I have external guests using a PowerApp - it works... is that ok?!

[davidstone]

So I've created a PowerApps custom list form, we have guest users in our AD and they have been added as users on the sharepoint site hosting the list.

I have people successfully using the form, complete with the PowerApps customisations, 100% working.

I just want some validation that this is supposed to happen? Is it just because it's a list form, rather than a full PowerApp? More importantly, will it continue to work??

Hi @davidstone ,

According to https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/customize-list-form:

Q: What happens when guest users access a list that has a custom form?

A: Guest users get an error message if they try to access a list form that's been customized using PowerApps.

Please check on the Office365 Admin Center of these users and check if they have the PowerApps license there.

Regards,

Mona

I don't have access to the admin center unfortunately, but I do know there is no policy or plan to allocate PowerApps licenses to the guests in this tenant.

Is it perhaps because those users have a PowerApps license in their own tenant, and they are authenticating using the same email?
