My office IT prevents me from saving an ics file on my computer (at least I can figure out how to do that), but i am able to email myself a calendar at my Gmail address. I open the mail message and see the mail attachment, but I can't find any add to calendar options, or other means to get this file into Google Calendar. My office IT also prevents download and installation of add-ons that might help. If there is something already posted that addresses this, I have missed it. Any help would be appreciated, but again, download of additional tools is not an option. Help?
