; 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.
