Share a canvas app with guest users
Canvas apps can be shared with guest users of an Azure Active Directory (Azure AD) tenant. This enables inviting external business partners, contractors, and third parties to run your company's canvas apps.
Watch this video to learn how to share an app with guests:
In Azure AD, enable B2B external collaboration for the tenant. More information: Enable B2B external collaboration and manage who can invite guests
B2B external collaboration is enabled by default; however, you need to verify that the settings weren't changed by a tenant admin. For more information about Azure AD B2B, go to What is guest user access in Azure AD B2B?.
Access to an account that can add guest users to an Azure AD tenant. Admins and users with the Guest Inviter role can add guests to a tenant.
To access an app that doesn't connect to Dataverse, the guest user must have a license with Power Apps use rights that matches the capability of the app assigned through one of the following tenants:
- The tenant hosting the app being shared
- The home tenant of the guest user
To access an app that connects to Dataverse, the guest user must have a license with Power Apps use rights that matches the capability of the app. And it must be assigned in the tenant hosting the app. The exception to this prerequisite is when an app is hosted in a Microsoft Dataverse for Teams environment.
Steps to grant guest access
In Azure AD, select New guest user. More information: Quickstart: Add a new guest user in Azure AD
If the guest user doesn't already have a license in their home tenant, assign a license to the guest user.
To assign guest users from admin.microsoft.com, go to Assign licenses to one user.
To assign guest users from portal.azure.com, go to Assign or remove licenses.
You might need to disable the Microsoft 365 admin center preview to assign a license to a guest.
Share the canvas app by doing the following:
After you share an app for guest access, guests can discover and access apps shared with them from the email sent to them as part of sharing. You can also share the app URL directly with the guest instead. To find the URL, go to Power Apps, select Apps on left pane, select the app, and then select the Details tab. The app URL is displayed under Web link.
Considerations and limitations for guest access
- Guests can be assigned the User role or Co-owner role for apps shared with them. However, guests can't edit apps currently. More information: Power Apps support for B2B guest maker (preview).
- Power Apps guest access uses Azure B2B.
- Power Apps Mobile doesn't support authentication using Azure AD direct federation. More information: Sign in using Power Apps Mobile
- Power Apps per app plans are scoped to apps in a specific environment, so they can't be recognized across tenants.
- Power Apps included with Office and Power Apps per user plans have the following characteristics:
- In the Azure public cloud, they're recognized across tenants in guest scenarios because they aren't bound to a specific environment.
- In Azure national or sovereign clouds, they're recognized across tenants in guest scenarios. More information: National clouds, Azure geographies
- Licenses are not recognized across tenants in difference Azure clouds.
Frequently asked questions
What's the difference between canvas app guest access and Power Apps portals?
With canvas apps, you can build an app that's tailored to digitizing business processes, without writing code in a traditional programming language such as C#. Guest access for canvas apps enables teams of individuals made up of different organizations participating in a common business process to access the same app resources that might be integrated with a wide variety of Microsoft and third-party sources. More information: Overview of canvas-app connectors for Power Apps
Power Apps portals provide you the ability to build low-code, responsive websites that allow external users to interact with the data stored in Dataverse. With Power Apps portals, organizations can create websites that can be shared with users external to their organization either anonymously or through the sign-in provider of their choice, such as LinkedIn, Microsoft account, or other commercial sign-in provider.
The following table outlines a few core capability differences between Power Apps portals and canvas apps.
|Guest access in||Interface||Authentication||Accessible data sources|
|Power Apps portals||Browser-only experience||Allows anonymous and authenticated access||Dataverse|
|Canvas apps||Browser and mobile apps||Requires authentication via Azure AD||Any of approximately 150 out-of-the-box connectors and any custom connector|
Can guests access customized forms in SharePoint?
Why is a guest who accesses a customized form in SharePoint prompted for a trial?
If the custom form uses a premium connector, a guest must have a Power Apps license to access the custom form. If the custom form only uses standard connectors, your tenant must allow Microsoft Power Platform internal consent plans to be assigned to users. For more details about Power Platform internal consent plans, read block trial license commands.
Can guests access apps embedded in SharePoint?
Yes. However, access to canvas standalone apps requires that the user have a license with Power Apps user rights that matches the capability of the app; this includes embedded apps. When embedding a canvas app in SharePoint by using the Power Apps embed control, enter the app ID. To do this, enter the app ID in the App web link or ID box.
When embedding a canvas app in SharePoint via the iFrame HTML tag, reference the app by using the full web URL. To find the URL, sign in to Power Apps, select an app, and then select the Details tab. The URL is displayed under Web link.
How is it that guests can open the app shared with them, but no data connections are created?
As is the case with non-guests, the underlying data sources accessed by the app must also be made accessible to the guest.
What license must be assigned to my guest so they can run an app shared with them?
The following table explains whether the guests can run (use) customized Microsoft Lists or SharePoint library forms, canvas apps, and model-driven apps using the referenced license.
|Plan||Customized Microsoft Lists or SharePoint library form (using non-premium connectors)||Customized Microsoft Lists or SharePoint library (using premium connectors)||Canvas app (using non-premium connectors)||Canvas app (using premium connectors)||Model-driven app|
|SharePoint user (without Power Apps license)||✓||✗||✗||✗||✗|
|Power Apps included with Office||✓||✗||✓||✗||✗|
|Power Apps per app plan||✓||✓||✓||✓||✓|
|Power Apps per user plan||✓||✓||✓||✓||✓|

In Power Apps Mobile, how does a guest see apps for their home tenant?
Any user who has used their mobile device to access a canvas app that was published in an Azure AD tenant that isn't their home tenant, must sign out of Power Apps and sign back in to Power Apps Mobile.
In Power Apps Mobile, how does a guest see apps in the guest tenant?
The guest user opens the email they received when an app in the guest tenant was shared, and selects Open the app. This applies to both Azure AD and Microsoft account users.
Must a guest accept the Azure AD guest invitation before an app can be shared with them?
No. If a guest opens an app that was shared with them before they accepted a guest invitation, the guest will be prompted to accept the invitation as part of the sign-in experience while opening the app.
In which Azure AD tenant are connections created for a guest user?
Connections for an app are always made in the context of the Azure AD tenant the app is associated with. For example, if an app is created in the Contoso tenant, the connections made for Contoso internal and guest users are made in the context of the Contoso tenant.
Can guests use Microsoft Graph via the Microsoft Security Graph connector or a custom connector by using Microsoft Graph APIs?
No, Azure AD guests can't query Microsoft Graph to retrieve information for a tenant in which they're a guest.
Which Intune policies apply to guests who are using my apps?
Intune only applies the policies of a user's home tenant. For instance, if Lesa@Contoso.com shares an app with Wanda@Fabrikam.com, Intune continues to apply Fabrikam.com policies on Wanda's device, regardless of the apps Wanda runs.
Which connectors support guest access?
