We have recently come across a situation where we need to start ensuring that specific emails that are sent within our company are secure. Not all emails need to be 'locked down' in this respect but if someone wants to send something HR related then they may want to 'encrypt' or secure it in some fashion. I read that you can use outlook to do this free? I am not an exchange 2010 guru so i need to know what my basic options are and if there are any options can i get a step by step to enable this or something i can pass onto our users so if they have a sensitive attachment they can send internally with a little less worry.
We have one exchange server in our organization running Exchange server 2010. Any help is appreciated.
