If your screen looks identical to the attachment, Calendar Integration is enabled and should remain as such if you wish to change your call handling mode when in a meeting etc. Now it is recommended you modify your work hours in Microsoft Outlook.
From Outlook, open up your Calendar and Right Click on any date, as seen in Attachment 3 and select “Calendar Options”
