The administration and maintenance of Microsoft Exchange Server to ensure secure, reliable, and efficient email and collaboration services across an organization.
For an Exchange Server 2019 certificate renewal from a third-party CA, create the certificate request on the Exchange server, then submit that request to GoDaddy.
A certificate that was originally created from an Exchange certificate request should be renewed by:
- Creating a new certificate request in Exchange.
- Sending that request to the CA.
- Completing the pending certificate request after the CA returns the certificate.
- Assigning the certificate to Exchange services.
Exchange documentation states that New-ExchangeCertificate is used to create certificate requests for new certificates and certificate renewals from a certification authority. The certificate request workflow is also the documented process for configuring a third-party SSL certificate on Exchange.
If using Exchange Server 2019:
- EAC certificate management is available in Exchange 2019 CU15 and later.
- For Exchange 2019 CU12 to CU14, use the Exchange Management Shell.
After the CA returns the certificate, complete the pending request on the Exchange server, then assign it to services. At minimum, assign it to SMTP and IIS. If prompted to overwrite the existing default SMTP certificate, select Yes.
To verify the renewal worked in EAC:
- Go to Servers > Certificates.
- Select the new certificate.
- Confirm Status is Valid.
- Confirm Assigned to services includes at least IIS and SMTP.
