可以使用asp.net c＃application自动创建Exchange 2003邮箱吗？

I wrote a asp.net C# website that creates users in active directory but I would also like to automate the mailbox creation as well. The exchange server is 2003 and I would need to automate creating the mailbox, the store the mailbox is located in, and the mailbox quota policy for that user. Does anyone know if this is possible or does the exchange server have to be 2007/2010? If it is possible could you point me in the right direction? Thanks a lot!I wrote a asp.net C# website that creates users
