I use Outlook 2010 on 4 different computers. On each of them, I subscribe to several of my Google calendars by adding the ICS addresses of those calendars. The problem I'm experiencing is that, if I remove an internet calendar from one of my 4 computers (right-click, delete), it is removed from all 4 computers as well! This is not the behavior that I expected or wanted - I just want to remove the calendar from that one computer but have it remain on the others. When I delete an internet (Google) calendar on a computer, Outlook warns that "Deleting this folder removes the related Internet Calendar from all computers that you use.", but I did not take that seriously as I could not imagine that Outlook on one of my computers could communicate with Outlook on my other 3 computers. Does anyone know what's going on and how I can delete an internet (Google) calendar in Outlook on one of my computers without affecting the other 3 computers?
