Consider the following scenario:
- You install Microsoft Exchange Server 2010 Service Pack 1 (SP1) on an Exchange Server 2010 Hub Transport server.
- The Hub Transport server processes an item that contains an invalid charset. For example, the content-type header is set to the following:
Content-Type: text/html; charset="windows-1252http-equivContent-Type"
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
