I currently use icloud for our contacts and calendars.  I was considering using outlook.com for this instead.  Is there a way that two separate outlook.com acconts can share a calendar and contacts.  For example, if I add a contact on my iphone I want it to get pushed through to outlook.com and my wifes phone.  Also when information is added to outlook.com through outlook 2007 I'd like it to go to both phones.
