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

# Use your previously obtained access token here:
# See the following examples for getting an access token:
#    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
#    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
#    Refresh Access Token (Azure AD v2.0 Endpoint).

# To send mail, we'll POST to the following endpoint:
# 
# POST /users/{id | userPrincipalName}/sendMail
# 
# (The special keyword "me" may be used in place of a principal name.)

# Load the files to be attached.

# The body of the POST request contains JSON that specifies the email subject, body,
# recipients, etc.  This example will build the following JSON plain-text email:
