I am not a big fan of Outlook, I prefer Gmail, but it does have some nice features and in a corporate environment you almost never have another choice.

One of the nice features of Outlook is the ability to color code your messages.  For example you can color code the subject line to highlight messages addressed directly to you via:

Tools > Organize >  Using Colors > Messages sent only to me now appear [Blue] > Turn On

There are other filters you can turn on by clicking on “Automatic Formatting…” at the top right in the Tools > Organize > Using Colors window.
