disgruntled

I, among many, do not like the changes from hotmail to outlook.  My big problem is that I lost all of my groups for email.  They are still there, but I cannot add anyone else to the group.  Also, when people change email addresses, the old one stays in, so I get the rejected email and sometimes it won't even bring up the new address.  I have to go searching and sometimes it won't come up.  It's in the address book, but I can't send an email unless I do it individually.  There is an "upgrade" button, but nothing happens when I click on it.  Come on folks!  I signed up for gmail, but I can't do groups there either.  I like hotmail and want to stay there.  Help?
