Having appointments outside the office? Want to block the time to get to the location in your Outlook calendar? If so, this add-in is going to be a huge help. It allows you to create "travel" and "return" appointments right before and after the outside appointment. These appointments are linked to the main appointment, so deleting / moving or changing the main appointment will keep the travel appointments at the correct position.
