Issue Status: RESOLVED

Issue Description: Users’ Microsoft Power Automate flows may not have triggered when users created, updated, or deleted shifts.

More info: Flows that were configured with “When a Shift was created, updated or deleted” may have failed to trigger when users performed the actions in Microsoft Teams.

Final Update: 22/01/2026 09:06:00 AM – Microsoft have identified that our recent efforts to redirect request traffic to alternate portions of infrastructure, responsible for facilitating Microsoft Power Automate flows triggered by Microsoft Teams shifts, caused the impact. We’ve reversed the change by directing the traffic back to its original infrastructure and confirmed through internal testing that the impact is remediated.

Scope of impact: Any user that attempted to create, update, or delete shifts in Microsoft Teams and had a Microsoft Power Automate flow configured with “When a Shift was created, updated or deleted” may have been impacted.

Root cause: Our recent efforts to redirect request traffic to alternate portions of infrastructure responsible for facilitating Microsoft Power Automate flows triggered by Microsoft Teams shifts caused the impact.

Next steps: Microsoft are continuing to review the affected infrastructure to identify the reason it caused impact, so that we can prevent similar impacts from occurring in the future.
