From the Exchange server console I ran this: [PS] C:\Windows\System32>Get-OutlookProvider Name Server CertPrincipalName TTL ---- ------ ----------------- --- EXCH 1 EXPR exch-01 msstd:webmail.my... 1 WEB 1 Should the EXPR Server be set to my external webserver url? Should the others be blank as shown?

Hello, Based on what you ar trying to achieve, you could use the Set-OutlookProvider cmdlet to achieve it. For a very good post on this topic, including various scenarios that you might find helpful, please check :http://msexchangeteam.com/archive/2008/09/29/449921.aspx Hope it helps, Mihai

Hi- The others should be blank and the Server is fine. If you want to tweak the URLs, you want to use the Set-OutlookAnywhere cmdlet. Make sure the cert principalname in your output matches the common name on the cert securing the CAS servers.Active Directory, 4th Edition - www.briandesmond.com/ad4/

Hi, You have to check the Auto-Discover InternalURI is pointed to the CAS for autodiscovery servicing. Get-ClientAccessServer -Identity CASServer | FL Since the Autodiscover directory in IIS require SSL encryption, the url specified in the, AutoDiscoverServiceInternalURI must match what is specified in your certificate. You must also ensure there is a DNS record that allows the client to auto-discover and resolve the CAS Please try this following cmd to add Auto-Discover URL Set-ClientAccessServer -Identity CASServer -AutoDiscoverServiceInternalUri https://mail.domain.com/Autodiscover/Autodiscover.xml Thanks Mhussain
