Please note that you will need to have installed the Egress Client for Mac already.
If you have received an encrypted email, click the attached '.switch' file to open it. You will be prompted to sign in with your Egress ID and password.
If you have not already created an account, you can do so via the Client by clicking 'Don't have an account?'.
Once you have signed in, you will be able to access the secure package.
