All things RMS sharing app ...
If you've been reading the exciting announcements for RMS (blog post Major Update: Improved Office file support + Service improvements) ... and if not, you really should! ... you will know that updating the RMS sharing app played a major role in the recent releases. I loved the walkthrough and screenshots in the blog post, but if you're looking for more information, we've just published an "all things RMS sharing app" page: https://curah.microsoft.com/191031/how-rms-protects-all-file-types-by-using-the-rms-sharing-app
Let me know if you have any feedback about this new page!
