Office Online Server now available

We are excited to announce the release of Office Online Server (OOS), which allows organizations to deliver browser-based versions of Word, PowerPoint, Excel and OneNote, among other capabilities. Microsoft recognizes that many organizations still value running server products on-premises for a variety of reasons. With OOS, you get the same functionality we offer with Office Online in your own datacenter. OOS is the successor to Office Web Apps Server 2013.

OOS scales well for your enterprise whether you have 100 employees or 100,000. The architecture enables one OOS farm to serve multiple SharePoint, Exchange and Skype for Business instances. OOS is designed to work with SharePoint Server 2016, Exchange Server 2016 and Skype for Business Server 2015. It is also backwards compatible with SharePoint Server 2013, Lync Server 2013 and, in some scenarios, with Exchange Server 2013. You can also integrate other products with OOS through our public APIs.

While OOS runs on your own servers, we are working hard to give you the same experiences you would get if you used our cloud service. For example, real-time co-authoring will now be enabled in Office Online Server. We will deliver most of the new Office Online features to OOS through regular updates.

When used with other servers, OOS makes a variety of scenarios possible:

  • When you integrate OOS with SharePoint Server 2016, generally available starting today, you can create, share and collaborate on Word, PowerPoint, Excel and OneNote files in your browser. Most notably, OOS with SharePoint lets multiple people work in a document at the same time and see everyone’s changes as they happen. OOS also works with SharePoint Server 2013, Lync Server 2013 with Office Web Apps Server 2013 and, in some scenarios, with Exchange Server 2013. So be at ease if you’re still running them—you will not need to run both Office Web Apps Server 2013 and OOS.
  • By integrating OOS with Exchange Server 2016, you can view and edit Office file attachments in Outlook on the web and send back a reply without ever leaving your browser.
  • With Skype for Business Server 2015, OOS enables high fidelity viewing of PowerPoint Online when sharing PowerPoint presentations during meetings.

With exception of those who have access through the Open Program, customers with a Volume Licensing account can download OOS from the Volume License Servicing Center at no cost and will have view-only functionality, which includes PowerPoint sharing in Skype for Business. Customers that require document creation, edit and save functionality in OOS will need to have an on-premises Office suite license with Software Assurance or an Office 365 ProPlus subscription. Customers that purchase an on-premises Office 2016 suite through Volume Licensing before August 1, 2016 will be exempt from the Software Assurance requirement through August 1, 2019. For more information on licensing requirements, please refer to our Product Terms.

  1. Why Microsoft employee cannot download OOS?

    • We are not seeing on the Volume Licensing Service Center yet? I can download a language package and that is it. That does not make a lot of sense…

      • The item is available now. You have to go and find Office Pro 2016 and Office Online is listed under the Office 2016 Pro suite.

  2. Will MSDN subscriber also be able to download OOS? Trial downloads?

    • I would assume so since the language packs and previous web apps are available

    • We were told no, it will not be on MSDN.. .I find it crazy since the Lang pack is there, but they said the software would not be there. We have been fighting this for a few months when we found out.

      • Because OOS is tied to an Office client license (Office Standard, Office Professional Plus, Office for Mac Standard, or Office 365 ProPlus), the OOS software will be associated with the relevant client license on VLSC. The OOS software will be available on MSDN beginning May 9, 2016.

        • will be the “OOS Software” (fka Office Web Apps Server) available on MSDN today?
          maybe I’m a little bit to early … since it’s 9th of May but not yet 6:00 am Central Time 🙂

          • I’m still not seeing it, and it’s after 16:00 here in Europe. Did they hide it under a different name?

    • Because OOS is tied to an Office client license (Office Standard, Office Professional Plus, Office for Mac Standard, or Office 365 ProPlus), the OOS software will be associated with the relevant client license on VLSC. The OOS software will be available on MSDN beginning May 9, 2016.

  3. What’s happened with previous releases like Office Web Apps 2013 installed in our farms, there’s an upgrade patch or something like that … ¿?

    • No, this is a new dev product. OwA does not work with SharePoint 2016 anyways, so you have to do a clean install of the new Office Online Services

  4. Why is there no download for MSDN customers, other than the language pack? Is it coming? We need to prototype OOS in our labs.

    • Product Key & Language Packs are in MSDN

      Server Download is missing, will it come?

  5. The Office Online Server download can be found under the Office Professional Plus 2016 64-bit download in the VLSC.

    • Nick, we cannot find it either.. Do we have to click “Download” on the Office Pro Plus 2016 first, and then we can see it? We do not see it in the list

      • Nevermind, we found it. not sure why you have to click download on the Office pro plus first, but whatever.. its downloading

        • Thanks David, but at VLSC : I get the Office Pro Plus 2016 (OPP2016) installer if I click the download button, I do not any option listed for Office Online Server (OOS). Appreciate if you can help me identify if am missing anything obvious.

          Thanks in advance

  6. Can someone from the Office team answer the WHY question the rest of us are asking? Why VLC distro? How do we create demonstrations and test when we don’t have access to the bits? I’d love to include OOS in a demo rig like I have with OWA, but cannot because I don’t have access to the VLC. My clients would like to try before they move forward, but won’t unless they can download OOS (from MSDN) and then test it in their environments. Sure I could ask a guy, who knows a guy and get an unofficial copy, but I am asking for someone to make sense of this.

    • I agree.. I know we have talked about this in that Yammer channel you and I belong to. I hope they change there mind. I am having to have someone else look for this for me, and they cannot find it. Just wish it was on MSDN

    • Because OOS is tied to an Office client license (Office Standard, Office Professional Plus, Office for Mac Standard, or Office 365 ProPlus), the OOS software will be associated with the relevant client license on VLSC. The OOS software will be available on MSDN beginning May 9, 2016.

  7. Is it possible to link Office Online Server to existing network file shares? So, people can edit documents, spreadsheets, and presentations that are stored on network file shares without copying them to a SharePoint document library?

    • You can use Avepoint Connector to bring fileshares into SharePoint.

  8. The article says that it is backwards compatible with 2013, but all of the scenarios talk about integration with 2016 products. Are ALL features compatible with 2013? Or is there an article somewhere that tells you which features work with 2013 and which features require 2016?

  9. Can you link Office Online Server to network file shares? Basically, allow editing of Office documents without the need to migrate everything to SharePoint and/or OneDrive.

    • I agree with everyone else I don’t understand why this is not on MSDN.

      • Because OOS is tied to an Office client license (Office Standard, Office Professional Plus, Office for Mac Standard, or Office 365 ProPlus), the OOS software will be associated with the relevant client license on VLSC. The OOS software will be available on MSDN beginning May 9, 2016.

  10. Shown on MSDN as available but when trying to download only the language pack shows up, …
    Why making MSDN subscibers upset?

    • Now you can download the server from MSDN subscription site. But you can keep upset coz no language pack can be installed successfully onto new Office Online Server.

  11. 🙂 now it’s even available on MSDN: “Office Online Server” or “Office Online Server (Last updated May 2016)”
    Thanks!

  12. Is it possible to work on an Excel file with multiple users at the same time if you have SharePoint 2013 and OOS?

  13. The Product Terms state that any version of Office Standard or Pro Plus installed on the qualifying device grants edit access to documents via Office Online Server. Does that mean that users of a device with a prior-version license can edit documents with the functionality provided by Office Online Server?

    • It states in the article above that Software Assurance is required. So a prior-version Office license is not enough, you’ll need a version of Office that has SA associated with it.

      • The edit/create functionality is listed as being an SA benefit, but the requirement for active SA is deferred until August 2019 so it would appear to be a gray area. Will seek clarification from our reseller.

        • Any update about this problem?
          We have licensed Office Professional Plus 2016 (on premise) on client computer, but can’t edit files through OOS.

  14. Where can I report bugs for OOS?

    For instance:
    Issue: OOS uses 100% CPU after renaming a server machine in the farm, due to several “watchdog” processes repeatedly crashing.
    Resolution (May 2016 version): Execute the New-OfficeWebAppsFarm powershell command again on the renamed server.

    We use a “farm” containing one single server for development purposes. I have downloaded the May 2016 version of OOS using our Visual Studio Enterprise with MSDN (MPN) subscription.
