Hi @34193688

To get a list of deleted event in outlook calendar , we have to run this endpoint https://graph.microsoft.com/v1.0/me/calendarView/delta?startDateTime=2022-01-26T00:00:00&endDateTime=2022-01-29T20:00:00 it will return all the events in this time frame. Also in the response we will receive a delta token in odata.nextLink parameter as shown below 169182-delta1.png



You can save that link to get the incremental changes in that calendarView.

Then delete an event within in this time frame and run the delta token to get the deleted events as mentioned [here]
[2].

You can only obtain deleted items using /delta queries. When calling /calendarView it will give you only the current calendar, not previous iterations of that calendar.

Hope this helps you.

Hello @Sheena-MSFT
I have followed your instructions, however I couldn't get the removed events by querying the next link.
186074-capture-decran-2022-03-23-123019.pngAs you can see in the capture 2, there is only an empty list in the answer. Can you help me fix this problem. Thank you so much

Hi @BlueOcean-6506,

Thanks for reaching out.

You are getting null value because after generating the delta token you have to change (create, update, delete) events in that calendar view time frame.
