lug-ms you should run HCW version 17.x (newest) and let the agent do the job. Certificate replacement requires to re-run HCW and this should then work without any problem.

      lug-ms are there other certificates bound to the SMTP service? If you run Get-ExchangeCertificate you should see all thumbprints and services (S stands for SMTP).

        Yes, the federation certificate is bound to SMTP, which probably automatically happened when removing the old certificate from the server.

        You can see more details about the federation cert in my starting post 😉
