposeMailMan()
        jsonToken.DisposeJsonObject()
        return
    }

    fmt.Println("Finished.")
