Microsoft Office 2016 15.39
Microsoft has published version 15.39 of its Office 2016 application suite, improving the Visual Basic Editor in Word, Excel, and PowerPoint. You can now create and edit macros in the Visual Basic Editor using IntelliSense, VBA menus and toolbars, debug tools, an object browser, and more. The update also resolves an important vulnerability that could expose you to remote code execution. ($149.99 for one-time purchase, free update through Microsoft AutoUpdate, release notes, 10.10+)
I have been unable to update my Microsoft 365 apps using the Microsoft UpDater in elCapitan. The Microsoft updater appears to work on my MacBook Pro running High Sierra.
