If you wanted to email a new guy in your company, you know that he should be found in Exchange’s Global Address List, If you haven’t emailed him before, and Outlook’s auto-suggest name list doesn’t appear to recognise the name (you know the one that pops up as you start typing in the “To” field), you can just start typing then press the Ctrl + K.
