setup newsgroup problem

[Qnguyen]

I have to trouble outlook newsgroup as follow:

I tried to set up newsgroup in MS Outlook. I followed the instruction in
outlook help. Go to toolbar option, then add remove button select customize.
select "Go" in categorie and choose "news" command to drag it to the tool bar
inside Go menu. I continued to set up the newsgroup but latter I went back
to Go Menu in outlook to search for the news. Unfortuately, it disappeared
and also news command in Go category also disappeared. How can I run the
newsgroup with no link to it. How can I make it appear again on Go menu.
Thanks
