How to view a send as permission for a public folder

Try the following

I don't see the send as permission for the public folder.

Whait is the exactly command?

Sorry that was for 2010

Get-PublicFolder -Identity -recurse -Server servername | Get-PublicFolderClientPermission -server servername > c:non_extended_pflist.txt

I did that :
Get-PublicFolder -Identity "\Dossiers spéciaux\Solution Mcafee" -Server 'Epervier' | Get-PublicFolderClientPermission -server 'Epervier'

The result display just the AccessRights, not the Send As permission.

Because it's the solution.
