We are utilizing Office 365 and I have a user who took on an additional role. Her email is *** Email address is removed for privacy ***, due to the new roll she is worried people will be confused and wants to send an email through outlook for mac 2011 as the alias, *** Email address is removed for privacy ***.

I have done some research on this and attempted it, however, I cannot seem to add the alias as an email address. Does anyone have an insight to how this could be done?
