我在通过 smtp 连接到 office365 时遇到问题。我在这里阅读了所有提示,但没有任何帮助。

调试:

PHP 代码:

$mail = new PHPMailer;
$mail->SMTPDebug = 3;
$mail->isSMTP();
$mail->Host = 'smtp.office365.com';
$mail->SMTPAuth = true;
$mail->Username = 'MAIL@DOMAIN.TLD';
$mail->Password = 'PASS';
$mail->SMTPSecure = 'tls';
$mail->Port = 587; // TCP port to connect to
$mail->setFrom('MAIL@DOMAIN.TLD');
$mail->addAddress('TOMAIL'); // Add a recipient
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';

if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}

最佳答案

你必须在 o365 管理面板中启用它,然后等待 3 分钟并完成

also check $mail->SMTPAuth = true;

enter image description here

使用 Microsoft 365 管理中心在特定邮箱上启用或禁用 SMTP AUTH

Open the Microsoft 365 admin center and go to Users > Active users.

Select the user, and in the flyout that appears, click Mail.

In the Email apps section, click Manage email apps.

Verify the Authenticated SMTP setting: unchecked = disabled, checked = enabled.

When you're finished, click Save changes.
