I have two email addresses I got from my college. One is my casual email address and the other is an alias for more formal things. I was able to add my casual account to my Accounts on my Lumia. However I'm not able to add my alias. The domain of it is different but the servers they use are same. I get my emails from both of my addresses because I set formal one to forward it to the other, but I can only send with the casual one. Do you know how can I also send emails form my formal address?
