Check out two helpful features of MS Office Outlook 2010 (both the 32 bit AND 64 bit installs);
Topic - Conversation View (assume this is set)
1) Ignore Conversation, say you have only been CC'd into a thread of a conversation and you feel it hase no interest for you any longer, RIGHT click on message (in Inbox with Conversation View set) select Ignore Conv & confirm the pop up dialog, Viola!
2) Clean up Conversation, cleans up very long emails bounced hither and fro, only leaving the relevant one - check the you tube for how easy it is.
