Links for Programming Exchange and ADSI

One of the projects I am working on is to automate some tasks in Exchange, such as converting people from being Mail enabled to Mailbox enabled. As well as adding altRecipients programatically. These are some of the links I have been reading, not all of them are directly useful to this project. I will post some sample code later on different things I had to work around to modify Exchange objects via ADSI.
