If you're like me, when creating a meeting, you hate trying to remember each conference room's name, selelcting it in Outlook, and then trying to figure out a time and room for the meeting. Most of the time, I'm sure I'm forgetting a room. Of course, if the names of the rooms all started the same (eg, Conference Room - Manhattan), it would be easier.
So, I created a distribution list for conference rooms in my local contacts list. Just click on New->Distribution list, and then add each conference room to the list. This will be the only time that you have to remember and find each conference room's name. From here on out, you can just use the list.
