显然，日历共享有两个版本，我将它们称为旧"和新".这些细节并不重要，只要知道这是Microsoft客户(Outlook，OWA等)中的实现细节就足够了.在您的情况下，与您共享日历的人是通过使用旧"方法的客户端进行共享的，而REST API无法访问与该方法共享的日历.我们正在努力解决API中的问题.

Apparently there are two versions of calendar sharing, which I'll refer to as the "old" and the "new". The details aren't important, it's sufficient to know that this is an implementation detail within Microsoft's clients (Outlook, OWA, etc.). In your case, the person that shared their calendar with you did so with a client that used the "old" method, and the REST API doesn't have access to calendars shared with that method. We're working on addressing that problem in the API.

同时，如果共享日历的用户可以删除共享，然后使用Web上的Outlook，iOS上的Outlook或Android上的Outlook进行重新共享，则它应解除对您的阻止. (要求他们的邮箱必须托管在Office 365上.)

In the meantime, if the user that shared their calendar can remove the sharing, then use Outlook on the web, Outlook on iOS, or Outlook on Android to re-share, it should unblock you. (With the requirement that their mailbox is hosted on Office 365).
