Users may be unable to run run-only workflows from Microsoft Teams

Title: Users may be unable to run run-only workflows from Microsoft Teams User impact: Users may have been unable to run run-only workflows from Microsoft Teams. More info: As a result of our initial fix deployment, users were able to run "run-only workflows" through the "workflows" button in Microsoft Teams. However, running "run-only workflows" by hovering and selecting "More actions" > "Create workflows" was still an impacted scenario. Affected users were unable to run workflows in Teams when those workflows were configured to be executed by designated users without requiring those users to own or edit the workflow. Users received the following error message: "Missing Trigger URI" As a way to have avoided the issue, impacted users could've been granted Owner or Co-owner permissions for the affected workflow. Final status: We've completed the deployment of our fix and confirmed after monitoring our service health telemetry that impact is remediated. Scope of impact: Users attempting to run "run-only workflows" from Microsoft Teams may have been impacted. Start time: Tuesday, June 30, 2026, at 7:00 AM UTC End time: Friday, October 2, 2026, at 11:26 PM UTC Root cause: A recent service update introduced a code regression that affected how Microsoft Teams processed shared workflow requests, which prevented some users from running "run-only workflows" from Microsoft Teams. Next steps: - We're reviewing our update procedures to understand why impact to how Microsoft Teams processes shared workflow requests wasn't caught during the testing phase. This will help drive service improvements by proactively identifying similar issues in the future and improve our update testing processes. This is the final update for the event.
