//  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.
