Extend a Dynamics 365 Customer Insights environment for business-account work with the Customer Insights B2B Accounts Add-On. Microsoft 42AA3628F72B is the ordering code for the add-on associated with B2B Accounts. Its purpose is to add account-oriented scope to a Customer Insights deployment where organizations work with business accounts rather than only individual customer records. This keeps the service scope aligned with account-based customer information used across B2B relationship management activities. Use this add-on within a Microsoft cloud environment that already centers on Customer Insights and requires B2B account coverage. It is software, not a physical appliance, cable, or accessory, and it does not replace the underlying Customer Insights service. The B2B Accounts designation separates this requirement from general Customer Insights functionality and from components intended for other Dynamics 365 workloads. Business-to-business environments commonly organize customer relationships around company accounts and associated contacts, making account scope a meaningful selection criterion. The specific distinction is its B2B Accounts focus: select this offer when the required Customer Insights scope concerns business-account data and related B2B customer insight processes. Do not treat the ordering code as a statement of account quantity, user count, service term, or included modules. Those commercial entitlement details depend on the applicable Microsoft offer terms for the tenant. Its role is to extend an existing Customer Insights service with the named B2B Accounts add-on scope.
