Disappearing Outlook Express Spam Button

My Norton 360 has just been "improved".  Yet again the Spam function for Outlook Express has disappeared.  However this time the Norton experts (Removed) cannot think of a solution.  I'm told "we only support Outlook" and "some people are upgrading" to this.  When I asked if this was a final decision by Norton to no longer support XP/Outlook Express users and will Norton then include Thunderbird in their Client Integration, the support chat was terminated without an answer.

This is worrying Customer Service and I have used Norton products since the early IBM PC days.  Does anyone know of another security product with a Norton like identity safe?
