Office Web Applications Error

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

Problem : This error usually occurs when you have not configured the service applications after you have installed the office web application package on your SharePoint Farm.

Resolution : Log into your SharePoint Central Administration site, navigate to your service application pages and create a service application for Word, PowerPoint and Excel. Once complete perform a IISRESET (not necessary) and try and re-open your document using Office Web Applications.

I hope this resolution has worked for you as it worked for me.


  1. This valuable editorial was very useful to read, I savored it completely.
    I'm about now to email it to my colleagues to permit them examine this too.
    Thank you really

  2. This was absolutely brilliant. I have spent over two days trudging through various articles etc and can't believe it was this simple.
