Users provided access to SharePoint through Active Directory (AD) Security Groups may not able to edit documents via the browser using Office Online (OWA) without error.

In this scenario, the error from the Word App is: "Sorry, this document can't be opened for editing.”

We may find the following information after analyzing the ULS logs from the Office web apps Server and SharePoint Server.

From Office web apps server:

From SharePoint:

This issue can occur if the User Profile Application (UPA) is out of sync. If a user profile and the relevant group memberships for the user are not synchronized, SharePoint Server 2013 may incorrectly deny access to a given resource.


To resolve this issue ensure the User Profile Service Application (UPA) is properly configured and fully synchronized with user and group memberships.
