I have created a new externally signed certificate for our Hybrid Exchange server. It has been enabled for both IIS and SMTP, and we have restarted the server twice. The new certificate shows up as being enabled for SMTP.
However, when we are trying to run the commands to replace the send-connector certificate, as seen in image, we get the error:
The given certificate is not enabled for SMTP protocol. Only certificates enabled for SMTP protocol can be set on Send
Connectors. To enable a certificate for SMTP, please use 'Enable-ExchangeCertificate' cmdlet.
The certificate definitely appears to be enabled for SMTP, and we have restarted the server twice since this. Could anyone please suggest to me why this error would still appear?
For added context, this is the only Exchange Hybrid server in our environment. And all commands are being run from it.
