Do you like the way that your mobile iPhone, or Gmail groups messages into a conversation thread?
If so you can do this in Outlook 2010 helping to keep track of what’s been discussed by email.
Simply select the View tab and check the Show as Conversations box on the top left.
Outlook will then ask if you want to activate conversation view in only this folder or all folders. Choose All folders to view all emails in Outlook in conversations.
Viola! Your emails will be now threaded making it easier to track back on your e-correspondence.
