* An Office365 OAuth2 access token must first be obtained prior
* to running this code.

* Getting the OAuth2 access token for the 1st time requires the O365 account owner's 
* interactive authorizaition via a web browser.  Afterwards, the access token
* can be repeatedly refreshed automatically.

* See the following examples for getting and refreshing an OAuth2 access token

* Get Office365 SMTP/IMAP/POP3 OAuth2 Access Token
* Refresh Office365 SMTP/IMAP/POP3 OAuth2 Access Token

* First get our previously obtained OAuth2 access token.

* Connect to the Office365 IMAP server.

IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loJsonToken
    RELEASE loImap
    CANCEL

* Use OAuth2 authentication.
loImap.AuthMethod = "XOAUTH2"

* Login using our username (i.e. email address) and the access token for the password.
lnSuccess = loImap.Login("OFFICE365_EMAIL_ADDRESS",loJsonToken.StringOf("access_token"))
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loJsonToken
    RELEASE loImap
    CANCEL
ENDIF

? "O365 OAuth authentication is successful."

* Do something...
lnSuccess = loImap.SelectMailbox("Inbox")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loJsonToken
    RELEASE loImap
    CANCEL
ENDIF

* Your application can continue to do other things in the IMAP session....

* When finished, logout and close the connection.
lnSuccess = loImap.Logout()
