I have a new BB Storm. I hired our company's 'outside IT" person to place the "free version of BES for one user" on our company server. Obviously, none of the others at my company have a BB

. This IT person has set everything up for me. He cost me per hour, and I cannot afford much more of his help, so I am doing most of the research now on crackberry to get questions answered.
Bit more background: We have email for the company, with a company directory, so that when I am at work, it allows me to quickly access employees and other owners' internal addresses. I also have an outside email from Comcast, which is set up on my BB with BIS.
Problem: with my old Samsung phone, when composing a new email, I had the option of either using my contact list (personal list that I maintain with email addresses, phone numbers, etc) or else I could click on "Company Directory" and it would let me search there for email addresses. With my new BB Storm, when composing a new email, I don't see an option like that. If I start typing an email address, it looks in
my contacts folder for a match. Since I don't keep the list of all company people in my directory, this is inconvenient for me to send emails.
How can I access the Company Directory? What is the SIMPLEST way to set this up, or will I have to have the IT guy, who has access to our server, do so?
Thanks so much,
