I am trying to set up AD FS authentication with the owa virtual directory while following this TechNet article:

http://technet.microsoft.com/en-us/library/dn635116(v=exchg.150).aspx#party

I have successfully gotten the ECP virtual directory to authenticate against the AD FS & AD howecver when I try to configure the OWA virtual directory I receive an error message while setting the field to true:

[PS] C:\Windows\system32>Get-OwaVirtualDirectory | fl AdfsAuthentication


AdfsAuthentication : False



[PS] C:\Windows\system32>Set-OwaVirtualDirectory -AdfsAuthentication $true
A parameter cannot be found that matches parameter name 'AdfsAuthentication'.
    + CategoryInfo          : InvalidArgument: (:) [Set-OwaVirtualDirectory], ParameterBindingException
    + FullyQualifiedErrorId : NamedParameterNotFound,Set-OwaVirtualDirectory
    + PSComputerName        : adfs.vaultiveps.com

[PS] C:\Windows\system32>

I have used the full command mentioned in the technet article but I received same results....

Is there a workaround to get OWA to authenticate against AD FS?

I don't see where you specified the OWA virtual directory to which you want that property applied.  Perhaps you need to specify that.

Hi Ed,

Two points, I followed the same process for the ECP directory which worked fine however, I am unable to reference the Adfsauthentication property of the OWA directory. I have also tried specifying the identity which resulted in the same error messages. 

For reference:

[PS] C:\Windows\system32>Set-OwaVirtualDirectory
Creating a new session for implicit remoting of "Set-OwaVirtualDirectory" command...

cmdlet Set-OwaVirtualDirectory at command pipeline position 1
Supply values for the following parameters:

Are you running SP1?

Hi Psychephylax,

According to the following information from Technet article, I notice that you have to configure the AdfsAuthentication Parameter of ECP VD value to True before configuring OWA VD.

The ADFS authentication settings for Set-OwaVirtualDirectory and Set-EcpVirtualDirectory are related. You need to set the AdfsAuthentication parameter on Set-EcpVirtualDirectory to $true before you can set the AdfsAuthentication parameter on Set-OwaVirtualDirectory to $true. Likewise, you need to set the AdfsAuthentication parameter on Set-OwaVirtualDirectory to $false before you can set the AdfsAuthentication parameter on Set-EcpVirtualDirectory to $false.

More details to see: http://technet.microsoft.com/en-us/library/bb123515(v=exchg.150).aspx

 

Thanks

Hello,

I follow all step required by Exchange and ADFS configuration. download some script to avoid any syntax problem.

But i have the same issue 

[PS] C:\Windows\system32>Set-OwaVirtualDirectory -AdfsAuthentication $true
A parameter cannot be found that matches parameter name 'AdfsAuthentication'.
    + CategoryInfo          : InvalidArgument: (:) [Set-OwaVirtualDirectory], ParameterBindingException
    + FullyQualifiedErrorId : NamedParameterNotFound,Set-OwaVirtualDirectory
    + PSComputerName        : adfs.vaultiveps.com

I runned set-ecpVirtualDirectory -adfsauthentication $true fine, but for OWA it's not working.

Any solution will be welcome.
