使用PHP Outlook Web Access时出错：通过OWA API访问Microsoft Exchange Web服务

我使用的是PHP Outlook Web Access：通过OWA API访问Microsoft Exchange Web服务的唯一目的是访问用户的日历约会。所有用户都可以正常工作，但对于某个特定用户，错误显示为：

Message: Use of undefined constant _DEBUG_ - assumed '_DEBUG_'

Filename: classes/connection.php

Line Number: 51

There was a problem parsing your XML!

                WHERE NOT "urn:schemas:calendar:instancetype" = 1
                AND "DAV:contentclass" = 'urn:content-classes:appointment'

                ORDER BY "urn:schemas:calendar:dtstart" ASC

在此链接中，它提供outlook express的链接。为什么会这样？是配置问题还是我做错了什么

欢迎提供任何帮助/建议。提前感谢。

伙计们发现了问题区域，问题是用户存储在两个单独的exchange帐户中，我只使用其中一个，而不使用另一个。

Hi@sammy我正在尝试集成PHP Outlook web access，但出现440登录超时错误。您是否有仅用于验证用户身份的示例代码？？请让我知道
