we have an unusual request from HR.
From the HR department, we are asked to certify that a user has rebutted and has received an email warning so that it can be used in court if necessary. The account would be that of an employee but within our domain and platform O365. I believe that even though the "acknowledgment of receipt" is marked if the user deactivates this option in his client, we will not have proof of the arrival or reading of the communication by email. Is it possible to receive an automatic confirmation of an email sent to another user without the user having to give confirmation?
