Windows 2003/ Active directory and Exchange 2003

Hi, I have to automatically create Active directory users via .net.

I have successfully created users, added them to the relevant groups etc but now I have to create their mailboxes.

How do I go about doing this is VB.net?? From searching around the net it looks like I have to use CDOEXM.... Is there a better way?

Thanks in advance

Check out MIIS from microsoft. This syncs your datastores. Not sure about price, but might be a good option.
