Hi,

I have implemented an integration with Outlook API. We are using the Notifications Rest API to get the notifications on any changes on the users mailbox. It was working fine since quite long time but all of sudden since yesterday, duplicate notification are coming repeatedly. One message notification is coming 20-30 times on webhook. Could you please guide us what is this issue can be? Thank you 138591-screenshot-from-2021-10-07-17-16-22.png

    I too have this issue however not as extreme. For now I have mitigated this issue by implementing a locking mechanism in our distributed task queue. Our duplicate notifications come in within sub 100ms of one another so this approach has worked well for us.
