Change notification frequency unexpectedly dropped

Hello,

We have developed an integration with the MS Graph API which enables our clients to perform surveillance of the messages sent in Microsoft Teams (for compliance purposes).

This integration leverages change notifications to retrieve MS Teams messages and has been operational for several months now.

A client of ours has recently reported a sudden decline in MS Teams messages captured by this integration and, after carrying out an investigation, we have concluded that we are receiving significantly fewer change notifications than usual via our WebHook endpoint. We typically receive 3k-4k change notifications per day but have only been receiving ~1k per day lately.

From our internal logs, the decline in change notifications appears to have started approximately around the week of 19th September and is still noticeable today (11th October).

We are happy to provide you with the Azure App ID of our MS Graph integration, if required.

Any assistance with this matter is greatly appreciated.

Regards,

Darren.

    Hello @Darren Ruane

    Since it is a tenant-specific issue and in case if this issue is still persisting, I would recommend you raise a support case with Microsoft Graph, a Support Engineer will be able to assist you better. You can raise support ticket from
    http://aad.portal.azure.com/ or https://admin.microsoft.com/#/support/requests.

    Hope this helps.
