Consider the following scenario in a mixed Microsoft Exchange Server 2010 and Exchange Server 2007 environment:
- You have a resource mailbox that is located on an Exchange Server 2007 server.
- Public folder replication occurs between the Exchange Server 2007 server and an Exchange Server 2010.
- A user sends a meeting request to the resource mailbox by using Outlook Web App (OWA).
This issue occurs because the Microsoft Exchange System Attendant service (Mad.exe) cannot publish or update free/busy information to an Exchange Server 2010 public folder.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
