I'm trying to find out if retention policies can be applied to public folder content in Exchange 2013. I can't seem to find consistent information on this.
In this Exchange 2013 Public Folder FAQ:
http://technet.microsoft.com/en-us/library/jj552408(v=exchg.150).aspx
"Can you set retention policies on public folders?Just like in previous versions of Exchange, you can set retention limits on items."
But in this Public Folder White Paper:
http://technet.microsoft.com/en-us/library/jj150538(v=exchg.150).aspx
"Retention policies aren’t supported for public folder mailboxes."
