Question

我们正在使用Microsoft graph API进行日历和邮件项目处理。我们从office 365帐户中选择项目，处理该项目，然后将其标记为已读，然后删除该项目，以便不再对其进行处理。在标记项为读取过程中，我们有以下方法

MarkReadMail()

{

var response = graphClient.Me.Messages[itemID].Request().Select("IsRead").GetAsync();

var msg = response.Result;

msg.IsRead = true;

graphClient.Me.Messages[itemID].Request().Select("IsRead").UpdateAsync(msg);

}

MarkReadMail()在Office 365商业基本帐户上可以正常使用，但在客户端使用Office 365企业帐户，则出现以下错误：

Message: Exception occured in method MarkReadMail  :Code: ErrorAccessDenied
Message: Access is denied. Check credentials and try again.

尽管如此，我们在两个帐户的委派权限下都提供了Mail.ReadWrite权限。

请提出建议。

您无法发布从GET接收到的对象，因为该对象包含只读属性（即id）。您需要发布一个仅包含您要更新的属性的新对象：

graphClient
  .Me
  .Messages["itemID"]
  .Request()
  .UpdateAsync(new Message(){ IsRead = true });

更新邮件项目的IsRead属性时，Microsoft Graph API中的ErrorAccessDenied
