Step 1: Register an EnvironmentFollow
Each environment must be created with a global admin of the corresponding Office 365 tenant. Make sure this account has a mailbox enabled. During registration, workspace sends a confirmation e-mail to that account. For more info on how to register an environment, contact your Workspace 365 Administrator or Submit a request.
After you've received the e-mail, make sure you navigate to the URL listed in the email. Log in with the credentials that are provided to you in the e-mail.
After you have logged in, you will be prompted to set up Single Sign-On.
