Reporting Services因OAuth变更无法通过Office 365 SMTP发邮件求助

我们环境部署了Windows Server 2012 R2和SQL Server 2016，Reporting Services（SSRS）通过Office 365的SMTP服务器发送邮件。之前采用用户名密码的Basic认证方式一直正常，现在突然失效。推测是因为微软要求Office 365 SMTP必须使用OAuth认证，但SQL Server 2016的SSRS中没有明确的OAuth配置选项。

以下是报表日志中的错误信息：

ERROR: Error sending email. Exception: System.Net.Mail.SmtpException:
Failure sending mail. ---> System.IO.IOException: Unable to read data

编辑说明：抱歉，之前提供的错误信息有误。

请问有没有人遇到过SSRS邮件发送的这类问题？有没有可行的解决方案？
