“Share Calendar” button greyed out in Outlook 2010

Question

I´m trying to share a calendar using Outlook 2010 but the button is greyed out.

I can share it without problems if I use Outlook 2007

I´m running Outlook 2010 against a 2003 Exchange server.

How can I share it using 2010 version

You should check inheritance is checked under the security properties of the user (in AD).

Also check full permission given on that mailbox to 'Self'.
