Duplicate Notifications from M365

Damacharla, Tirumala 76 Reputation points

I have created subscriptions to receive the M365 calendar events notifications.
When an event is created/updated, I receive 3 notifications.
Could you please advise me to avoid duplicate notifications?

I really appreciate any help you can provide.

    Hi @Damacharla, Tirumala

    It is a known issue when you use the change notification of user calendar event.
    As /events is under the /users endpoint so it also applies to this.

    Hope it helps!
