Consider the following scenario:
You migrate from Microsoft Exchange Server 2010 to Exchange Server 2013.
You have a forwarding rule that was created by the Folder Assistant for a public folder.
The forwarding rule uses the "Leave message intact" method.
In this scenario, if an email message is received from an external sender, the message is not forwarded.
This issue occurs because the Send-As permission is evaluated incorrectly.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
