Microsoft Power Platform helps businesses build applications, automate workflows and improve everyday operations. As these solutions become essential to business processes, managing their environments is just as important.
Microsoft has announced changes affecting unmanaged developer environments and Dataverse for Teams environments, with different timelines and transition requirements.
Starting November 15, 2026, organizations will no longer be able to create new environments of these types. Existing environments also have upcoming suspension and decommissioning deadlines.
For IT teams, the priority is to identify affected environments and protect the business solutions that depend on them.
What Is Changing in November 2026?
1. Unmanaged Developer Environments
Power Apps developer environments allow users to build and test applications and workflows. However, unmanaged developer environments lack some of the governance controls available through Managed Environments.
Starting November 15, 2026, users will no longer be able to create new unmanaged developer environments. Signing up for the Power Apps Developer Plan will also stop automatically creating an unmanaged developer environment.
Key dates to remember:
- November 15, 2026: Creation of new unmanaged developer environments ends.
- December 15, 2026: Suspension of existing unmanaged developer environments begins.
- January 15, 2027: Deletion of suspended unmanaged developer environments begins.
This change does not affect existing developer environments that are already managed, or production, sandbox, trial and default environments under this specific deprecation.
Organizations should identify unmanaged developer environments and review the applications, workflows and data they contain. Depending on licensing and business needs, they can convert suitable environments to Managed Environments or move required solutions to another supported environment.
2. Dataverse for Teams Environments
Dataverse for Teams allows users to build apps, workflows and agents using data within Microsoft Teams.
Starting November 15, 2026, users will no longer be able to create new Dataverse for Teams environments.
Existing environments follow a separate timeline:
- November 15, 2026: Creation of new Dataverse for Teams environments ends.
- September 15, 2027: Suspension of existing environments that haven’t been upgraded to Dataverse begins.
- October 30, 2027: Non-upgraded environments are scheduled for decommissioning.
Organizations should review their existing apps, flows, agents and data to determine what needs to be retained.
Where necessary, administrators can plan an upgrade to Dataverse or move required solutions to another suitable Dataverse environment. Before proceeding, they should check licensing, available capacity and technical dependencies.
Why Do These Changes Matter for Businesses?
An application may begin as a small internal project but eventually become essential to daily operations.
For example, a Power Apps solution might manage employee requests, automate approvals, or notify teams about important updates. If its environment becomes unavailable, the business processes depending on it could be disrupted.
IT teams should therefore understand which solutions are still in use, who owns them, and what business activities depend on them.
Three areas deserve particular attention:
- Ownership: Identify environment owners and the teams relying on their solutions.
- Dependencies: Review connected apps, flows, data, permissions and integrations.
- Licensing and capacity: Confirm that the intended destination environment supports the required solutions.
How Should IT Teams Prepare?
A structured review can help businesses protect important solutions without migrating everything unnecessarily.
1. Create an Environment Inventory
Use the Power Platform admin center to identify affected environments. Record their owners, business purpose, recent activity and associated apps, flows, agents and data.
2. Prioritize Business-Critical Solutions
Separate unused prototypes from applications supporting active business processes. Involve business owners to decide what should be retained, migrated or retired.
3. Choose the Right Transition Path
For unmanaged developer environments, assess conversion to Managed Environments where appropriate licensing is available, or move required solutions to another supported environment.
For Dataverse for Teams, evaluate the supported upgrade process or migration to an existing Dataverse environment.
Not every environment needs to be moved. Decisions should reflect business value, technical requirements, licensing and future needs.
4. Test Before Going Live
Before upgrading or moving a solution, review its connections, permissions, data, environment variables and integrations. Test the application and associated workflows in the destination environment before employees rely on them.
This helps identify issues early and reduces the risk of business disruption.
Common Mistakes to Avoid
- Assuming every environment is affected: The unmanaged developer environment deprecation does not apply to existing developer environments that are already managed.
- Waiting until the deadline: Start reviewing environments early enough to resolve licensing and migration issues.
- Treating both changes identically: The two environment types have different timelines and transition options.
- Ignoring dependencies: Check integrations, permissions, licensing and capacity before moving solutions.
- Migrating everything unnecessarily: Preserve useful business solutions and retire those that are no longer needed.
Final Thoughts
The upcoming Power Platform changes give organizations an opportunity to review how their applications, workflows and environments are managed.
For unmanaged developer environments, the immediate priority is to protect useful work before suspension begins on December 15, 2026.
For Dataverse for Teams, businesses should prepare for the end of new environment creation on November 15, 2026, while planning ahead for the September 15, 2027 suspension and October 30, 2027 decommissioning deadlines.
A clear inventory, defined ownership, appropriate licensing and thorough testing can help organizations manage these changes with less disruption.

Frequently Asked Questions
What changes on November 15, 2026?
Users will no longer be able to create new unmanaged developer environments or new Dataverse for Teams environments. The Power Apps Developer Plan will also stop automatically creating an unmanaged developer environment.
When will existing unmanaged developer environments be suspended or deleted?
Suspension begins on December 15, 2026 and deletion of suspended environments begins on January 15, 2027.
Will all Power Platform environments be affected?
No. Existing developer environments that are already managed, along with production, sandbox, trial and default environments, are outside this specific unmanaged developer environment deprecation.
What happens to existing Dataverse for Teams environments?
Non-upgraded environments are scheduled for suspension beginning September 15, 2027 and decommissioning on October 30, 2027. Organizations should assess whether to upgrade or move the solutions they still need.
Can apps built with Dataverse still be used in Microsoft Teams?
Yes. Apps, flows, and agents built in a suitable Dataverse environment can still be used in Teams, subject to applicable configuration and licensing requirements.
