Office365 Send Email from Shared Mailbox

See more Office365 Examples

Demonstrates how to send email from a shared mailbox, from smtp.office365.com using OAuth2 authentication. Perl

use chilkat();

$success = 0;

# 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.
$jsonToken = chilkat::CkJsonObject->new();
$success = $jsonToken->LoadFile("qa_data/tokens/office365.json");

$mailman = chilkat::CkMailMan->new();

$mailman->put_SmtpHost("smtp.office365.com");
$mailman->put_SmtpPort(587);
$mailman->put_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.
$mailman->put_SmtpUsername("SHARED_MAILBOX_EMAIL_ADDRESS");
$mailman->put_OAuth2AccessToken($jsonToken->stringOf("access_token"));

# Create a new email object
$email = chilkat::CkEmail->new();

$email->put_Subject("This is a test");
$email->put_Body("This is a test");
$email->put_From("MY_NAME <SHARED_MAILBOX_EMAIL_ADDRESS>");
$success = $email->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.  
$success = $mailman->SendEmail($email);
if ($success != 1) {
    print $mailman->lastErrorText() . "\r\n";
    exit;
}

$success = $mailman->CloseSmtpConnection();
if ($success != 1) {
    print "Connection to SMTP server not closed cleanly." . "\r\n";
}

print "Mail Sent!" . "\r\n";
