Assign a certificate to the UM and UM Call Router services in Exchange Server

Applies to: Exchange Server 2013, Exchange Server 2016

You can use the EAC or the Shell to assign a self-signed, internal public key infrastructure (PKI), or third-party commercial certificate for specific Exchange services. When you use the New-ExchangeCertificate cmdlet to assign the certificate to Exchange services with the Services parameter, you're prompted to assign the certificate to Exchange services. If you use the EAC to create a certificate, the New Exchange Certificate wizard won't prompt you to assign the certificate to Exchange services. You need to edit the properties of the certificate and assign the certificate by selecting which services you want to assign it to.

Different services have different certificate requirements. For example, some services may only require a server name in the Subject Name or Subject Alternative Name boxes of a certificate and other services may require a fully qualified domain name (FQDN). Make sure that the certificate name can support the uses required by the services you enable it for.

Warning

Self-signed certificates can't be used when you're integrating Unified Messaging (UM) with Microsoft Lync Server.

For additional management tasks related to managing certificates for Unified Messaging, see Deploying certificates for UM procedures.
