Requirements for running Office Add-ins

This article describes the software and device requirements for running Office Add-ins.

Note: When you build your add-in, if you plan to publish your add-in to the Office Store, make sure that you conform to the Office Store validation 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 4.12 and the Office Add-in host and availability page).

For a high-level view of where Office Add-ins are currently supported, see the Office Add-in host and platform availability page.

Server requirements

To be able to install and run any Office Add-in, you first need to deploy the manifest and webpage files for the UI and code of your add-in to the appropriate server locations.

For all types of add-ins (content, Outlook, and task pane add-ins and add-in commands), you need to deploy your add-in's webpage files to a web server, or web hosting service, such as Microsoft Azure.

Note: When you develop and debug an add-in in Visual Studio, Visual Studio deploys and runs your add-in's webpage files locally with IIS Express, and doesn't require an additional web server.

For content and task pane add-ins, in the supported Office host applications - Access web apps, Word, Excel, PowerPoint, or Project - you also need an add-in catalog on SharePoint to upload the add-in's XML manifest file.

To test and run an Outlook add-in, the user's Outlook email account must reside on Exchange 2013 or later, which is available through Office 365, Exchange Online, or through an on-premises installation. The user or administrator installs manifest files for Outlook add-ins on that server.

Note: POP and IMAP email accounts in Outlook don't support Office Add-ins.

Client requirements: Windows desktop and tablet

The following software is required for developing an Office Add-in for the supported Office desktop clients or web clients that run on Windows-based desktop, laptop, or tablet devices:

Client requirements: OS X desktop

Outlook for Mac, which is distributed as part of Office 365, supports Outlook add-ins. Running Outlook add-ins on Outlook for Mac has the same requirements as Outlook for Mac itself: the operating system must be at least OS X v10.10 "Yosemite". Because Outlook for Mac uses WebKit as a layout engine to render the add-in pages, there is no additional browser dependency.

The following are the minimum client versions of Office for Mac that support Office Add-ins:

  • Word for Mac version 15.18 (160109)
  • Excel for Mac version 15.19 (160206)
  • PowerPoint for Mac version 15.24 (160614)

Client requirements: Browser support for Office Online web clients and SharePoint

Any browser that supports ECMAScript 5.1, HTML5, and CSS3, such as Internet Explorer 11 or later, or the latest version of Microsoft Edge, Chrome, Firefox, or Safari (Mac OS).

Client requirements: non-Windows smartphone and tablet
