How to Access Distribution Lists in Contacts Folder on Exchange Server?

Hi,

I am connecting to Mailbox of a user on Exchange Server 2003 using CDO 1.2.1 in VB.NET 2005.
I have created "Contact1" & "Contact2" folder under "Contact" folder on Exchnage server.

I have created Distribution Lists in all above 3 folders on Exchange server and also added few contacts in those Distribution lists.

But, I'm not able to access a particular Distribution List in any of the above folder. I'm also not able to access contacts/members in any of the above contact folder.

How to get following things, using CDO 1.2.1 in VB.NET 2005 :
1) contacts/ members in "contacts" folder
2) The list of existing Distribution Lists in contacts folder.
3) The list of existing members/users in above Distribution List.

Is there any way to get above things?
Please, specify if you are using higher version of CDO or if you are using Redemption or any other objects instead of CDO.

Thanks for the help in an advance.
Waiting for the reply desperately.

Moved to VB.NET

These folders you created, were they created manually or by code? Did you set the permissions on them too? CDO 1.21 is that last version and AFAIK its not being developered anymore.
