Outlook 2010: Trying to share a calendar

Our company has Office 2010 installed and we are trying to share a calendar. The main calendar is controlled by the secretary and viewable by others. What I am running into is that the "Share Calendar" and "Calendar Permissions" is greyed out - not sure why or how to UN-grey them.

I have also tried to "Publish Online" and have tried several variations of www.location.com and get no where - when publishing to WebDAV. When I try the Office.com direction, I get a "must register to Office.com first" message.

Anyone have any ideas/suggestions?

Much thanks in advance...

Thank you for your response.
I looked up Outlook Server in my Outlook 2010 for Dummies and do not see anything that relates to that specifically.
As I mentioned, the control buttons for "Share Calendar" and "Calendar Permissions" are greyed out and I cannot figure out why or how to un-grey them.

I am wondering if your comment about an Outlook Server is the following: setup an area (drive/folder) on the Server where a calendar (or calendars) are saved to as an ICS file and from there they are then sharable?

Another thought I've had was to install a version for Outlook 2010 (just that part) onto the Server and go from there in share and granting permissions.

Any thoughts?
