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

loMailman = CreateObject('Chilkat.MailMan')

loMailman.MailHost = "outlook.office365.com"
loMailman.MailPort = 995
loMailman.PopSsl = 1

*  Use your O365 email address here.
loMailman.PopUsername = "OFFICE365_EMAIL_ADDRESS"

*  When using OAuth2 authentication, leave the password empty.
loMailman.PopPassword = ""

*  Load our previously obtained OAuth2 access token.
loJsonToken = CreateObject('Chilkat.JsonObject')
lnSuccess = loJsonToken.LoadFile("qa_data/tokens/office365.json")
IF (lnSuccess = 0) THEN
    ? loJsonToken.LastErrorText
    RELEASE loMailman
    RELEASE loJsonToken
    CANCEL
ENDIF

loMailman.OAuth2AccessToken = loJsonToken.StringOf("access_token")

*  Make the TLS connection to the outlook.office365.com POP3 server.
lnSuccess = loMailman.Pop3Connect()
IF (lnSuccess <> 1) THEN
    ? loMailman.LastErrorText
    RELEASE loMailman
    RELEASE loJsonToken
    CANCEL
ENDIF

*  Authenticate using XOAUTH2
lnSuccess = loMailman.Pop3Authenticate()
IF (lnSuccess <> 1) THEN
    ? loMailman.LastErrorText
    RELEASE loMailman
    RELEASE loJsonToken
    CANCEL
ENDIF

*  Find out how many emails are on the server..
lnNumEmails = loMailman.CheckMail()
IF (lnNumEmails < 0) THEN
    ? loMailman.LastErrorText
    RELEASE loMailman
    RELEASE loJsonToken
    CANCEL
ENDIF

*  Examine the POP3 session log:
? loMailman.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
*  < +

*  < +OK User successfully authenticated.
*  > STAT
*  < +OK 3 375302

*  End the POP3 session and close the connection to the GMail server.
lnSuccess = loMailman.Pop3EndSession()
IF (lnSuccess <> 1) THEN
    ? loMailman.LastErrorText
    RELEASE loMailman
    RELEASE loJsonToken
