OWA (Exchange 2013) with ADFS

Hi,

I've been trying to connect between our OWA (Exchange 2013) to our ADFS server according to this guide - https://eu.netdocuments.com/neWeb2/docCent.aspx?whr=CA-ISRRR0MN

I've reached one of the last steps (enable ADFS authentication on the OWA and ECP) but I got an error now - when trying to run the command

Get-EcpVirtualDirectory | Set-EcpVirtualDirectory -AdfsAuthentication $true -BasicAuthentication $false -DigestAuthentication $false -FormsAuthentication $false -LiveIdAuthentication $false -WindowsAuthentication $false

I get an error - a parameter cannot be found that matches parameter name "LiveIdAuthentication".
Any thoughts?

If I just remove the "LiveIdAuthentication" parameter from the command it works ok, but then I move forward to OWA configuration (same command but without the "LiveIdAuthentication" parameter). Then I get and error regarding "ADFSAuthentication"...

Thanks for helping...
