When you want to keep track of a project -- like who you communicated with, and what you talked about & decided -- but not all of your transactions on the project are email messages, you can use Outlook's Journal funtion to collect the info in one place. The Journal is an often-overlook feature of Outlook. It can create a timeline of transactions (phone calls, conversations, meetings, etc.) that can be linked to one of your contacts.
