I have installed exchange server 2013 in a child domain child.domain.com. The parent domain (domain.com) has a wildcard certificate used for their exchange server. <br />

Can I use this certificate on my child domain for both the Backend Exchange on port 444 and front end on port 443? <br />
<br />
Why I am considering this is because outlook is poping up certificate for client.
