We currently have Exchange 2010 SP3 installed in our organisation for staff mailboxes and also a Office 365 setup for our students. We have some standard domains and one federated domain on Office 365 and one on-premise domain. We have a Exchange 2010 Hybrid setup to share with Office 365 and initially set up for free/busy sharing. Now we'd like to have full calendar sharing for staff (but not students).
Any ideas where and what to configure?
