Hello,
My application listens (webhook) to pings from Microsoft Graph subscriptions (https://graph.microsoft.com/v1.0/subscriptions) so every time a NEW email arrives in our inbox I get pinged on the notificationUrl.
Since yesterday night we started seeing a behaviour where all of the past messages already in our inbox is triggering a webhook call to our system so at the moment we are getting thousands of requests in our webhook. I would like some help to understand what is happening and if there's any way for you to stop sending those pings and only trigger it for NEW emails only.
Thanks
Julio
