You can forward your Angel mail, but only to your Kirkwood e-mail account. You are NOT able to reply directly to Angel messages even from your Kirkwood account, but you can see and read them.
Kirkwood Community College’s IT department gives these instructions:
You may choose to forward your ANGEL mail to your Kirkwood email address only. Please note that you cannot reply to ANGEL email outside of the ANGEL system. There are two ways to forward your ANGEL mail: Through your personal preferences or through your inbox. This tutorial will show you both methods. (Current as of Aug. 21, 2013)
