PFDAVADMIN is a great tool to set calendar permissions for all users in a organization in an Exchange 2003 or Exchange 2007 environment. I.e. you can set Read permissions for everyone in your organization, so everyone can view each other’s appointments.
PFDAVADMIN has the option Set Calendar Permission in the Tools menu.
However, this option only works when you’re using English-languaged mailboxes. This is because the calendar must be named Calendar. When using another language, the calendar may be named differently. Like Kalendar (Swedish) or Agenda (Dutch).
