Please note that the time zone for the event will reflect the time zone of the account where it was created. For example if the event started at 5.00pm in a New York account (GMT-5.00) and a recipient opened this link in London (GMT), then the event would start at 10.00pm (GMT).
iCal files enable the recipient to save meetings/event information directly to their email client calendar. It is compatible with Google Calendar, Apple Calendar, Lotus Notes and Outlook.
Click Create Link > Other > iCalendar
Once the link is clicked and the file opened, details that can be saved include: (meetings/event) Title, Location, Start Date/Time, End Date/Time, (meetings/event) Description.
