I have a home lab setup which is helping me learn exchange server 2013

I have installed server 2013 and it is operating as expected.

When I try to access outlook anywhere from a client machine I get a certificate error.

Through investigation I understand that I need to upload a certificate to the client machine.

I cannot seem to find any definitive instructions on how I can achieve this.

I would imagine I can create the certificate through the EAC and then import this to the client machine

I do not know however what to include in this certificate

Can someone help?
