Verifying the Site Collection Features Are Enabled for Office Web Apps

Assuming the previous steps were followed and the Office Web Apps installed, the site collection features need to be reviewed to make sure the appropriate ones are enabled. Follow these steps to verify that the feature is enabled on site collection where the Office Web Apps feature will be used:

1. Navigate to the site settings page for the site collection that houses the documents that will be accessed via Office Web Apps using an account that is a site collection administrator.
2. In the Site Collection Administrator section, click Site Collection Features.
3. Locate the Office Web Apps entry and click the Activate button.
4. Test that viewing Word, Excel, PowerPoint, and OneNote documents in the browser and editing in the browser is functioning properly.
5. If the functionality is not working properly, check the settings for the document library and default behavior in Central Administration covered in the next two sections.
