Does not work Web Office Apps for SharePoint 2010

April 27, 2011

Today I got some problem with opening word documents in SharePoint 2010.




Word Web App cannot open this document for viewing because of an unexpected error. To view this document, open it in Microsoft Word.

There are a number of basic things to check immediately but none of them seemed to solve our problem.

ULS logs:


a6ecac4b85890f990f6b262c55m0846e19754004739ad93720821134224m, Silverlight, docdata.xml) – status = ConversionError

So the Word Viewing Service Application is having trouble converting the document into Silverlight to send to the client.

Resolve problem:

$e = Get-SPServiceApplication | where {$_.TypeName.Equals("Word Viewing Service Application")}


$e.WordServerIsSandboxed = $false



Also if you use SharePoint 2010 on DC,  you have to write this code:

#(Please use the below script for PowerPointServiceApplication – You need to enter "Y" for the answer of each cmd)
Get-SPPowerPointServiceApplication | Set-SPPowerPointServiceApplication -EnableSandboxedViewing $false
Get-SPPowerPointServiceApplication | Set-SPPowerPointServiceApplication -EnableSandboxedEditing $false


After you can to go to the path c:\windows\system32\inetsrv\config\applicationHost.config

and add dynamicTypes tag:

<add mimeType="application/zip" enabled="false" />
