# 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.
