Hello Christophe,
When a Windows 11 Professional device is joined to Azure AD, it operates under cloud-based identity management, which prevents direct domain joins or switching to local accounts without first disconnecting from Azure AD. To resolve this, you'll need to:
Disconnect the device from Azure AD:
- Go to Settings > Accounts > Access work or school.
- Select the connected Azure AD account and click Disconnect.
- You may need admin credentials associated with the Azure AD tenant to complete this step.
Create a local account:
- Navigate to Settings > Accounts > Other users.
- Click Add account, then choose I don’t have this person’s sign-in information > Add a user without a Microsoft account.
- Set up the local account and assign admin rights if needed.
Join the company domain:
- After signing in with the local account, go to Settings > System > About > Domain or workgroup and select Join a domain.
- Enter your domain credentials and restart the PC to complete the process.
