Exchange 2013 - ECP shows wrong public folder permissions

Hi everybody,

I just migrated from Exchange 2007 to 2013 SP1 CU7 and we have an issue with the public folder permissions in ECP. ECP doest not show the correct permissions, here an example:

Get-PublicFolder "\Folder" | Get-PublicFolderClientPermission | ft

FolderName               User          AccessRights
----------               ----          ------------
Folder			 Default       {Author}
Folder			 Anonymous     {None}
Folder			 Administrator {Owner}

Clik here to view.

Thank you very much and best regards,

Sebastian
