Microsoft Exchange Server 2007 RFC and Support for Standards

 

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.

importantImportant:
The information contained in this topic represents the current view of Microsoft Corporation on the issues discussed as of the date of publication. Because Microsoft must respond to changing market conditions, it should not be interpreted to be a commitment on the part of Microsoft, and Microsoft cannot guarantee the accuracy of any information that is presented in this topic after the date of publication.
This topic is for informational purposes only. MICROSOFT MAKES NO WARRANTIES, EXPRESS OR IMPLIED, AS TO THE INFORMATION IN THIS DOCUMENT.

All document references are listed in the following format:

 

Document/RFC: Document or RFC index.

Title: Description or title of document.

Updated by: RFCs that update this document.

Updates: RFCs updated by this document.

Obsoletes: RFCs replaced by this document or obsolete.

Exchange 2007 specific: Implemented or supported by Exchange 2007; if applicable, the component and any other notes about support for the applicable RFC; links to additional information.

noteNote:
For the purposes of this topic, "implemented" means that the RFC has been implemented natively within Exchange 2007, and "supported" means that a technology outside of Exchange 2007 has implemented the RFC but that Exchange 2007 uses that implementation.

Not all document references contain all fields that are shown in the sample format. In some cases, the information has been consolidated. Refer to the document source for the latest information.
