Power Platform – Update for read access to custom connector definitions for Basic User role

In October 2026, we are updating read access for custom connector definitions in Power Platform. Users assigned the Dataverse Basic User security role will no longer be able to read solution custom connector definitions unless the connector is owned by that user or explicitly shared with them.

What action do I need to take?
Please take the actions listed below:

• Review environments where users with the Basic User role need to read custom connector definitions.
• Create and assign a custom security role with organization-level Read permission on the Connector table when users need access to all custom connectors in an environment.
• Update internal maker and admin guidance to reflect the new access model.

Why is this action needed?
This update improves security by limiting access to connector definitions and configuration details that were not intentionally shared.

If you need additional assistance, please contact Microsoft Support.
