Hello, I'm using Shell to setup managed folder mailbox policy on a large number of mailboxes. When i specify something on the lines of below for a single user i get an error: Set-mailbox user@domain.com -managedFolderMailboxPolicy "My policy" -ManagedFolderMailboxPolicyAllowed A positional parameter cannot be found that accepts argument '-ManagedFolderMailboxPolicyAllowed' . + CategoryInfo : InvalidArgument: (:) [Set-Mailbox], ParameterBindingException + FullyQualifiedErrorId : PositionalParameterNotFound,Set-Mailbox Specifying the above switch as -ManagedFolderMailboxPolicyAllowed:$True does not help either. I'm sure there is somethign very basic i may be missing, any help is greatly appreciated. Thanks! 

Make sure you are adding the user name correctly. Or use Set-Mailbox -Identity.

Thank you for your reply. I have verified user name and have tried Set-Mailbox -identity as well. If i remove "-ManagedFolderMailboxPolicyAllowed" switch, it works however of course throws the confirmation dialog which i wanna avoid. That however proves that the username or identity parameter i'm passing is accurate. Thanks
