有关Ews同步项目的一般问题-（syncItems）
正如我从文档中看到的那样，我试图了解操作的结果是"created,deleted,updated"。
Mu场景如下：
我正在尝试计算后续syncItem（状态）之间的所有"deleted"项目，
在EWS SDK方法中看到的
SyncItemsResponse : syncItems(FolderId folderId, ItemShape itemShape, String state)
它仅包含一个考虑状态的参数，因此我在每两个同步之间进行一次计算
example:
`SyncItemsResponse:syncItems(state1 - state2) = delta is "what created/deleted/updated between the states.`"
但是我在"deleted items"中遇到了奇怪的结果...。while created Items随着时间的流逝而减少（从2017年开始的状态……至今）
deleted items一次又一次地下降。...
我已附上屏幕截图：
这是循环（i = 0,1,2 ...）中状态的迭代-
// I'm calculating => (next - current) = delta

我的问题是"deleted items"也没有减少而创建时却没有减少的原因是什么？
我是否缺少syncItems的基本功能？
请咨询
