When you try to check out and edit a PowerPoint 2016 file in the Office 2016 desktop client and the file is stored on a SharePoint document library, PowerPoint says it's a read-only file.
This issue is now fixed in build 6965.2092 or later for Office 2016 who have the Click-to-Run version installed. Office 365 subscribers will see version 1605 (Build 6965.2092) and Office 2016 non-subscribers will see build 16.0.6965.2082. To get the latest updates, click File > Account > Update Options > Update Now.
The fix is in progress for those who have volume license editions of Office 2016, such as Microsoft Office Professional Plus and Microsoft Office Standard, who receive updates through the Windows Installer technology (MSI).
