Topic Last Modified: 2009-04-29
This topic is intended to be a reference for the Request for Comments (RFC) and other standards that are supported in Microsoft Exchange Server 2007. While every effort has been made to verify this information, omission of an RFC from this list does not necessarily mean that Exchange does not at least partially support the RFC. RFCs are guidelines, but often contain two types of information: required and optional. Microsoft and other vendors may or may not choose to implement optional requirements or may interpret portions of RFCs differently.
If you have an issue where you feel that Exchange is not properly supporting a particular RFC, and this is causing a problem, open a support incident with Microsoft Product Support Services.
