Hello, I need to be able to assign either fullaccess or calendar access permissions to an Active Directory security group so that users within that group can view a resource mailbox's calendar easily. I have tried using the Add-MailboxPermission command and it worked fine for an individual user, but appears to not work for Active Directory groups. I know that you can assign these permissions, as I have done it through Outlook 2007. Is there a way to set this permission up through the management shell or elsewhere? I see finding an efficient manner of doing this fairly important. Thank you, NL

Here is the command line. Add-MailboxPermission[Mailbox] -User:"[Group]"-AccessRights:FullAccess I

Hello! good question - i have the same problem. But i wouldn't like to grant "fullaccess" to the complete mailbox. I would like to permit a AD-user-group just to the calendar and contact-data. Is ist possible with the powershell-command? Thanks a lot Andi
