Creating Certificate Signing Request in Outlook - Office 365 Home Version RRS feed

  • Question

  • Hello

    I have bought an SSL Certificate from an external provider and I want to use this certificate to encrypt emails in Office 365 (Outlook). My version of Office is the Home, not business, edition.  I need to create a CSR (Certificate Signing Request) to obtain the certificate from my external provider and import it to Outlook.  How do I create a CSR in Outlook?  I can't seem to find any instructions on how to do this.  I phoned Microsoft support and the advisor didn't know either. 

    Thank you.

  • Hell Beth-Anne,

    Which kind of certificate have you actually bought?
    To encrypt/sign mail traffic you need to use a client certificate for S/MIME in which your e-mail address is specified in the UserDN attribute.

    From ypur description I assume you have bought a web server certificate in this case?

    Best regards,
