We do not want users to publish our public calendar's is there a way in Exchange 07 to stop the calendar from being published? I have not found anything on microsofts site.

Perhaps the tool called PFDAV Admin might help you...http://www.microsoft.com/downloads/details.aspx?familyid=635be792-d8ad-49e3-ada4-e2422c0ab424&displaylang=enit can globally set permissions on public folders, so you could set them to be hidden or what have you...

Hello,You need to change the permission of Default or Everyone to None on PF which will stop publishing/displaying it to all users except who has Reviewer or higher permission individually.You can change PF client permission in Outlook by going to PF properties, with PFDavAdmin or withRemove-PublicFolderClientPermission/Add-PublicFolderClientPermission powershell cmdlets.Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
