SharePoint Recurring Meeting Workspace not available as an option to “Link To” in Outlook

Question

I created a SharePoint Workspace for a recurring meeting in SharePoint. No problem here. When I go into Outlook and try to create an appointment and link it to the Workspace, it is not available as option of a Workspace that can be linked to. I see other Workspaces here, just not the one for the recurring meeting. Any ideas? Is this not possible?

Thanks
