Signing into my Hotmail.com account that is now under Outlook, approximately 11:30-11:45 a.m. DST 1/2/13.

 I tried to send an e-mail with attachment to a regular business account and my entire address book was NOT available to me. I tried thru Outlook to see or recover the data to no avail.

 What is the problem, has my account been hacked?

 How can and how do I remedy this?

 This is the FIRST time I have ever had this problem since setting up my Hotmail account in 2000. When Outlook took over these accounts, there have been problems!

I live in USA - Virginia
