Question

You are an Identity Administrator at Contoso. The HR team gives you a CSV file with 480 new seasonal employees to onboard into Microsoft Entra ID. You use the 'Bulk create' option in the Microsoft Entra admin center and upload the CSV. After the operation completes, the bulk operation results show that 47 users were not created. All 47 failed rows share the same problem: their user principal name values used the domain 'contoso.seasonal', which is not registered in the tenant. What is the most efficient way to successfully create these 47 users while following Entra requirements?

Accepted Answer

Correct the UPN suffix in the CSV to use a verified domain (such as contoso.com or contoso.onmicrosoft.com), then re-upload only the corrected rows using Bulk create.

Answer

Add 'contoso.seasonal' as a custom domain and immediately re-upload the failed rows; domain verification is not required for user creation.

Answer

Manually create each of the 47 users one at a time in the admin center, because bulk operations cannot use verified domains for UPNs.

Answer

Re-run the entire original CSV of 480 users using Bulk create so the tenant retries the failed rows automatically.
