You are testing the planned implementation of Exchange Server 2013.
After you begin moving several mailboxes to Exchange Server 2013, you discover that users on the internal network that have been moved are prompted repeatedly for their credentials when they run Microsoft Outlook.
You run the Get-OutlookAnywhere cmdlet on CH-EX4, and receive the following output:
You need to prevent the internal users from being prompted for their credentials when they connect to their mailbox by using Outlook.
Which property should you modify by using the Set-OutlookAnywhere cmdlet?
A. IISAuthenticationMethods
B. InternalHostname
C. ExternalHostname
D. ExternalClientAuthenticationMethod
E. InternalClientAuthenticationMethod
Correct Answer: A
Explanation/Reference:
Explanation:
InternalClientAuthenticationMethod is NTLM
Windows Challenge/Response (NTLM) is the authentication protocol used on networks that include systems running the Windows operating system and on stand-alone systems.
NTLM credentials are based on data obtained during the interactive logon process and consist of a domain name, a user name, and a one-way hash of the user’s password.
NEED TO CONVERT THE INTERNALCLIENTAUTHENTICATIONMETHOD TO BASIS NOT NTLM IN ORDER TO FIX THE ISSUE.
USE IISAUTHENTICATIONMETHODS PARAMETER IN ORDER TO ACHIEVE THIS.
Set-OutlookAnywhere
Use the Set-OutlookAnywhere cmdlet to modify the properties on a computer running Microsoft Exchange Server 2013 enabled for Microsoft Outlook Anywhere.
EXAMPLE 1
This example sets the client authentication method to NTLM for the /rpc virtual directory on the Client Access server CAS01.
Set-OutlookAnywhere -Identity:CAS01rpc (Default Web Site) -ExternalClientAuthenticationMethod:Ntlm
PARAMETERS
The IISAuthenticationMethods parameter specifies the authentication method enabled on the /rpc virtual directory in Internet Information Services (IIS).
You can set the virtual directory to allow Basic authentication or NTLM authentication.
Alternatively, you can also set the virtual directory to allow both Basic and NTLM authentication. All other authentication methods are disabled.
You may want to enable both Basic and NTLM authentication if you’re using the IIS virtual directory with multiple applications that require different authentication methods.
The InternalHostname parameter specifies the internal hostname for the Outlook Anywhere virtual directory.
The ExternalHostname parameter specifies the external host name to use in the Microsoft Outlook profiles for users enabled for Outlook Anywhere.
The ExternalClientAuthenticationMethod parameter specifies the authentication method used for external client authentication. Possible values include:
Basic
Digest
Ntlm
Fba
WindowsIntegrated
LiveIdFba
LiveIdBasic
LiveIdNegotiate
WSSecurity
Certificate
NegoEx
OAuth
Adfs
Kerberos
Negotiate
