Tenancies and deployment scopes for SharePoint Add-ins


The SharePoint Add-In model in SharePoint Online has been retired as of November 27th 2023, checkout the full retirement announcement to learn more.

Retirement means that the feature will not get any new investments, but it's still supported. End-of-life means that the feature will be discontinued and is no longer available for use.

A SharePoint tenancy is a set of site collections in either a SharePoint farm or in SharePoint Online. In SharePoint Online, the site collections belong to a single customer account. In a SharePoint farm, the site collections can be all the site collections in a SharePoint web application or a subset of them, or it can be a set of site collections from across multiple web applications in the farm. A tenancy can have a SharePoint add-in catalog just as a SharePoint web application can.

Tenancies and add-in scope

A SharePoint Add-in has an add-in scope. The two possible add-in scopes are web scope or tenant scope. The difference is not an intrinsic property of the add-in, and you, the developer, do not decide what the scope of your add-in is. The decision is made by tenant administrators as a side effect of how the add-in is installed.

After an add-in is uploaded to the add-in catalog of a tenancy, it is immediately available to be installed on websites within the tenancy on a website-by-website basis. Add-ins that are installed this way have web scope.

Tenant administrators have another option, however. They can choose to batch install the add-in to a subset of websites within the tenancy. Add-ins that are installed in this way have tenant scope. The tenant admin can specify which websites the add-in is installed to by means of a list of managed paths, a list of site templates, or a list of site collections. An add-in that has been batch-installed can only be uninstalled by a tenant administrator. When the tenant admin uninstalls the add-in, it is uninstalled from every website in the tenancy. Users can't uninstall a batch-installed add-in on a website-by-website basis. The same principle applies to updating a batch-installed add-in: only a tenant administrator can do it, and it is batch-updated on every website in the tenancy where it is installed.

If an add-in that includes an add-in web is batch-installed, only one add-in web is created, and it is shared by all the host websites on which the add-in is installed. The add-in web is located in the site collection of the organization's add-in catalog.

When new site collections are created in the tenancy, add-ins that were previously batch-installed are automatically installed on the new site collection.


Add-in scope should not be confused with Feature scope. Feature scope determines where the elements in a Feature are deployed. The possibilities include Farm, WebApplication, Site (that is, site collection), and Web. Only Web is permitted for Features in SharePoint Add-ins (both host web features and features inside a .wsp in an add-in package).

Add-in scope should also not be confused with add-in permission levels. SharePoint Add-ins can request permissions to all or selected parts of SharePoint content at the levels of list, web, site collection, and tenancy. Installing an add-in with tenant scope does not give it permissions that it would not otherwise have, nor does it cancel key provisions of the SharePoint security model. For more information about add-in permissions, see Add-in permissions in SharePoint.

Limitations of tenant-scoped add-ins

The following types of add-ins will not work correctly when batch-installed:

  • Add-ins that contain a custom action for the ribbon (custom actions that are deployed as menu items are allowed)
  • Add-ins that contain an add-in part

In addition, note again that installation with tenant scope is not possible in the Office 365 Small Business Premium version of SharePoint Online.

How to install, uninstall, and update an add-in on multiple websites in a tenancy

Regardless of whether an add-in is installed from the Office Store or from an add-in catalog, tenant admins can install it to multiple websites in a tenancy, uninstall it, and update it by using the following procedures.

To install a SharePoint Add-in to multiple websites

  1. Go to the Site Contents page of the corporate catalog website.

  2. Select Add an add-in, and install the add-in just as you would on any other SharePoint website.

  3. After the add-in is installed, hover over the link to the add-in on the Site Contents page. A "..." link appears.

  4. Select the link, and a callout appears.

  5. Select Deployment on the menu.

  6. Use the deployment UI that opens to specify the site collections to which you want the add-in installed. You can filter by managed paths, site templates, or URLs. The filters have a logical "OR" relationship: the add-in is installed to the union of all the site collections that pass any one or more of the filters.

  7. Select OK.

To uninstall a batch-installed SharePoint Add-in

  1. Go to the Site Contents page of the corporate catalog website.

  2. Hover over the link to the add-in on the Site Contents page. A "..." link appears.

  3. Select the link, and a callout appears.

  4. Select Remove on the callout.

To update a batch-installed SharePoint Add-in

  1. Go to the Site Contents page of the corporate catalog website. If there is an update available for an add-in, a message appears next to the add-in. There will be a link to update the add-in.

  2. Select the link to update the add-in.

  3. When you are prompted to approve the permission requests of the add-in, select Trust It.
