Use the default solution to customize

This topic applies to Dynamics 365 Customer Engagement (on-premises). For the Power Apps version of this topic, see: Use the Common Data Services Default Solution

When you customize a custom business app, you may work with the default solution. To open the default solution, open solution explorer.


After you have the default solution open, use Ctrl+D to create a favorite or bookmark in your browser. This will help you open it faster even if you don’t already have the web application open.

Every environment has a default solution and it has some unique properties. The default solution contains all the solution components available in your environment. Other solutions may include a subset of the solution components visible in the default solution, but the default solution contains all of them.


Before you start creating new customizations, remember to change the solution publisher customization prefix. More information: Solution publisher prefix.

Privacy notices

By enabling a solution, you consent to share your data with an external system. Data that is imported from external systems into Microsoft Dynamics 365 (online) is subject to Microsoft Privacy and Cookies.

You can import and export solutions to and from Microsoft Dynamics 365 (online). When you do so, the solutions, which may contain personal information, are transferred over a secure connection between your computer and Microsoft servers. In turn, third-party code imported to Dynamics 365 (online) could eventually transmit Customer Data to an external system (i.e. InsideView) or configure/expand entities that get synchronized (i.e. exported) to other external systems that are controlled by a party other than Microsoft.

If a solution to be imported is meant to transmit Customer Data outside of the security boundaries of Dynamics 365 (online), Administrators are invited to verify the types of Customer Data that will be called by the service/software/application prior to uploading third-party code to their Dynamics 365 (online) instance.
Extraction of Customer Data by third party services/software/applications or solutions is controlled by the customer, not Microsoft. The final destiny and privacy policies applicable to the data points extracted by these external solutions are controlled by the Administrator; adequate review of the policies applicable by the third parties operating these services/software/apps is recommended.
