PHPMailer com conta hotmail

Olá pessoal Estou precisando de uma ajuda. Utilizo o PHPMailer com Gmail e tudo ok. Mas preciso configurar ele para um conta Hotmail. Já verifiquei na Internet as configurações mas gera erra no envio. Utilizei o servidor SMTP.live.com e porta 587 e tls e até ssl e não gera o mesmo erro. Alguém poderia me informar como eu resolvo esse problema? 019-10-08 20:18:00 Connection: opening to smtp.live.com:587, timeout=300, options=array ( 'ssl' => array ( 'verify_peer' => false, 'verify_peer_name' => false, 'allow_self_signed' => true, ),)

Caro

Paulo, saudações...

Tenta essa configuração, abaixo:

<?php defined('BASEPATH') OR exit('No direct script access allowed.');

$config['useragent'] = 'PHPMailer'; // Mail engine switcher: 'CodeIgniter' or 'PHPMailer'
$config['protocol'] = 'smtp'; // 'mail', 'sendmail', or 'smtp'

$config['mailpath'] = '/usr/sbin/sendmail';
$config['smtp_host'] = 'smtp-mail.outlook.com';

$config['_smtp_auth'] = TRUE; // Whether to use SMTP authentication, boolean TRUE/FALSE. If this option is omited or if it is NULL, then SMTP authentication is used when both $config['smtp_user'] and $config['smtp_pass'] are non-empty strings.
$config['smtp_user'] = 'seu_email@hotmail.com'; // Informe um e-mail válido para enviar e-mail
$config['smtp_pass'] = 'sua_senha'; // Informe uma senha válida do seu e-mail informado acima
$config['smtp_port'] = 587;
$config['smtp_timeout'] = 30; // (in seconds)
$config['smtp_crypto'] = 'tls'; // '' or 'tls' or 'ssl'
$config['smtp_debug'] = 0; // PHPMailer's SMTP debug info level: 0 = off, 1 = commands, 2 = commands and data, 3 = as 2 plus connection status, 4 = low level data output.
$config['debug_output'] = ''; // PHPMailer's SMTP debug output: 'html', 'echo', 'error_log' or user defined function with parameter $str and $level. NULL or '' means 'echo' on CLI, 'html' otherwise.
$config['smtp_auto_tls'] = false; // Whether to enable TLS encryption automatically if a server supports it, even if smtp_crypto is not set to 'tls'.

$config['smtp_conn_options'] = array(); // SMTP connection options, an array passed to the function stream_context_create() when connecting via SMTP.
$config['wordwrap'] = true;
$config['wrapchars'] = 76;

$config['mailtype'] = 'html'; // 'text' or 'html'
$config['charset'] = null; // 'UTF-8', 'ISO-8859-15', ...; NULL (preferable) means config_item('charset'), i.e. the character set of the site.
$config['validate'] = true;
$config['priority'] = 3; // 1, 2, 3, 4, 5; on PHPMailer useragent NULL is a possible option, it means that X-priority header is not set at all, see https://github.com/PHPMailer/PHPMailer/issues/449
$config['crlf'] = "\n"; // "\r\n" or "\n" or "\r"
$config['newline'] = "\n"; // "\r\n" or "\n" or "\r"

$config['bcc_batch_mode'] = false;

$config['encoding'] = '8bit'; // The body encoding. For CodeIgniter: '8bit' or '7bit'. For PHPMailer: '8bit', '7bit', 'binary', 'base64', or 'quoted-printable'.

Espero ter ajudado.
