REF: E14 Outlook Provider
Exchange 2010 Set-OutlookProvider http://technet.microsoft.com/en-us/library/bb123683.aspx The Set-OutlookProvider cmdlet creates the global settings for the Autodiscover service. It sets the AutoDiscoverConfig object under the Global Settings object in Active Directory and sets the attributes specified in the parameters listed in the Parameters section. The Autodiscover Service and Outlook Providers - how does this stuff work? http://blogs.technet.com/b/exchange/archive/2008/09/26/3406344.aspx By default three Outlook Providers are used to configure settings individually for Exchange RPC protocol or internal clients ( EXCH ), Outlook Anywhere ( EXPR ) and WEB . The EXCH setting references the Exchange RPC protocol that is used internally. This setting includes port settings and the internal URLs for the Exchange services that you have enabled. The EXPR setting references the Exchange HTTP protocol that is used by Outlook Anywhere. T
