    I'm using office 356 and I can't use SentAS or on behalves of because I don't have admin permission to access and change. I want to go around that and using C# to overcome this issue.
    I tried to use emailMessage.Sender = "myEmail@réalisations .com"; but it still pointing to the different email in office 356 setup as default email.
