Microsoft has changed the name of Delve Analytics to MyAnalytics.
This change is related to the end users that have many questions about who see this information.
To clarify this feature that now called MyAnalytcs is only seen by the person who see the information not anyone else on the organization and only shows the documents that are shared to that person. Neither the Tenant Admin have access to that information.
Microsoft has released a new version of this feature that included the availability of external contacts within your MyAnalytics experience. Now you will be able to stay up to date on how you interact with important contacts outside of your organization.
