Purpose

Outlook for Mac 2011/2016 Clients do not have the ability to subscribe to an internet calendar. This prevents users from being able to add their Confluence Team Calendars into the Client and view it without needing to log into Confluence.

Solution

If you have access to Outlook Web Access (OWA), you can open an Internet Calendar, like a Confluence Team Calendars, and have it appear in the Outlook client application.
