Are there any tools that allow you to subscribe to an ICS feed in Office 365, but in reality, SYNCHRONIZE that feed to a secondary O365 calendar?
Use case: I've got my main calendar which I maintain. I'm also subscribed to my 'teaching calendar' which changes occasionally, outside my control. When someone wants to schedule a meeting with me from within my organization, I would like them to know that I am not available during my teaching periods. If events get added, removed, or updated in the subscribed calendar, those changes must be reflected in the 'real' calendar.
I would imagine that there might be a cloud service or sync widget out there somewhere that you could provide your O365 credentials and the ICS URL and it would 'do the magic' -- but can't seem to find anything like this.
