Compliance Features For Advisors In Microsoft Office 365

I am unclear if this applies to E3 subscriptions. If so, the screenshots do not match what I see when I try to duplicate. Perhaps a 'hands-on', very slow class would help. For instance, a retention policy screen requires me to type in the URL but I do not know which ones. My main login is not an acceptable choice. Loved the webinar but I need to review it slowly and have more information.
