Though Powerapps, I am trying to access other person's Work calendars within our institution. I know this is against the grain as far as permission go within Office365.
The obvious thought is to have each of these calendars set to share. This is not against the Office365 grain, but it does not seem like this is possible yet - "the connection is based on user credentials, so once the connection is added, the app is only available to get data from the mailbox of the corresponding user, there is no way that I am aware of to access other user's Mailbox"

Well here is where my situation differs a bit. Before building it out, I wanted to see if anyone can tell me for sure it won't work.
Through some third party software, the Work calendars for each employee are polled from a practice management database and are written out/updated on the their individual outlook Work calendars. They also are written out to a admin outlook account where their schedules can be seen. In fact making a powerapp logged into this admin account indeed has access to all the calendar data.
I share this app with my personal login, Logout admin, login my personal account, run the app. I get the usual one time permissions request. I click use a different account which seems buggy because I just adds another choice of my personal account. In any event I permit my personal account. Not a surprise, no data available.
So explicitly, Is Powerapps able to see data for a ANOTHER SINGLE PERSON's Calendar data? If so how, and can you think of security implications beyond showing the calendar data?
