Hi Arvind
You can create emails in D365CE either via a workflow or manually to a dummy address or turn off the server profile. Then press send on the email. Install Level up for Chrome or Edge Chromium build and navigate to the email. You should see a rocket in the top right, which is level up, then press "God Mode", this will allow you to change every setting on the form, including the status, allowing you to change it to received.


This will give you the email in the right state, and hopefully might work for you in this scenario.
thanks
Matt
