似乎任何以/ outlook开头的端点都会返回此错误： @H_301_1@GET https://graph.microsoft.com/beta/me/outlook/masterCategories { "error": { "code": "RequestBroker-ParseUri","message": "Resource not found for the segment 'Outlook'.","innerError": { "request-id": "a75d1c9a-c6ae-4b69-83ca-fc0e467a4ad7","date": "2017-12-26T17:23:17" } } }

我已经授权范围mail.read user.read mailBoxsettings.readwrite所以我应该能够访问用户的收件箱类别,但是这个帖子中提到的以“outlook”开头的beta API端点：

https://blogs.msdn.microsoft.com/exchangedev/2017/10/09/new-outlook-apis-in-the-microsoft-graph-rooms-rules-categories-headers-and-time-zones/

无论如何都无法访问,我做错了什么？

请记住,我测试了这个端点,它完美运行：https://graph.microsoft.com/beta/me/mailFolders

但是这一个：https://graph.microsoft.com/beta/me/outlook/masterCategories返回上面的错误.
