After the update to Core Agent 2.20.4, any Office 365 app that creates a lock file are crashing when they exit. Once Sophos is uninstalled, the crashing stops. If you create a new document, it doesn't crash, but if you open an existing document and the lock file is created, the app will crash when you exit. Changes are saved, however. It seems that Sophos is having a problem when that lock file is deleted. This is happening so far to Excel, Word, and Access.
