Contact format was changed in Hotmail recently.  I'm having trouble getting new ones entered.  After hitting 'apply' they are then not coming up when trying to send and email.  Also one I put in wrong, went in and deleted it and put in the new one, but the old one keeps coming up still.  It won't let me put the new one in.  The emails are showing in the contacts section but not when I try to do an email.  Why.... Help...

I want to send an email to several Groups of people that I have put together in the 'People' area.  I go into Hotmail, press 'New', press 'To', select 'Categories' and, in the past, the Group names have appeared in the 'Categories' section for me to select.  At present, none on the Group names that I have created in the 'People' area appear in the 'Categories' section of a new email.  How do I put a newly created Group of people into the 'Categories' section which I can then select so that the Group name appears in the 'To' box on a new email that I want to send out?

I just hit the button that say: "New Calendar" by mistake.  It created a new "On My Computer" calender, even though one already exists.  How can I delete it.  Since it was that easy to create.  I should be that easy to delete, but I can't find a way to delete it anywhere.
I'm trying to add a completely new group into my Hotmail.  When I add the new group in People, it doesn't even show the new group name when I try to send an email.  In People, I have the option of sending an email to the group, but that puts everyone in the TO:  I want to BC: them.  This use to be so simple!

I AM OLDER GENT BEFORE I DO ANYTHING I WOULD LIKE TO KNOW WHAT THE DIFFERENCE IS BETWEEN BOTH. AND ALSO IS   OUTLOOK.COM THE NEW (AT SOME POINT) THE NEW ONE TO BOTH

RESPECTFULLY

I  am trying to create a new group under contacts. I followed the advice from Kathleen Collins: I went to the People window, to the toolbar at top, clocked on Manage, then on Manage groups. I was getting excited because so far, so good. After that , no plus+ sign appeared or rather, there is a + sign in a circle at the top (just to the left of "New", but it is greyed out and won't allow me to click on it. Maybe this is not the correct + sign anyway. What is wrong?  I use Firefox, maybe I need to use Explorer in order to do this? Thanks for any advice you can give. Now frustrated and getting desperate.
