I am having an issue with Exchange 2010. I need to change the DEFAULT permission on calendar to Reviewer (in other words grant everyone READ access to everyone's calendars).
I have tried with ExFolder but it doesn't add the GROUP into the ACL. I have tried the Shell script Add/Set-MailboxFolderPermission -Identity Username:\Calendar -user Default -accessrights reviewer
but system says USERNAME does not exist.
Can anyone shed some lights here please?
Another related query is that is it a way to configure Exchange, so going forward everyone has READ access on all new user calendars?
THanks in advance for your help
