检查约会在日历 iteself 中修改或由 EWS API

Question

I am trying to sync calendar items to our application by using a windows service. So i sent appointments to outlook calendar. Later i just want to pull appointments which are modified only in calendar. Is that possible, If i am using same login parameters? Or is there any other parameters i can check? Already checked IsDirty & it is always false.

When you update an appointment (or any Exchange store items) you should get back the changeKey for that item in the response https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/ews-identifiers-in-exchange so you can use that to track further changes or to filter out clientside changes depending on how you syncing the items.
