https://outlook.office.com/calendar/0/deeplink/compose - fails to load and redirect

I can confirm I'm having the same issue.

Edit: Thank you snapper88 for referring to the discussion on github! Following that I could get it to work replacing the word deeplink with "action" in the url.

Don't know if this is meant to stay this way or why it was changed in the first place. I couldn't find any statement by Microsoft on this.
