Add Options to Configure Office 365 Add-In During Installation

Question

I'm currently writing an updated version of my company's PowerPoint add-in for 365. In previous versions of PowerPoint we've been able to store global settings in configuration files which allow managers to distribute the application across their institutions pre-configured. Because of the way our add-in works, it wouldn't be remotely practical for every end user to have to enter these settings themselves.

I've been scouring the internet for hours for an answer, and the closest I could find was the following SO question from 16 months ago where someone claims that it wasn't possible at the time:

Office Add-In with configurable options during installation?

Does anybody know if this is achievable now? Given that Microsoft have made it so easy to distribute an add-in to everyone in a group, it seems like a massive oversight to not allow any sort of configuration before that happens.

Answer 1

I'm afraid that this still isn't possible.
