Hi @Benoit Bourque Thank you for contacting the Q&A Forum. Regarding your issue, this is likely related to licensing or permissions. These are some common reasons behind the error:
- Missing Required License
Lifecycle Workflows is part of Microsoft Entra ID Governance, which requires one of the following licenses:
- Microsoft Entra ID Governance
- Microsoft Entra Suite P2
The license is assigned to the operations administrators. Without one of these, even a Global Administrator will receive a 401 error when trying to access Lifecycle Workflows.
- Expired or Incorrect Permissions
If you're using an app registration or service principal to access workflows (e.g., via API), the error can also occur if:
- The client secret has expired.
- The app lacks required Graph API permissions (like User.Read.All, Group.Read.All).
- Admin consent has not been granted
- Role Limitations
Even though you're a Global Administrator, if you're accessing via a delegated app or a role with limited scope (like Windows 365 Administrator), you may still get the error message.
I would suggest these following fixes for you to apply:
- Verify Licensing
- Go to Microsoft Entra Admin Center → Billing → Licenses.
- Ensure your tenant has Microsoft Entra ID Governance or Entra Suite P2 licenses.
- Assign the license to your user account.
- Check Access Method
If you're using a service principal or app, ensure:
- The client secret is valid.
- The app has the correct Graph API permissions.
- Admin consent has been granted.
- Try a Different Admin Account: If possible, test access with another licensed Global Admin to rule out account-specific issues.
Kindly let me know if this work for you and please let me know if you have any further question.
