We have Exchange 2007 with about 100 users. I would like to change everyone's free/busy permissions to grant Reviewer status to a specific AD group.
I have tried PFDAVAdmin tool but when I commit any changes, they do not affect the users. If I grant myself Reviewer permissions to another user's calendar using the tool, I still cannot view that user's free/busy details, and I also don't show up on the list of people with permissions on that user's Outlook calendar options.
It seems like PFDAVAdmin simply appears to do something, but doesn't actually change anything. Is there any other way for me to accomplish what I need to do? Or is there something I may not be doing right with PFDAVAdmin?
FYI I have followed directions from this link: http://exchangeshare.wordpress.com/2008/05/27/faq-give-calendar-read-permission-on-all-mailboxes-pfdavadmin/
