Publish task pane and content add-ins to a SharePoint catalog

An add-in catalog is a dedicated site collection in a SharePoint web application or SharePoint Online tenancy that hosts document libraries for Office and SharePoint Add-ins. To make Office Add-ins accessible to users within their organization, administrators can upload Office Add-ins manifest files to the add-in catalog for their organization. When an administrator registers an add-in catalog as a trusted catalog, users can insert the add-in from the insertion UI in an Office client application.


  • Add-in catalogs on SharePoint do not support add-in features that are implemented in the VersionOverrides node of the add-in manifest, such as add-in commands.
  • If you’re targeting a cloud or hybrid environment, we recommend that you use Centralized Deployment via the Office 365 admin center to publish your add-ins.
  • SharePoint catalogs are not supported for Office for Mac. To deploy Office Add-ins to Mac clients, you must submit them to AppSource.

Set up an add-in catalog

Complete the steps in one of the following sections to set up an add-in catalog on SharePoint or on Office 365.

To set up an add-in catalog for on-premises SharePoint


The UI in on-premises SharePoint still refers to add-ins as apps.

  1. Browse to the Central Administration Site.

  2. In the left task pane, choose Apps.

  3. On the Apps page, under App Management, choose Manage App Catalog.

  4. On the Manage App Catalog page, make sure you have the right web application selected in the Web Application Selector.

  5. Choose View site settings.

  6. On the Site Settings page, choose Site collection administrators to specify the site collection administrators, and then choose OK.

  7. To grant site permissions to users, choose Site Permissions, and then choose Grant Permissions.

  8. In the Share 'App Catalog Site' dialog box, specify one or more site users, set the appropriate permissions for them, optionally set other options, and then choose Share.

  9. To add an add-in to the Office Add-ins add-in catalog, choose Apps for Office.

To set up an add-in catalog on Office 365

  1. On the Office 365 admin center page, choose Admin, and then choose SharePoint.

  2. In the left task pane, choose add-ins.

  3. On the add-ins page, choose Add-in Catalog.

  4. On the Add-in Catalog Site page, choose OK to accept the default option and create a new add-in catalog site.

  5. On the Create Add-in Catalog Site Collection page, specify the title of your Add-in Catalog site.

  6. Specify the web site address.

  7. Set the Storage Quota to the lowest possible value (currently 110). You will only be installing add-in packages on this site collection and they are very small.

  8. Set the Server Resource Quota to 0 (zero). (The server resource quota is related to throttling poorly performing sandboxed solutions, but you won't be installing any sandboxed solutions on your add-in catalog site.)

  9. Choose OK.

  10. To add an add-in to the Add-in Catalog Site, browse to the site you have just created. In the left navigation pane, choose Office Add-ins, and then, to upload an Office Add-in manifest file, choose new add-in.

Publish an add-in to an add-in catalog

To publish an add-in to an add-in catalog, complete the following steps.

  1. Browse to the add-in catalog:

    • Open the SharePoint Central Administration main page.

    • Select Add-ins.

    • Select Manage Add-in Catalog.

    • Choose the link provided, and then choose Office Add-ins on the left navigation bar.

  2. Choose the Click to add new item link.

  3. Choose Browse, and then specify the manifest to upload.

    Content and task pane add-ins in this catalog are now available from the Office Add-ins dialog box. To access them, choose My Add-ins on the Insert tab, and then choose MY ORGANIZATION.

End user experience with the add-in catalog

End users can access the add-in catalog in an Office application by completing the following steps:

  1. In the Office application, go to File > Options > Trust Center > Trust Center Settings > Trusted Add-in Catalogs.

  2. Specify the URL of the parent SharePoint site collection of the add-in catalog.

    For example, if the URL of the Office Add-ins catalog is:

    • https:// _domain_ /sites/ _AddinCatalogSiteCollection_ /AgaveCatalog

    Specify just the URL of the parent site collection:

    • https:// _domain_ /sites/ _AddinCatalogSiteCollection_
  3. Close and reopen the Office application. The add-in catalog will be available in the Office Add-ins dialog box.

Alternatively, an administrator can specify an Office Add-in catalog on SharePoint by using group policy. For details, see the section Using Group Policy to manage how users can install and use Office Add-ins.
