When I schedule a meeting with other users on our exchange server I cannot see the Free Busy information on the Scheduling Tab of the Meeting Invite.
I can go into Calendar, Open Shared Calendar and select the same users and see all of their appointments, though just not in the meeting invite.
After I send the Meeting invite and go back into the Meeting Invite I can see the Free Busy info. It just seems to be on the initial Creation of the Meeting Invite.
We are running an Exchange 2010 On-Premise server with a Hybrid Cloud Connector to Office 365. All users have mailboxes on the On-Premise Server.
