How am I suppose to access my contacts list? When i type in a name nothing appears.

I have tried to update the names/email addresses listed in groups; however, while I can see them when I click on people and group name, when it comes time to send an email to them, it gives me two of the same addressees and leaves one off. 

 

Under manage groups, it tells me that I an delete the name of the group, but the names still stay listed.  Why would I want to delete the group name and not the group itself.  I can click/apply all kinds of things listed, but it doesn't work when I go to do email. 

 

The more  I work with this new set up, the worse it gets.  I want to know simply how do I delete groups? 

When I bring up my forwarding option in hotmail an unknown name appears. This name does NOT appear in my CONTACTS listing only when I bring up a request to forward a message. How did it get there and more importantly, how can I delete it?

I have just read the changes to the Microsoft Services Agreement.  I only have a Hotmail account and occasionally use Bing.  Does this mean I have a services agreement?  I don't recall signing anything when I originally signed up for Hotmail.  Is my user name and password for Hotmail the user name and password for Microsoft?  I appreciate any input.  Thank you.
When I want to forword a msg and click the 'To:' box, my list of contacts is displayed,but there is now a name on the list that I don't know. When I go to my Contact list that unkown name isn't there for me to delete. It's only on my forwoarding contact list. how do i remove it?
I was just contacted by a friend who says she got an link sent to her by someone using my Name but not with my email address. She contacted me to see if any other friends of mine had received this email or if I had given her email out to this person. Does this mean someone could have hacked into my email account and gotten my list of contacts? The email address they used to contact her with was a Yahoo address.
I went to People site, clicked on "new" and entered a new contact.and the contact's email address. Clicked on "save". Returned to inbox and attempted to forward an email to that contact, but name did not appear in contact list. I tried several times with no success. How do I add a contact to my list?
How can I print out my hotmail contact list with full e-mail address, as well as associated name? 
I windows outlook, when you begin to type the name or the email address you have used before, outlook would suggest email addresses.
does anyone know why outlook for mac does not do the same?
please help me
