Embeddable calendars NOT Google

[CarlaKAnderson]

My university is currently switching from Google-based email to Outlook, so we can no longer access or edit Google calendars.

In my current program, we have a Google calendar with all the meetings embedded in the Canvas page. Members of the Canvas page are not invited to specific events, they just view the calendar and click on the events they choose to attend. 

Outlook calendar cannot be embedded in Canvas. For security reasons we can't just set up a private gmail account/Google calendar, so I'm trying to find some other online calendar programs that are also compatible with/could be embedded in Canvas. Are there other alternatives out there?
