This is a second shock after ServerManagerCMD for me. I don’t know why they changed it but there is no -Path switch anymore. We have to use Set-Content instead of -Path switch. When I use -Path switch with New-ExchangeCertificate, I get this error:

Generating CSR request in Microsoft Exchange Server 2007 with Powershell:

New-ExchangeCertificate -GenerateRequest -Path c:\Exchange.csr -KeySize 2048
-SubjectName "c=TR, s=Metrocity, l=Istanbul, o=Radore Hosting, ou=IT, cn=exchange.radore.net"

Generating CSR request in Microsoft Exchange Server 2010 with Powershell:

$CSR = New-ExchangeCertificate -GenerateRequest -KeySize 2048
-SubjectName "c=TR, s=Metrocity, l=Istanbul, o=Radore Hosting, ou=IT, cn=exchange.radore.net"
Set-Content -path "C:\Exchange.csr" -Value $CSR

Using a second command shouldn’t be necessery. I don’t know why they add Set-Content for this action.
