Microsoft Dynamics 365 proactive quality updates, or PQUs, deliver cumulative hotfixes to Finance & Supply Chain Management environments automatically with near-zero downtime. They help Microsoft get important fixes to customers faster, but they also make it important for Dynamics 365 teams to coordinate testing, customizations, and release schedules more carefully.
For organizations running Dynamics 365 Finance and Supply Chain Management, understanding when PQUs occur and how they affect sandbox and production environments can help avoid unnecessary retesting and deployment conflicts.
Key Highlights
- Proactive quality updates are cumulative Dynamics 365 hotfix builds delivered automatically with near-zero downtime.
- Starting with version 10.0.47, Microsoft moved PQUs from a 28-day schedule to a biweekly cadence.
- Microsoft deploys PQUs gradually through a safe deployment process, beginning with sandbox environments before production.
- Customers cannot delay, reschedule, pause, or request exclusion from the standard PQU cadence.
- Dynamics 365 teams should coordinate customization releases and testing around the PQU schedule to avoid version inconsistencies and repeated testing.
What Are Proactive Quality Updates in Dynamics 365?
Proactive quality updates are cumulative builds that Microsoft uses to deliver fixes to supported Dynamics 365 Finance & Supply Chain Management environments without requiring customers to wait for the next full service update.
Before PQUs, many customers did not receive fixes for service problems until they installed their next service update. That meant an organization could continue experiencing a known issue even after Microsoft had developed a fix.
PQUs use a push model instead. Microsoft applies the update to eligible environments in the background and rolls it out gradually across regions. The goal is to deliver fixes faster while minimizing disruption to normal operations.
What Does a Dynamics 365 PQU Include?
Microsoft describes PQUs as focused, cumulative updates rather than broad feature releases. The payload is controlled so changes can be deployed safely.
Microsoft uses several processes to reduce the risk associated with these updates:
- Concise update payloads: PQU changes focus primarily on bug fixes, regulatory changes supported through flighting, and qualifying product improvements.
- Safe deployment rollout: Microsoft begins with smaller groups of environments and expands the rollout only after monitoring for problems.
- Fallback through flighting: Certain changes introduced through a PQU can be enabled or disabled if Microsoft identifies an issue during or after deployment.
This staged approach allows Microsoft to detect problems before an update reaches the entire Dynamics 365 customer base.
How Often Are Dynamics 365 Proactive Quality Updates Released?
Starting with Dynamics 365 version 10.0.47, Microsoft moved PQUs from the previous 28-day release schedule to a two-week cadence. The more frequent schedule is intended to reduce the time customers wait for fixes and provide more regular validation cycles in sandbox environments.
Microsoft publishes the and its corresponding application build version. Customers scheduled to receive an update are notified at least five days in advance.
New Finance & Supply Chain Management environments provisioned after August 17, 2023 are automatically enrolled to receive PQUs according to the applicable schedule.
Do Sandbox and Production Receive the PQU at the Same Time?
No. Microsoft applies proactive quality updates to sandbox environments before production.
Under the current process, production receives the update at least five days after the sandbox environment. This gives organizations an opportunity to validate the updated build before it reaches the live environment.
Microsoft also supports optional weekday maintenance scheduling for eligible production environments, allowing organizations to choose maintenance days that better align with their internal testing and release processes. The PQU itself, however, remains part of Microsoft's managed servicing process.
Can You Delay or Pause a Dynamics 365 PQU?
No. Customers cannot normally delay, reschedule, pause, or request exclusion from the standard proactive quality update cadence.
That makes planning particularly important. Instead of treating a PQU like an optional upgrade project, Dynamics 365 administrators and development teams should account for the update schedule as part of their regular release management process.
Microsoft may stop a broader rollout if a critical issue is identified. However, customers should not build their internal release process around the assumption that a scheduled PQU can simply be postponed.
How Can You Review What Is Included in a PQU?
Dynamics 365 teams can review the changes included in an upcoming proactive quality update through Microsoft Dynamics Lifecycle Services.
The basic process is:
- Open Lifecycle Services (LCS) and navigate to the Environment details page for the sandbox environment.
- Locate the latest quality update build under Available Updates and select View Update.
- Export the build information to a CSV or Excel file.
- Filter the exported information by the applicable build version to review the delta payload.
Microsoft recommends exporting this information before the environment is updated. This gives the team a record of the changes included in the PQU and helps identify areas that may require additional validation.
How Do PQUs Affect Dynamics 365 Testing and Customizations?
More frequent sandbox updates make release coordination more important, especially for organizations with customizations.
Consider a team that is midway through testing a customization when its sandbox automatically receives a new PQU. The environment used to begin testing may no longer be running the same build that was originally validated.
Depending on the change and the organization's testing process, some testing may need to be repeated before the customization moves to another environment.
The practical issue is not that PQUs prevent customization. It is that Dynamics 365 teams need to pay closer attention to which versions are running in each environment and when Microsoft-managed updates are scheduled.
How Should Dynamics 365 Teams Prepare for Proactive Quality Updates?
A disciplined release process can reduce conflicts between Microsoft updates and internal development work.
1. Track the Microsoft PQU Schedule
Make the PQU schedule part of release planning rather than treating it as an unexpected infrastructure event. Knowing when sandbox and production updates are expected gives development and testing teams more context when scheduling deployments.
2. Keep Releases Smaller
Smaller, more frequent customization releases can reduce the amount of work exposed to an environment change during testing.
This was already useful when PQUs were less frequent, but the move to a biweekly cadence makes shorter release cycles even more practical.
3. Keep Environment Versions Aligned
Before testing or promoting a customization, confirm the versions running in the relevant sandbox and production environments.
A mismatch does not automatically prevent deployment, but teams should understand the difference and follow Microsoft's compatibility guidance before moving custom packages between environments.
4. Plan for Regression Testing
A PQU may arrive while other development or testing activity is underway. Teams should determine in advance which business processes, integrations, and customizations require regression testing after an environment changes.
That preparation can make the difference between a routine Microsoft update and an unexpected delay in an internal release.
What Are the Benefits of Proactive Quality Updates in Dynamics 365 F&SCM?
Although the automatic cadence requires more attention to release management, PQUs also address a long-standing problem: environments that go extended periods without receiving available fixes.
Microsoft can now deliver important fixes more quickly instead of waiting for customers to install the next full service update. Regular updates can help keep environments closer to Microsoft's current supported builds and resolve issues users may otherwise continue experiencing.
