Download ICS File | Communifire Documentation

It appears that when opening this with .ICS file with Outlook it does not render the HTML tags properly.  Please advise.

There is a time zone problem that shows up if downloading the ICS file while not logged into Communifire. If you're not logged in, the resulting calendar event in Outlook/Google/etc. is wrong. We have a space that is visible to the public, and events are included in the space.

If you are not logged into Communifire, this is an example of the top of the ICS file:

BEGIN:VCALENDAR
VERSION:2.0
METHOD:REQUEST
PRODID:-//Communifire//Calendar
BEGIN:VEVENT
UID:CFEVT-1541@navteams
CLASS:PUBLIC
STATUS:CONFIRMED
DTSTAMP:20201109T163342Z
DTSTART:20201113T210000
DTEND:20201113T220000
ORGANIZER;CN=Staff Editor:MAILTO:(organizer email address)
SUMMARY:(event title)

Whereas once you are logged into the site, you get a bunch of additional fields which clarifies the time zone:

BEGIN:VCALENDAR
VERSION:2.0
METHOD:REQUEST
PRODID:-//Communifire//Calendar
BEGIN:VTIMEZONE
TZID:Mountain Standard Time

Anything we can switch on our system to fix this issue?
