Hello @Dan D,
Thank you for connecting with me offline.
As we observed, the affected users in your tenant still have the on-premises sync status enabled, which is the primary reason you're unable to reset their passwords from the Azure portal. Since your on-premises Active Directory was decommissioned some time ago, we needed to convert these synced users into cloud-only users.
To achieve this, we followed the steps below using Microsoft Graph Explorer to disable directory synchronization:
- Open Microsoft Graph Explorer.
- Sign in using a Global Administrator account.
- Use the following PATCH request (replace
{organization-id}
with your actual Tenant ID):
PATCH https://graph.microsoft.com/beta/organization/{organization-id} (Replace org id with Tenant ID)
- Navigate to the Modify Permissions tab and grant Organization.ReadWrite.All permission (consent on behalf of the organization).
- In the Request Body, enter the following JSON:
{
"onPremisesSyncEnabled": false
}
- Click Run Query.
Note: It may take 4–5 minutes for the changes to reflect in the Azure portal.
After completing these steps, the synced users were successfully converted to cloud-only users, and you are now able to reset their passwords via the Azure portal.
