Deploy and publish Office Add-ins

You can use one of several methods to deploy your Office Add-in for testing or distribution to users. The deployment method can also affect which platforms surface your add-in.

Note

For information about how end users acquire, insert, and run add-ins, see Start using your Office Add-in.

Primary publication methods

The following table summarizes the primary publication methods that can be used regardless of which type of manifest the add-in uses. If the add-in uses the add-in only manifest, see also Additional publication methods for the add-in only manifest.

Method Use
Sideloading As part of your development process, to test your add-in running on Windows, iPad, Mac, or in a browser. (Not for production add-ins.)
AppSource To distribute your add-in publicly to users.
Microsoft 365 admin center In a cloud deployment, to distribute your add-in to users in your organization by using the Microsoft 365 admin center. This is done through Integrated Apps or Centralized Deployment.

Production deployment methods

The following sections provide additional information about the deployment methods that are most commonly used to distribute production Office Add-ins to users.

AppSource

You can make your add-in available through AppSource, Microsoft's online app store which is accessible through a browser and through the UI of Office applications. Distribution through AppSource gives you the option of including installation of your add-in with the installation of your Windows app or a COM or VSTO add-in. For more information, see Publish to your Office Add-in to AppSource.

Note

If you plan to publish your add-in to AppSource and make it available within the Office experience, make sure that you conform to the Commercial marketplace certification policies. For example, to pass validation, your add-in must work across all platforms that support the methods that you define (for more information, see section 1120.3 and the Office Add-in application and availability page).

Integrated Apps via the Microsoft 365 admin center

The Microsoft 365 admin center makes it easy for an administrator to deploy Office Add-ins to users and groups in their organization. Add-ins deployed via the admin center are available to users in their Office applications right away, with no client configuration required. You can use Integrated Apps to deploy internal add-ins as well as add-ins provided by independent software vendors (ISVs). Integrated Apps also shows admins add-ins and other apps bundled together by same ISV, giving them exposure to the entire experience across the Microsoft 365 platform.

When you link your Office Add-ins, Teams apps, SharePoint Framework (SPFx) apps, and other apps together, you create a single software as a service (SaaS) offering for your customers. For general information about this process, see How to plan a SaaS offer for the commercial marketplace. For specifics on how to create Integrated Apps, see Configure Microsoft 365 App integration.

For more information on the Integrated Apps deployment process, see Test and deploy Microsoft 365 Apps by partners in the Integrated apps portal.

Note

If your add-in uses the unified manifest for Microsoft 365 and is distributed with the Microsoft 365 admin center, it won't be installable by users with certain versions of Office. For more information, see Office Add-ins with the unified app manifest for Microsoft 365 - Client and platform support.

Important

Customers in sovereign or government clouds don't have access to Integrated Apps. They use Centralized Deployment instead. Centralized Deployment is a similar deployment method, but doesn't expose connected add-ins and apps to the admin. For more information, see Determine if Centralized Deployment of add-ins works for your organization.

Deploy updates

When you add features or fix bugs in your add-in, you'll need to deploy the updates. If your add-in is deployed by one or more admins to their organizations, some manifest changes will require the admin to consent to the updates. Users remain on the existing version of the add-in until the admin consents to the updates. The following manifest changes will require the admin to consent again.

Note

Whenever you make a change to the manifest, you must raise the version number of the manifest.

Additional publication methods for the add-in only manifest

The following table summarizes publication methods that are available only when the add-in uses the add-in only manifest.

Method Use Support limitations
Network share As part of your development process, to test your add-in running on Windows computers other than your development computer after you have published the add-in to a server other than localhost.
  • Not supported for production add-ins.
  • Not supported for Outlook add-ins.
  • Not supported for testing on iPad, Mac, or the web.
SharePoint catalog In an on-premises environment, to distribute your add-in to users in your organization.
  • Not supported for Outlook add-ins.
  • Not supported for Office on Mac.
  • Not supported for add-ins with any feature that requires a <VersionOverrides> element in the add-in only manifest.
Exchange server In an on-premises or online environment, to distribute Outlook add-ins to users. Only supported for Outlook add-ins.

SharePoint app catalog deployment

A SharePoint app catalog is a special SharePoint site collection that you can create to host the manifests (add-in only manifest type) of a Word, Excel, or PowerPoint add-in. If you're deploying add-ins in an on-premises environment and none of the add-in users use a Mac, consider using a SharePoint catalog. For details, see Publish task pane and content add-ins to a SharePoint catalog.

Because SharePoint catalogs don't support new add-in features implemented in the VersionOverrides node of the manifest, including add-in commands, for these add-ins, we recommend that you use Centralized Deployment via the admin center if possible.

Outlook add-in Exchange server deployment

For on-premises and online environments that don't use the Microsoft Entra identity service, you can deploy Outlook add-ins via the Exchange server.

Outlook add-in deployment requires:

  • Microsoft 365, Exchange Online, or Exchange Server 2016 or later
  • Outlook 2016 or later

To assign and manage add-ins for your tenants and users, use Exchange PowerShell. For more information, see Add-ins for Outlook in Exchange Server and Add-ins for Outlook in Exchange Online.

It's important to note that some versions of Outlook clients and Exchange servers may only support certain Mailbox requirement sets. For details about supported requirement sets, see Requirement sets supported by Exchange servers and Outlook clients.

GoDaddy Microsoft 365 SKUs

Microsoft 365 subscriptions provided by GoDaddy have limited support for add-ins. The following options are not supported.

  • Deployment through the Microsoft Admin Center.
  • Deployment through Exchange servers.
  • Acquiring add-ins from AppSource.
