Word Web App cannot open this document due to an unknown error. If the problem persists, try opening the file in Microsoft Word.

After the SharePoint administrator has installed, configured, and activated Office Web Apps, end users might receive an error message when they try to view or edit Microsoft Word, Microsoft Excel, Microsoft PowerPoint, or Microsoft OneNote documents in the browser.


These errors might occur for one or more of the following reasons: (Microsoft recommendations)

  • The SharePoint administrator has run Office Web Apps Setup, which configures the default open behavior for SharePoint to open Microsoft Word, Excel, PowerPoint, and OneNote documents in the browser by using their associated Web application. However, the SharePoint administrator has not yet started the services, created the service applications, and activated the Office Web Apps feature.
  • The Office Web Apps services are not started on the Web front-end server.
  • The Office Web Apps service applications and proxies have not been created.
  • The Office Web Apps service applications proxies are not associated with the proxy group of the Web application that the site collection belongs to.
  • There might be a problem with the permissions for the service account that is used to run the Web application or one of the Office Web Apps services: Excel Calculation Services, PowerPoint Service, or Word Viewing Service. The Web application and service applications must have the appropriate permissions to access the content databases and the configuration database.
Resolution:

  • The SharePoint administrator can avoid end users' seeing error messages while he or she finishes additional deployment tasks to deploy Office Web Apps on a live production server. We recommended that you enable the OpenInClient feature on existing site collections before you run Setup.
  • Activate the Office Web Apps feature for the site collection. For information about how to activate the Office Web Apps feature for a site collection.

  • How to verify that the services has been properly created or not / How to check the status of the services on the servers in the farm:
  • On the Central Administration Web site, in Application Management, click Manage services on server.
  • On the Services on Server page, do the following:

    1. In the list of services on the selected server, verify that Excel Calculation ServicesPowerPoint Service, and Word Viewing Service exist and are started. If a service is not started, click Start.
    2. Click the Server button at the top, click Change Server, and then in the Select Server dialog box, click a different server name.
    3. Repeat these steps until you have verified that the services exist and are started on all servers in the farm.
    Verify that the Office Web Apps service applications and proxies have been created by doing the following:
    1. On the Central Administration Web site, in Application Management, click Manage service applications.
    2. On the Manage Service Applications page, verify that there the following kinds of service applications exist:
      • Excel Services Application Web service application
      • PowerPoint service application
      • Word Viewing service application
    Verify that the Office Web Apps service applications and proxies are associated with the proxy group of the Web application that the site collection belongs to by doing the following:
    1. On the Central Administration Web site, in Application Management, click Manage web applications.
    2. On the Web Applications Management page, select the Web applications that the site collection belongs to, and then clickService Connections.
    3. On the Configure Service Application Associations page, verify that the following kinds of service application proxies are associated with the Web application:
      • Excel Services Application Web service application proxy

      1. Hello Surya,

        are excel and powerpoint working fine? problem is with the word only ?- pls confirm.

        Two main suspects i am thinking right now:

        -does the account has sufficient rights on SQL that you have used to create the word service application ? becoz it should have DB-CREATOR. pls check n confirm.

        -Make sure the Service Account you are using for the Application Pool that is running the Services (Word Viewing Service, etc.) has permission to the Content Database.

        Here is the way by which u can check this(Open SQL management studio, connect to the SQL instance which sharepoint uses, expand logins, double click on the logins for the Application pools which the Word Viewing Service Application and Powerpoint service application use, go to user mappings, check the checkboxes next to your content databases and then check dbo as the permissions)

    11. Hi Amol,

      thanks in advance

      1. - Make sure you are using the account which are having farm admin permissions...
        - or you can use that account which has been used for the installation purpose.

      1. Try to start the service application again and wait till the time it gets stopped.

        check the event viewer and SP logs at the same time. please share it here so that we can analyse.

        I am pretty much sure that we will get something by means of logs.

    13. Hi Amol,
      I have this issue and I tried all the above solutions without any progress.
      In the log file I can find the meaning such as "status = ConversionError", "Conversion response received: CantFindSourceDocument" and "DocumentOutputNotFound". The application pool account has dbo. I have restarted the Word viewing service application several times. I have even restarted the IIS.
      Any new idea or suggestion will be very appreciated

      Thanks!

    15. Hello,

      I've tried everything I can think of and I'm still getting conversion errors in my ULS logs. The crazy thing is it's just the word web app that is having problems. Here is the crazy part...if I select the option to edit a word document in the web browser then the document opens up fine. If I just try to open the word document to view it I get the error message.

      Hopefully you can help!

      1. Once you open the word document in browser then it will use the OWA functionality.

        and when you try to open the document directly then it will use the installed client functionality.

        Could you please convey me which SharePoint Version and Office version you are using? - By this answer i will check the compatibility.

    17. Hi Amol,

      Few things to check: OWA must be installed on each SharePoint Server within the Farm, apart from the SQL Server. Once binaries have been installed run the product configuration wizard. Next activate the feature for OWA at the Site Collection level and test to see if you are able to open Microsoft Office documents via the browser. Running the SP products configuration wizard is a step that must not be missed.
