具有不同“ displayName”的两个文件夹的相同ID

Question

我对此API提出了请求，并获得了msgfolderroot ID：

https://graph.microsoft.com/beta/me/mailFolders/msgfolderroot

之后，我打电话给我，并得到了一个文件夹列表：

https://graph.microsoft.com/beta/me/mailFolders/root/childFolders

我需要在根目录中找到一个msgfolderroot，所以我从第一个查询中复制了所需文件夹的ID，并在第二个请求的响应中进行了搜索，结果发现两个文件夹可以有一个ID。

请告诉我，这怎么可能？并且，请说明为什么这两个文件夹的childFolderCount和totalItemCount不同？

示例

对第一个请求的响应：

{
    "@odata.context": "https://graph.microsoft.com/beta/$metadata#users('9ee07cfe-3e76-4005-bd2b-258f31aaea72')/mailFolders/$entity",
    "id": "AAMkAGNjZjYwNmU4LTJjYWUtNDJiNC1hNWNhLWMwNzllZWZkMjM0NAAuAAAAAAAJFA5toPC1R7wN_YNAZc4HAQAYGWCmW3joQLGNsVuMcOgpAAAAAAEIAAA=",
    "displayName": "Корневой уровень хранилища",
    "parentFolderId": "AAMkAGNjZjYwNmU4LTJjYWUtNDJiNC1hNWNhLWMwNzllZWZkMjM0NAAuAAAAAAAJFA5toPC1R7wN_YNAZc4HAQAYGWCmW3joQLGNsVuMcOgpAAAAAAEBAAA=",
    "childFolderCount": 20,
    "unreadItemCount": 0,
    "totalItemCount": 0,
    "wellKnownName": "msgfolderroot"
}

具有相同ID的文件夹可响应第二个请求：

{
  "id": "AAMkAGNjZjYwNmU4LTJjYWUtNDJiNC1hNWNhLWMwNzllZWZkMjM0NAAuAAAAAAAJFA5toPC1R7wN_YNAZc4HAQAYGWCmW3joQLGNsVuMcOgpAAAAAAEiAAA=",
  "displayName": "XrmActivityStream",
  "parentFolderId": "AAMkAGNjZjYwNmU4LTJjYWUtNDJiNC1hNWNhLWMwNzllZWZkMjM0NAAuAAAAAAAJFA5toPC1R7wN_YNAZc4HAQAYGWCmW3joQLGNsVuMcOgpAAAAAAEBAAA=",
  "childFolderCount": 0,
  "unreadItemCount": 0,
  "totalItemCount": 25,
  "wellKnownName": null
},

...
