User Profiles are stored in a SharePoint list called CT User Profile. Profiles are either Managed or Personal.

Managed profiles

Where profiles are updated and managed by the CT365 Management Solution.
This requires SharePoint API Approval for setup in the Management > Profiles tab. The update schedule is set in the Management > Flows tab.

Personal profile

Where profiles are updated by the individual.
Personal terms can be added from the Read Profile page. This option requires the User Profile list permissions to allow individuals to create and update their own entries.

User Profiles support multiple term associations per person in each site. Where terms are shared across multiple sites, the User Profiles list is only created in the main parent site.
