certificate issues RRS feed

  • Question

  • I am trying to remove a self-signed certificate so we can be certain we are only using the one we got from a trusted 3rd-party CA.  When I try to remove the self-signed one, I get this error below.

    A special Rpc error occurs on server MAIL14: The internal transport certificate cannot be removed because that would
    cause the Microsoft Exchange Transport service to stop. To replace the internal transport certificate, create a new
    certificate. The new certificate will automatically become the internal transport certificate. You can then remove the
    existing certificate.

    But if I create a new self-signed certificate, just to remove the old one, then I am not getting anywhere - is there any way to change the "internal transport certificate" to use the one we got from the 3rd-party CA?  I already have the new certificate installed and I would rather not try to go through the process of generating a new cert request and all that.  But if that is the only way to fix these issues, then I suppose that is what I must do.

    Many thanks,

    Sam
