Question

我正在尝试使用IPM.Configuration.OWA.UserOptions消息通过来自带有UpdateItem的Outlook Web插件的EWS（SOAP）请求更新ReadWriteMailbox消息中的字典元素权限。但是它在响应中失败并出现以下错误：

ErrorAccessDenied: Office extension is not allowed to update this type of item.

我正在使用的UpdateItem请求是一个相当简单的示例，用于通过它的ID更新消息并设置扩展属性的值：

我无法找到任何说明UpdateItem操作允许或不允许的内容的文档（the list should be here）。目前，Graph或Mail API也无法更新Outlook Online签名。如果我最终想要做的事情无法发挥作用，那么我只是浪费了40多个小时的努力而失去了一个客户。： - |

是否有人有任何聪明的解决方法或知道启用此操作的方法？请注意，在服务器端代码中使用EWS托管API目前不是此解决方案的选项。

Answer 1

Outlook不允许加载项按设计创建或更新FAI消息。通常，我们不允许直接修改OWA选项（或任何其他“服务类型”，内部，项目/数据），这可能是一个内部数据结构，可能会发生变化并可能破坏加载项。

如果您的方案特别需要访问Outlook的签名系统，我建议您向UserVoice

提出请求

无法从Outlook加载项使用EWS UpdateItem操作
