We are trying to setup a shared calendar on an Exchange 2010. A message comes up that says:
"The Calendar was shared with some of the recipients. However, calendar sharing is not available wit the following entries because of permission settings on your network."
It lists about 5 addresses on the same domain as the Exchange and asks if you want to send them a copy of the calendar in an email message instead?
How can I resolve this so that she can share this calendar?
