i have acquired a new public certificate for my exchange server as its existing certificate will expire soon.
the certificate was requested and the details of the certificate read as it should and matches most of the fields of the existing certificate.
when trying to import the new certificate using the import-exchangecertificate command i get the following error message -
cannot import as there already is a certificate with a thumbprint of xxx.
so i tried removing the certificate using the remove-exchangecertificate -thumbprint command and received the following -
the certificate with thumbprint xxx was found but is not valid for use with exchange server <reason:privatekeymissing>
any assistance would be appreciated.
