ICloud calendar will not allow delegation

Question

I am trying to share a calendar with my wife who is on another appleid. Following the instructions on the iCalendar Help it said to go to
Calendar-> Preferences & select Accounts.
Then select the calendar account to share which I did.
When I clicked the Delegation tab the window indicated
   The server doesn't support delegation for this account.
Is this some iCloud setting I need to change? Or ...?
I'm fairly new to using iCalendar on a computer (rather than via iOS iTouch).

Answer 1

do you have calendars checked in your icloud preferences?  if not that may be the issue.
also here are the steps for sharing an icloud calendar:
You can give people read-only or read-and-write privileges to shared calendars. They can access your calendars using Calendar (on a Mac with OS X Mountain Lion, iPhone, iPad, and iPod touch), iCloud Calendar at www.icloud.com, iCal (on a Mac with OS X Lion v10.7.2 or later), and Microsoft Outlook.
On OS X Mountain Lion v10.8.2 or later, place the pointer over the calendar’s name, and then click the broadcast icon.Or, click the calendar’s name, and then choose Edit > Share Calendar.If you don’t see your calendars, click Calendars.
Select whether you want the calendar to be private or public.
If you make the calendar private, only the people you invite can see the calendar.To share the calendar with someone, on OS X Mountain Lion v10.8.2 or later, enter the person’s email address (or contact’s name), and then press Return. To change the person’s access privileges, click the triangle next the address (or name), and then choose an option.Or, click Add (+), and then enter the person’s email address. Select the person’s access privileges in the Privilege column.
If you make the calendar public, the calendar is read-only, and anyone with the URL can subscribe to it.To share a public calendar with someone, on OS X Mountain Lion v10.8.2, either enter the person’s email address (or contact’s name) or click the Share button next to the calendar’s URL.Or, hold down the Control key, click the calendar’s name, and then choose Resend Invitations.
Click Done (or Share).
try these steps and should resolve the issue
