Larave 利用smtp.office365.com發送郵件遇到問題

參考：https://stackoverflow.com/questions/52765247/expected-response-code-250-but-got-code-554-with-message-554-5-2-0-stor-edr

.env配置如下：

MAIL_DRIVER=smtp
MAIL_HOST=smtp.office365.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD='xxxxx'
MAIL_ENCRYPTION=tls
           

報錯資訊：

Expected response code 250 but got code “554”, with message "554 5.2.0

STOR

EDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied;

Failed to process message due to a permanent exception with message

Cannot submit message.

原因：

off365的發件人必須和登入使用者一緻。

在laravel中的config/mail.php可以看到

'from' => [
        'address' => env('MAIL_FROM_ADDRESS', '[email protected]),
        'name' => env('MAIL_FROM_NAME', 'Example'),
    ],
           

解決辦法：

在.env增加一行配置：

MAIL_FROM_ADDRESS=(這裡的位址和MAIL_USERNAME相同)
