In the %BRAND_OFFICE_365_SHORT% cloud. You can manage %BRAND_OFFICE_365_SHORT% users in the %BRAND_OFFICE_365_SHORT% cloud directory service called %BRAND_AZURE_ACTIVE_DIRECTORY%. You'll manage these %BRAND_OFFICE_365_SHORT% user accounts over the Internet with the %BRAND_OFFICE_365_SHORT% admin center. Users who are managed in the %BRAND_OFFICE_365_SHORT% cloud are said to have cloud identities, or cloud IDs. If you want cloud IDs for your users, but have several hundred (or more) users and mailboxes to migrate to %BRAND_OFFICE_365_SHORT%, you might consider using directory synchronization initially to move users to the %BRAND_OFFICE_365_SHORT% cloud. After all your users have been moved to %BRAND_AZURE_ACTIVE_DIRECTORY% and assigned %BRAND_OFFICE_365_SHORT% mailboxes, you can then switch to managing them exclusively in the %BRAND_OFFICE_365_SHORT% admin center.
