OAuth2 SMTP

[Bastian Seidemann]

Hi,

i try to send E-Mails using Oauth2 Microsoft SMTP.

that is my iTop Mail Config:

'email_transport' => 'SMTP_OAuth',

    'email_transport_smtp.encryption' => 'STARTTLS',

    'email_transport_smtp.host' => 'smtp.office365.com',

    'email_transport_smtp.port' => '587',

    'email_transport_smtp.username' => 'xxxxxxx@domain.de'

That is what Microsoft needs to Authenticate against SMTP:

Servername: smtp.office365.com
Port: 587
Verschlüsselungsmethode: STARTTLS

The Answer i get on Mail Test is:

Error: 'cannot connect to host; error = stream_socket_client(): unable to connect to tcp://smtp.office365.com:587 (Connection timed out) (errno = 0 )'

i think the library does not support STARTTLS as Auth.

is there someone getting Microsoft SMTP Oauth to work?

Thanks!

and still use smtp.
// email_transport: Mean to send emails: PHPMail (uses the function mail()), SMTP (implements the client protocol) or SMTP_OAuth (connect to the server using OAuth 2.0)
// default: 'PHPMail'
'email_transport' => 'SMTP',

// email_transport_smtp.encryption: tls or ssl (optional)
//  default: ''
'email_transport_smtp.encryption' => 'tls',

// email_transport_smtp.host: host name or IP address (optional)
//  default: 'localhost'
'email_transport_smtp.host' => 'smtp.office365.com',

// email_transport_smtp.password: Authentication password (optional)
//  default: ''
'email_transport_smtp.password' => 'yourpassword',

// email_transport_smtp.port: port number (optional)
//  default: 25
'email_transport_smtp.port' => 587,

// email_transport_smtp.username: Authentication user (optional)
//  default: ''
'email_transport_smtp.username' => 'your mail',

dont forget to add smtp auth to your user

Do you have more info on your case, Remi?

An exact error message, or does it just keep spinning or ...?
Did you properly set up the OAuth 2.0 client?
