I'm trying to share an exchange calendar with all users on our network.
Our network is running Exchange 2010. I have tried to share the calendar with a distribution group called "All Staff," which e-mails all users on the network, but I get this error message:
"Calendar sharing is not available with the following entries because of permission settings on your network."
I also want to share this calendar with an external contact, but am getting the same message.
Where can I go in Exchange 2010 to change my network's permission settings?
