Power Platform Community Forum Thread Details

This flow has been operating for more than a year and yesterday suddenly stop working. The error message I get is :

I first thought it has something to do with the connections and even when they were all good, It keeps failing in the "Get use profile (v2)"

step.

"Attempted to perform an unauthorized operation."

Can you try the below steps:

Re‑authenticate the Office 365 Users connection
- Remove + re‑create the connection using a known, licensed account.
Test Get user profile (V2) in isolation
- Create a quick test flow with only this action to confirm it’s not downstream.
Verify the account used by the connection
- Confirm:
  - User still exists and is enabled
  - License includes Azure AD / Entra ID access
  - No recent role or security changes
Check Conditional Access & sign‑in logs
- Look for blocked or failed sign‑ins tied to Power Automate or Graph.
If recently changed, roll back or switch identity
- Temporarily use a different service or admin account to validate root cause.
