B2B Guest Account Type Identification

Hello!

Is there a way to identify whether an invited/verified B2B Guest account in our tenant is a Microsoft Account or a Work/School Account?

Explanation: We run into a lot of issues sharing PowerBi reporting with our invited B2B guests. One particular issue that plagues us is Guest users that managed to create a Microsoft Account (personal) with their work email address, before the change that prevents them from doing so. The Microsoft Accounts don't play nice, and what we end up having to do is end-user support where we walk them through creating a Work or School Account in their own tenant's domain, and making sure they understand they need to login as that account. It would greatly help to be able to identify which accounts need to be fixed, and if I could somehow tell within our tenant which accounts are personal Microsoft Accounts instead of Work/School Accounts, I'd be able to find all of the problem children at once.

Thank you,
Chris

Hi @mollerupc-9842,

Thanks for using Microsoft Q&A !!

You could use Source property of a B2B user to identify if the user is from a "Microsoft Account" or "External Azure AD" after invitation redemption. You can find this property available on Azure Portal but unfortunately this property is not available through Azure PowerShell/Azure CLI or Microsoft Graph. Please upvote the existing uservoice so that products team can plan to include it in future releases.

Also, there is an alternative method described over here which you could try to use. I haven't tried this but I see few users are able to get the required information through this approach. Please let me know if you have any questions.

Thanks
Saurabh

Saurabh,

That's exactly what I was looking for, and it verified the behavior for me as well! Thank you so much! That also explains why the properties returned using Powershell didn't give me anything that I could use to identify it.

One other note: The "Source" property is not present in the Azure portal AAD Preview mode. It took me a minute to figure out that I needed to disable the Preview features in order to see the Source column.

Thanks again!
Chris
