Creating a CSR on Exchange 2007

In order to create a CSR on Exchange 2007, you must use the New-ExchangeCertificate cmdlet.

The 'GenerateRequest' parameter for this cmdlet will create the CSR, as a PKCS#10 file which we will then use to create your certificate.

The 'SubjectName' parameter contains the details that are signed into the certificate. The 'CN' parameter is the PrimaryDomainName, and should also be entered into the order form.

An example command to generate a request would be:

New-ExchangeCertificate -GenerateRequest -SubjectName "C=GB, O=Comodo, CN=exchange.comodo.com" -IncludeAcceptedDomains exchange.comodo.com, server1.comodo.local, server1 -Path c:\exchange.comodo.com.req

The resulting 'exchange.comodo.com.req' file can be opened in Notepad or similar text-editor and pasted into the order form.

Note: If you plan on exporting your certificate from your server or making a backup of this you will need to use the below command to enable this

New-ExchangeCertificate -GenerateRequest -SubjectName "C=GB, O=Comodo, CN=exchange.comodo.com" -IncludeAcceptedDomains exchange.comodo.com, server1.comodo.local, server1 -Path c:\exchange.comodo.com.req -PrivateKeyExportable $true
