Transition Classic Mode UI to Unified Client Interface

On 10 September 2019, Microsoft announced that per October 2020, the Classic Mode UI (User Interface – in short, the look, feel and navigation of the application) will be phased out and only the new Unified Client Interface (UCI) is available.

Unified Interface is the new client interface that gives the same user experience on any device, whether you are on a browser, tablet or phone. Interactive dashboards are available across all devices to view your information and drill down into it. Unified Interface therefore allows you to design your processes from an app point of view. If you are curious about how this looks, please take a look at the Microsoft video below.


Valentijn Lansbergen, Senior Consultant Customer Engagement at HSO, wrote another blog on this topic (for now in Dutch only).

Using Classic UI after the October 2019 update

With the 2019 October release, Microsoft is encouraging their installed base to transform their Classic UI Forms to the Unified Interface. Customers who have not yet started the transition or don’t use any Custom or Standard Microsoft Hub Apps, typically make use of the Classic UI. Based on customer specific settings or historical upgrade paths related to their D365 CE environment, End Users may notice automatically being logged in to D365CE via the Unified Client Interface rather than the Classic Web Interface they are familiar with.

In order to revert back to the Classic UI go to the ‘Use the New Unified Interface only (recommended’) setting and set it to NO, within the System Settings – General Tab.

In case some users need to make use of the classic UI whereas the organizational requirements demand the above setting to be Yes (as recommended) please feel free to contact the service desk.

From unmanaged to managed solutions

Microsoft advises to only use unmanaged solutions in development environments and deploy them as managed solution to any target environment. However, in practice, this can be challenging due to the need for extensive flexibility on one hand and maintaining consistency when configuring and importing Dynamics 365 solutions.

Because of these factors, and the fact that managed solutions appeared less mature in the past, we have chosen to use unmanaged solutions in some of our customers’ target environments. In addition, HSO also has customers that implement unmanaged customizations in their production environment or perform a copy of their production environment to their development environment to refresh the data and configuration.

Microsoft recently invested a lot in the development of managed solutions, and we have positive experience at customers. Therefore, we strongly recommend users to follow the guideline of Microsoft, as this will help you to maintain consistent CE environments. It also helps you to benefit from the updates Microsoft is increasingly pushing. Of course, our service and delivery teams can assist you with any necessary changes.

All about the October 2019  Fall release

Recently, a major release for Dynamics 365 CE online has become generally available. The October release is part of The Dynamics 365 release plan (formerly release notes) for the 2019 release wave 2. This plan describes all new features releasing from October 2019 through March 2020.

You can browse the release plan online and download the document as a PDF file. The PDF file also includes information about Power Apps, Microsoft Flow, the Common Data Model and data integration.

Deprecated features

With each new release, Microsoft announces features to be deprecated in future releases. Two announcements are the deprecation of Task Flows and Process Dialogs, which will be deprecated and removed by 1 October 2020. You can find more information, suggested replacements and an overview of all deprecation announcements here.

Automated deployment D365 CE

When deployments of CE increase in size and complexity, the need for a quicker and more stable release process grows. Microsoft already deploys updates on a weekly basis, the interval of these updates is expected to keep getting shorter in the future.

We recommend addressing this topic with your IT-team and your HSO support or delivery manager. Automated CE deployments can have a lot of benefits and we are happy to discuss these with you.
