Building and customizing solutions using Microsoft 365 Copilot APIs and tools
Hello BATES Jack (EXT) •
What you're seeing is generally expected. In the new Copilot Studio Workflows experience, connections are tied to the identity that created/authenticated them. Giving another user Environment Maker access allows them to open and edit the Workflow, but it does not automatically give them access to use the original maker's authenticated connections.
As a result, when your colleague opens the Workflow, SharePoint, Dataverse, Outlook, and other connector actions may appear disconnected or unusable until they create or authenticate their own connections. Sharing the Workflow is not the same as sharing the underlying connection credentials.
If all connections were created using a dedicated service account, there is currently no general "author credential sharing" model that lets other makers seamlessly edit and test the Workflow using that service account's connections. In practice, each maker usually needs their own connections, unless a connector specifically supports a shared authentication pattern.
So based on your description, this sounds more like a current platform limitation/design behavior around connection ownership rather than a missing Environment Maker permission or overlooked sharing step.
