We are using a portal software (Luminis Platform IV) right now and are moving it to authenticate against Active Directory. I created the code to authenticate users, provision accounts in AD, and sync related data overnight. Most users will be created in the portal software by our portal support staff, and AD is used only for authentication with other systems on campus.
We are now setting up an Exchange 2007 system as our primary email server. Could somebody please help me or provide the code to find users in AD that do not yet have a mailbox, and create an Exchange mailbox for them?
