Customer Engagement guides

The Dynamics 365 CRM apps — Sales, Customer Service, Field Service, Project Operations, Customer Insights, HR — and the Dataverse platform they share.

125 guides · Last updated 2026-09-06

Customer Engagement is Microsoft's name for the CRM half of Dynamics 365: Sales, Customer Service, Field Service, Project Operations, Customer Insights (Journeys and Data), and the Contact Center product. All of them run natively on Microsoft Dataverse, which is why an account created in Sales is the same row a service agent, a field technician, and a marketing journey see — no integration required.

That shared platform is also why the largest sub-section here is Dataverse itself: the security model, plug-ins and the execution pipeline, business rules and workflows, alternate keys, virtual and elastic tables, the Web API, and the tooling ecosystem around XrmToolBox. Understanding Dataverse is what separates a configurator from an architect on these apps.

Start with the app overview for the process you run, then the Dataverse security model and data model fundamentals. The comparisons section covers Sales versus Salesforce, Customer Service versus Zendesk and ServiceNow, and Journeys versus HubSpot.

Dataverse's plug-in and Web API errors get their own troubleshooting guides, decoding the hex error codes (privilege denial, duplicate detection, entity not found) that every Dataverse developer eventually hits and that Microsoft's own error messages describe tersely at best. For a build decision rather than a runtime error, the plug-ins-vs-Power-Automate guide and the low-code-plug-ins-in-Dataverse guide cover when server-side code is actually warranted versus when a flow or a business rule does the job with far less maintenance burden. Security is the sub-section worth reading in full before go-live, not after an audit: the security model, field-level and hierarchical security, and owner teams versus access teams together decide who can see and change what, and retrofitting a security model onto live data is materially harder than designing it first.
