Shared calendar on macOS Calendar app

We discovered that the Mac OS X app was requesting hidden folders when fetching list of calendars. The new shared calendars are stored as hidden folders and were supposed to be only visible in EAS & REST APIs, but we weren't explicitly excluding them from apps that requested hidden folders.

While they showed up in the EWS app, full functionality was never supported via EWS so it's possible that edits would fail, for example.

I've submitted a request to our support writers to update the calendar sharing support article, but most of them are out of town on vacation for the holidays. I'm hoping our documentation is updated in early January to reflect this.

Also, please feel free to private message me with more details on why your users want to use Mac OS X instead of Outlook for Mac - I'm curious what the deltas are.
