Slate External iCal Integration for Outlook

Slate allows users to add external iCal feeds into Slate Events and Scheduler. Users can easily add institutional calendars, staff calendars and more, directly into Slate including any free/busy information.


When adding a web calendar, it will be added to both the Events and Scheduler calendars; these cannot be separated. iCal subscriptions from/to Slate will be updated every hour.

The US Holiday iCal is automatically available in Slate. If there is a need for a specific iCal, search for the URL here

Adding Events to an Individual Outlook Calendar

  1. Click Events or Scheduler in the top navigation bar.
  2. Select the iCal subscribe section on the lower right-hand side.

  4. In the popup window, click Open Pick an app.
  5. Select Outlook.
  6. In the Outlook Calendar, click Yes in the popup window.

After following these steps, the Slate iCal will sync with the individual Outlook calendar on that user's computer.

Note: According to Microsoft: "Support for importing and synchronizing for iCal is not yet available in Outlook for Mac."
