I Called Msn Customer Service Around 7 This Morning And Spoke With Someone Who

I  called MSN customer service around 7 this morning and spoke with someone who  identified himself as Brian. Brian could not help me with my problem. The problem is as follows: I typed in my name in google and on the google web page - www.google.co.uk  I was able to view all of the messages that I had sent  via my windows live hotmail over the last several months. I am very,very upset since many of the messages are sensitive.  Brian says that this is not an MSN issue, it is a google issue. I pay MSN monthly, not google. How can this information be taken off  of the google site and does this mean that MSN mail is not secure? If so, I have no recourse but  to cancel my MSN account immediately. I need your feedback asap. Thanks.
