I found this code online just to create an outlook calendar folder. The following code is throwing an error saying that the host name cannot be resolved. Not sure where to go from here. I konw what my exchange server address is, but can't get it to connect. Any suggestions?

 First make sure you have configured you exchange to allow web mail, then make sure the account you are logging as have read permissions to the mail box you are trying to access.
