Consider the following scenario:
- You configure the FarmOU property in Office Online Server.
- You set the FarmOU property value to any non-empty string.
- You try to load any Word document in edit mode in Word Online.
In this scenario, you receive a "Sorry…" error message.
This is a product defect specific to the November 2016 release of Office Online Server. It will be fixed in the upcoming release of Office Online Server.
To work around this issue, leave the FarmOU property as an empty string ("").
To do this, run the following PowerShell command on the Office Online Server:
Set-OfficeWebAppsFarm -FarmOU ""
