Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Shawn,
Welcome to the Microsoft Q&A forum.
Based on your description, one of the accounts is unable to sign in because it is not receiving the Multi-Factor Authentication (MFA) verification code.
In this situation, you will need to contact your organization's administrator (typically your IT department) and request that they reset MFA for the affected account. The next time you sign in, you will be prompted to set up MFA again, which will usually resolve the issue.
To reset MFA for the account, please refer to the documentation below and follow the provided instructions:
Manage authentication methods for Microsoft Entra Multi-Factor Authentication
Note: Resetting MFA for a company account can only be performed by an administrator within your organization.
I hope this information is helpful
