@sdetweil said in Error with Outlook Calendar:

~/MagicMirror/node_modules/node-ical/package.json

its “node-ical@0.12.0”

so with the installcall i get an old version? did a fresh install just 12 hours ago and its still 0.12.0

Had same issues.
had a long search and found the soultion:

get latest version of ical.js and copy/write it to ~/MagicMirror/node_modules/node-ical.ical.js

Link : https://raw.githubusercontent.com/jens-maus/node-ical/master/ical.js

now it works like a charm ;)
