The specified object was not found in the store., The process failed to get the correct properties.

Hi,

I've set up a change notification using the Microsoft Graph API so that Microsoft sends webhook notifications to our server whenever a new email arrives in a specific mailbox.

Each notification includes the ID of the new email. Our server then uses this ID to retrieve the email body via an HTTP GET request to Microsoft Graph.

However, we've encountered a few instances where the server receives a error when attempting to retrieve the email. The error message is:

Error Message: Exception: Microsoft.Graph.Models.ODataErrors.ODataError: The specified object was not found in the store., The process failed to get the correct properties.

Has anyone experienced this before or have any insights into why this might be happening?

Thanks!
