I am able to export my Canvas calendar TO Outlook, but can I import or sync FROM my Outlook calendar to Canvas?
I believe that Canvas does not currently have the ability to import calendars. But there are some ideas on the idea forum that you can vote on. Outlook can export as an ICS so these ideas should help you as well as those using Google Calendar.
Import calendar from ICS file
Please Allow Us to Import FROM Google Calendar INTO Canvas Calendar
