A user told me that they were no longer able to edit word documents in the Extranet. This was not an issue in the past but seems to be a new problem since Office Web Apps has been installed. The option to Edit in Word was no longer available.
When the user tried to Edit in Browser they recieved "This document cannot be opened for editing" error.
A check in the ULS logs found this error but it didn't shed much light.
I tried to Edit the same file internally and this opened without any issue which prompted me to check the settings in Authentication Providers. To get there open your Central Administration site, and then click on Manage Web Applications. Then highlight the affected site and click on Authentication Providers in the ribbon.
Choose the zone that is causing problems and scroll to the end to check the Client Integration setting. If this is set to No you can set it to Yes. Note that this will allow the user to edit in Word but they may have to enter their credentials twice. Once this has been updated check your Extranet again to see if Edit in Word is now available.
