Perhaps this has been answered somewhere deep in the archives, but I haven't been able to find the solution/recommendation, so here goes:
1. What is the most efficient way to globally share all users' calendars as read-only to all other users?
From what I can tell, to do this globally, I would need to script out the changes as:
a) create a new read-only share for each user's calendar
b) subscribe all users to each shared calendar
2. I suspect this will require each user to accept the share manually. Is there a way to suppress the new share notifications and have the new share automagically accepted?
3. If anyone is globally sharing all users' calendars, have you seen any significant performance hits in the webgui or Outlook synchronization?
Thanks for any tips or direction.
