Receiving "Error Code 0" when uploading CSV to bulk enable per-user MFA

Question

I'm able to enable/disable/enforce Per-User MFA through the Office 365 Admin portal or the Entra ID Admin portal, but only for one user at a time. If I try to use the Bulk Upload option, it fails with "Correlation ID e1fc7f1d-a480-44c3-b694-147f7ed78c91" and "ERROR CODE: 0". This is working from the sample CSV that was downloaded from the Portal. Have tried it with 40 Users, have tried it with 2, always get the same results. Same results if I try it from the 365 Admin Center or the Entra ID Admin Center. Don't really want to enable Security Defaults because I don't like the "Authenticator Only" approach, but don't have enough Azure AD P1 or P2 licenses to cover our Userbase so wasn't sure about setting up CA policies.

Hi @Randy Lawrence

Thank you for posting this in Microsoft Q&A.

I understand you are trying to bulk enable per-user MFA through the Office 365 Admin portal or the Entra ID Admin portal, but it fails with "Correlation ID e1fc7f1d-a480-44c3-b694-147f7ed78c91" and "ERROR CODE: 0".

The "Error Code 0" message is a generic error message that indicates that the operation failed, but the reason for the failure is not known. Here are some troubleshooting steps that you can try:

1.Check the format of the CSV file: Verify that the CSV file is in the correct format and matches the template given by Microsoft. The CSV file has columns for Username and MFA status.

2.Try logging in to the Microsoft Entra admin center using a different browser and attempting to utilize the bulk update option.

Hope this helps. Do let us know if you any further queries.

Thanks,
