Fix Guest User Not Receiving SharePoint Verification Code
Question details
Guest users with personal Gmail accounts are being prompted for organizational information instead of receiving a standard SharePoint email verification code.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- An administrator or site owner is trying to share files or sites with an external guest using a personal Gmail address.
- Observed behavior
- The guest user does not receive the verification code to their Gmail account. Instead, the verification flow unexpectedly requests a professional organizational address, preventing the guest from accessing the shared content.
Ensure you have Microsoft 365 administrator privileges, as you will need access to the Microsoft 365 admin center and Microsoft Entra ID to investigate backend guest-access configurations.
Verify Guest Account in Microsoft Entra ID
Confirm that the guest's Gmail account has been properly added and is recognized as a guest in your organization's directory.
Before escalating the issue, it is crucial to ensure that the Microsoft Entra B2B collaboration settings successfully registered the external user.
Log in to the Microsoft Entra admin center using your administrator credentials.
Go to 'Identity' > 'Users' > 'All users' in the left-hand navigation menu.
Enter the guest's Gmail address in the search bar. Verify that the account appears and the 'User type' is explicitly listed as 'Guest'.
Go back to SharePoint and share a test file or site directly with this Gmail account to see if it still prompts for organizational information instead of sending the verification code.
Collect Network Traces and Open a Support Request
Because this specific verification flow issue requires backend investigation by Microsoft, gather network logs and submit a support ticket.

Frequently Asked Questions
Why is SharePoint asking a personal Gmail guest for an organizational account?
This usually happens due to a browser caching issue, an active conflicting login session, or a backend configuration glitch in Microsoft Entra ID's external identities B2B collaboration settings.
How should external users normally authenticate in SharePoint?
When an external guest without a Microsoft account (like a Gmail user) is invited, they should normally receive a one-time passcode (OTP) sent to their email address to verify their identity.
Can I fix this issue without contacting Microsoft Support?
You can try having the guest open the sharing link in an Incognito/Private browsing window to rule out cache issues. If the prompt for an organizational account persists, it is a backend issue that requires Microsoft Support to resolve.
