You receive a "Sorry, there was a problem and we can't open this document" error when you try to view an Office document in Office Web Apps

You receive a "Sorry, there was a problem and we can’t open this document" error when you try to view an Office document in Office Web Apps and the primary reason for the behaviour are the following settings

  1. AllowOAuthOverHttp setting is set to False (It should be set to True)
  2. The SharePoint host domain is not in the allow list. Use the New-OfficeWebAppsHost command to add the domain to the allow list

However, you might also see the same error when your OWA server is not able to communicate with the SharePoint server. Check that both SharePoint and the OWA server are able to communicate with each other. Also see http://www.dhirendrayadav.com/2014/01/you-receive-this-document-cant-be.html

You receive a "Sorry, this document can’t be opened for editing" error when you try to edit a Word document in Office Web Apps

You receive a "Sorry, this document can’t be opened for editing" error when you try to edit an Office document in Office Web Apps and the primarily the reason is UPA not synced correctly with Active Directory User groups as described here. http://support.microsoft.com/kb/2908321 However, I want to bring one more aspect where editing word documents was not working in my SharePoint environment and was failing withe the same message “Sorry, this document can’t be opened for editing” and it turned out that I had disabled co-authoring on my web application which led to this behaviour. Make sure that co-authoring is enabled and you will not get this error while editing in office web apps. SPWebApplication.DisableCoauthoring = false;
