正如杰森(Jason)在评论中说的那样，问题中的限制应该只适用于Active Directory资源，而不是用户级别，现在文档已更改:

As Jason said in the comments, the restriction in the question should only have applied to Active Directory Resources, not on the user level, the docs have now been changed:

Azure AD资源限制

某些限制适用于基于Azure AD 资源(用户，组)，并且超出限制可能会产生错误:

Certain limits apply to Azure AD based resources (users, groups) and may generate errors when exceeded:

最大订阅配额:

• 每个应用程序:总订阅50,000个
• 每个租户:35个订阅
• 在所有应用中，每个应用和租户的组合:7个总订阅

• Per App: 50,000 total subscriptions
• Per Tenant: 35 total subscriptions
• across all apps Per App and Tenant combination: 7 total subscriptions

是由于建议的威力引起了问题，还是我不知道的某个地方的暂时性错误，但是Interwebs的众神对我微笑了，我的代码现在可以正常工作了；即使我没有更改它.

Whether it was a case of the power of suggestion causing the issue, or some transient bug somewhere I don't know, but the Gods of the Interwebs have smiled on me, and my code works now; even though I didn't change it.

在我的情况下，删除和添加权限可能有所帮助吗?不确定.

Maybe removing and adding permissions helped in my case? Not sure.

至少现在有文档.
