Change me.com SMTP server to outlook.com

I use the iCloud Mail to manage my emails on my Mac and iPhone. But my primary email is with outlook.com. For receiving the emails I have simply forwarded my outlook.com emails to me.com. Now the problem is when I send the emails it goes from me.com address. Is there a way I can change my outgoing address to outlook.com in iCloud Mail client on iPhone and iCloud.com?

Thanks in advance.
