since you switched my hotmail account to an Outlook account (i think in august)
i have not been able to do the following:

access any of my 10+ years of accumulated contacts in address book.  my contact list is now empty
even when i click to "add email to contact list" the system does not do it
I can not attach documents to any of my emails sent via any one of my three hotmail accounts.  i get a drop down message that says "We're still setting this up"

This is causing huge issues for me!  dont know why you fiddled with hotmail.  it was fine the way it was.
