Deleting a group in Hotmail (not in messenger) , I go to edit the group and delete. Group is not removed.

Removing a name from a group, by clicking off in the categories, does not remove the name.

I attempted to move an email from my inbox to a subfolder but it failed to move and seems stuck in the inbox. Deleting it from the inbox does not work. Tried to do this whilst in offline mode and still no joy. Appreciate some help here.
If you start writing an email to send but have to stop half way for some reason it gets saves as a draft which you can go back to later. My draft folder keeps adding new drafts which I haven't started. It happens a couple of times a day. Deleting them gets rid of them but does not stop new drafts appearing. It happens even if I don't go into the drafts folder.
