How To Create an Autodiscover Record

More tidying up of the Question and Answer section, yes a lot of these are very simple but still useful for some people so today back to the basics of Exchange. A reader asked what was and how to create and Autodiscover record for Exchange.

Additionally when connecting your Outlook client to Microsoft Exchange for the first time it will setup Outlook for you. An A record or CName is created called Autodiscover, this points to the IP address of your CAS server ( Exchange 2007, 2010 and 2013). If you are authenticated then the mail client will will then be directed by the CAS server to the Mailbox server your mailbox is hosted on.
