DELETE message call return HTTP 403 instead of HTTP 404 when using immutable ids

Describe the bug

Hello,

I'm using Microsoft.Graph C# nuget package version 5.97.0.

I'm getting emails from outlook, process them and delete at the end.

Sometimes during delete attempt, message already doesn't exists in the mailbox. In such a case I get HTTP 404 response. It's normal. But when I use immutable ids - I get HTTP 403 response instead of 404. I think it should be still 404...

Expected behavior

If we want to delete message that doesn't exists we should get HTTP 404 response nevertheless we use immutable ids or not

How to reproduce

1. Get message using Prefer: "IdType="ImmutableId"" header
2. Delete message using id retrieved in step 1.
3. Try to delete the same message again

Expected: second delete call returns 404
Current: second delete call return 403 with content {"error":{"code":"ErrorCannotDeleteObject","message":"Object cannot be deleted."}}

SDK Version

Start by reproducing the DELETE sequence against Microsoft.Graph C# NuGet package 5.97.0: retrieve a message with Prefer: "IdType="ImmutableId"", delete it, then repeat the delete. Compare the second response with deletion using a regular ID; done means the already-deleted immutable-ID message returns HTTP 404 rather than HTTP 403 ErrorCannotDeleteObject.
