I'm trying to log into our Business O365 but it is telling me the email address is for a personal account.

If you're encountering an error stating that your email address is linked to a personal account while trying to log into your Office 365 business subscription, it may be due to the fact that Microsoft has implemented restrictions on using work or school email addresses to create personal Microsoft Accounts if the email domain is configured in Microsoft Entra ID. This can lead to confusion when trying to access your business account.

To address this issue, consider the following steps:

1. Check Your Email Address: Ensure that you are entering the correct email address associated with your Office 365 business subscription.
2. Use the Correct Account Type: Make sure you are signing in with a Work or School account that is linked to your organization's Microsoft Entra Directory. If you are using a personal account instead, you will not be able to access your business services.
3. Contact IT or Microsoft Support: If you continue to experience difficulties, reach out to your organization's IT department or Microsoft support for further assistance. They can help verify your account status and ensure you have the necessary access to your Office 365 applications.

If your organization does not have accounts associated with Microsoft Entra Directory or Office 365, you may need to use a personal account to sign in, which would require adjustments to your Services Hub workspace configuration.

Dear @Lloyd Anglican,

Thank you for reaching out to Microsoft Q&A forum.

I understand you’re experiencing issues logging into your Microsoft 365 Business account. This is a common challenge when first setting up or accessing Microsoft 365 services.
As a forum moderator, I genuinely wish I could directly access your account or delve into the backend systems to diagnose and fix this for you. However, our role here is limited to providing general guidance and solutions that can be applied by users.  
The error message “The email is for a personal account” occurs because Microsoft detects that your email address is already registered as a Microsoft Account (MSA) for consumer services, which conflicts with your Work or School Account for business services.

• Work/School Account (Organizational Account): Linked to your business subscription (Microsoft 365 Business/Enterprise).
• Personal Account (MSA): Linked to consumer services like Outlook.com, Xbox, Skype, or personal OneDrive.
• When you purchased Microsoft 365 Business, Microsoft created a domain for your organization (e.g., yourcompany.onmicrosoft.com). Even if your primary email is conflicting, you should be able to log in using the administrative username provided during setup (e.g., ******@yourcompany.onmicrosoft.com). Please check your confirmation email for these credentials.
• For business accounts, the username typically looks like: ******@yourcompany.onmicrosoft.com

For reference: What's the difference between a Microsoft account and a work or school account?
