Now we can go into the release OWA process. You first need to generate a new trusted certificate for Exchange Server, unlike Exchange 2007, where Exchange 2010 's certificate request files are done in EMC, not in IIS.
Turn on EMC, navigate to the Server configuration node, and in an intermediate result set, see a certificate from the Exchange Server itself that is an untrusted certificate issued by Exchange Server to itself. We need to reapply a certificate to a certification authority within the enterprise. Here's a reminder that you don't want to delete the original certificate. Here we will use EMC to complete the creation of the certificate request file. As shown in Figure 1.

Click New Exchange Certificate on the location shown in Figure 2 to open the New Certificate Wizard. Follow the steps in the wizard prompts, especially to remind you that in the interface shown in Figure 2, do not check "enable wildcard characters", click "Next" and manually specify the parameters for each service.
