* 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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJsonToken = CreateObject('Chilkat.JsonObject')
lnSuccess = loJsonToken.LoadFile("qa_data/tokens/office365.json")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.MailMan')
loMailman = CreateObject('Chilkat.MailMan')

loMailman.SmtpHost = "smtp.office365.com"
loMailman.SmtpPort = 587
loMailman.StartTLS = 1

* 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.
loMailman.SmtpUsername = "SHARED_MAILBOX_EMAIL_ADDRESS"
loMailman.OAuth2AccessToken = loJsonToken.StringOf("access_token")

* Create a new email object
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Email')
loEmail = CreateObject('Chilkat.Email')

loEmail.Subject = "This is a test"
loEmail.Body = "This is a test"
loEmail.From = "MY_NAME <SHARED_MAILBOX_EMAIL_ADDRESS>"
lnSuccess = loEmail.AddTo("John Doe","somebody@example.com")

* Call SendEmail to connect to the SMTP server and send.
* The connection (i.e. session) to the SMTP server remains
* open so that subsequent SendEmail calls may use the
* same connection.
