I have a SBS2011 and start to get this message of "There is no valid SMTP TLS certificate for the FQDN of exchange.whatever.com. The existing cert has expired..."
I read through some posts as to run commands on Exchange but no clue as to where and how to , the IT guy left so I am a bit stuck, could someone give a a simple walkthrough ?
I get this is the cmdlet needed but are there any parameters I need to change to reflect my own server ?
