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

;  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.

;  In case of shared mailbox access using OAuth, the application needs to obtain the access token on behalf of a user
;  but replace the SMTP username with the email address of the shared mailbox.

;  Login using the shared mailbox email address for the username, and the access token for the password.
;  See Office 365 SASL XOAUTH2 format 

;  Use your Office365 email address for the SmtpUsername.
