Sharing Calendars - Delegates

[Guest]

When sharing a calendar... I must do it from the Office Tools > Options > Delegates dialogues instead of simply clicking on Share my calendar in the Navigation Pane as my colleagues are able to do. Have I missed a setting of some sort. When I click on Share my calendar.... a dialogue box opens with four tabs. "General" "Home Page" "AutoArchive""Synchoronization" I do not see what my colleagues see... which is a tab that includes "Permissions

Can anyone enlighten me on what Frieght Train sized option I've overlooked in my search to correct this
