Hi Guys I have created a room mailbox in Exchange 2007 I have used the command Add-MailboxPermission "RoomMailbox" -userusername -AccessRights FullAccess What is the command to view the permissions against the mailbox and how can I give permissions to everyone who is associated to my Domain? Thanks

I just tried this and it seems to work Add-MailboxPermission "RoomMailbox" -user"Authenicated Users" -AccessRights FullAccess Do not know if this is best practice, but seemed to work.

Doug Thanks for your help

Hi, you can view the permissions with: Get-MailboxPermission -Identity "<identity of a mailbox>" Of course, you can format the output with Format-List (fl) orFormat-Table (ft).
