For better or worse, this is a known issue. I'm not aware of any schedule for correction.
Move the calendar to the root calendar of a shared mailbox; is the approved workaround. From: Eric [mailto:[email protected]] Sent: Thursday, April 11, 2013 4:39 PM To: MS-Exchange Admin Issues Subject: Slightly OT - Outlook 2011 Accessing Shared Sub Folder Calendars Sorry for the OT post, but I've posted this to Technet and been searching all morning for a solution. We are a mixed Windows and Mac environment. I have a user who has created a sub folder - calendar which she has shared. The people who are using Outlook 2010 on Windows can access the shared calendar just fine. Users running Outlook 2011 on Macs cannot access the shared calendar. The sharing invitation includes an xml attachment that Outlook 2011 cannot process. Any suggestions for getting access to this shared sub folder calendar would be appreciated.
