This article will help you export a certificate from Exchange 2013 and above versions and import to other servers.
When planning for an Exchange server implementation, we may choose the same certificate to install in other servers. The method of getting a certificate for single or multiple servers are the same. Create a CSR easily using the
tool and use your FQDN (Fully Qualified Domain Name) for the CAS server namespace. e.g.mail.domain.com, webmail.domain.com. Exchange server does not require internal FQDN(server names) in the certificate.
Once the CSR is completed as per the
article/tool on the 1st server you can export the certificate to PFX and import the same certificate on other servers using the following steps.
Export from the current server.
Navigate to
Server-->Certificate in Exchange Admin Center
