However today, I figured out i could open a gmail account. On their calendars, I can “link for url” and it pull my work ical file data and sync it with its calendar. Then from there I can then use the gmail calendar settings to share the gmail version back into my Magic Mirror. This fixes the Ms issues and seems to have worked so far for almost a week now straight.

GMail>calender> link to url> (wait for it to sync (mine took about 10min) then share new calender (bottom of page ical)> copy url back into Magic Mirror

Hope this helps some people out there
