Is this any possible way to integrate B2C with Microsoft Forms?

Question

By default office365 services are inaccessible for users which are not in Azure AD.

Is this any possible way to provide an access to specific Microsoft Forms based on users which are configured in B2C (not in Azure AD)?

In this case, after logging into b2c, the user could access the Microsoft Form, for other external users which are not in b2c access to the form would be impossible.

Answer 1

Hi @Mikhail Delly , I would suggest using B2B for this. O365 has some features that can only be used with B2B, and you can access Forms this way. The document I linked shows how to connect to SharePoint and OneDrive but the same applies to Forms. Please let me know if you have any questions about this or B2B in general and I can help you further.

If this answer helped you please mark it as "Verified" so other users may reference it.

Thank you,

@James Hamil

Thanks for your assist.

So as I understand there is NO possibility to share forms with b2c users without using b2b or AzureAD account. There is only possibility is to share form with "Anyone" option but in those case the access will be unrestricted at all.

Am I correct that you meant the document B2B SharePoint OneDrive Integration not the "B2B for this"?
So according to this article we have to use the following cmdlets using SharePoint Online Management Shell
Set-SPOTenant -EnableAzureADB2BIntegration $true
Set-SPOTenant -SyncAadB2BManagementPolicy $true
and in those case guest users will be able to use OneDrive and SharePoint. Correct?

Is this applies to MS form responses too? Cause for the Microsoft Forms in some sources I've found that Internal Form is restricted even for guest users
source 1
source 2
For this moment I still have "You don't have permission to view or respond to this form" even for the guest users.

Is it possible to provide more detailed information how to share the internal form to let guest (B2b) users submit it and send the responses?
