We have several users that cannot see the free/busy information of another user in their Outlook 2013 calendars. Creating a new Outlook profile for the user and repairing office solves the issue for a short period of time. Users are running Windows 8 64 bit, Windows 7 32bit and 64bit with Office 2013. Our Exchange server is 2010 version 14.03.0158.001. I have included screenshots of the issue.
