Let’s get started!
Renew a Certificate with Exchange Admin Center
Log into the Exchange Admin Center (EAC). Select the Servers tab and Certificates sub tab.
This page displays all currently installed Exchange certificates. In our example we see four self-signed certificates. We also see our certificate that we acquired from a trusted certificate authority. This certificate is named webmail.exchangeservergeek.com. This is the certificate we will be renewing.
Select the certificate to be renewed (in our case webmail.exchangeservergeek.com) and click the Renew link in the task pane to the right.
The renewal process will create a new certificate request to submit to our certificate authority. Specify a location to save this certificate request. This location must be in the form of a UNC path. In our example we specify a file called certreq.txt at the path \\ex16-01\c$\users\supertekboy\desktop\. This will create a text file on our server’s desktop. Click Ok.
