Answer 1

Hello Saira Munir,

Thank you for reaching out to Microsoft Support!

Even with admin privileges, accessing another user’s calendar requires that the calendar be shared with the signed-in user. Additionally, the Calendars.Read.Shared permission must be granted.

Hope this helps.

Hi @Saira Munir

When this endpoint uses delegation permissions, it also requires Calendars.Read.Shared permission, which you can also use with application permissions Calendars.ReadBasic.All.

You need to register the app in Azure, add this permission to the app, and then use the client credentials flow to get the token. Once you get the token, it is recommended to parse the token in jwt.ms, making sure that the token has the Calendars.ReadBasic.All permission.

Finally, you can send requests through Postman to get tokens and access other users' Calendarview.
