Exchange 2010 Support for RFC Standards

Exchange 2010
 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Topic Last Modified: 2010-07-27

This topic is intended to be a reference for the Request for Comments (RFC) and other standards that are supported in Microsoft Exchange Server 2010. Although every effort has been made to verify this information, omission of an RFC from this list does not necessarily mean that Exchange does not fully or partially support the RFC. RFCs are guidelines, and they frequently contain two types of information: required and optional. Microsoft and other vendors may choose not to implement optional requirements, or they may interpret sections of RFCs differently.

If you are experiencing a problem that you believe is caused because Exchange does not correctly support a particular RFC, open a support incident through Microsoft Customer Support Services (CSS).

importantImportant:
The information that is contained in this topic represents the current view of Microsoft Corporation about the issues discussed as of the date of publication. Because Microsoft must respond to changing market conditions, this information should not be interpreted to be a commitment on the part of Microsoft. 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 that are updated by this document

Obsoletes: RFCs that are replaced by this document or are obsolete

Exchange 2010 specific: RFCs that are implemented by or supported by Exchange 2010; 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 2010, and "supported" means that a technology that is outside Exchange 2010 has implemented the RFC but that Exchange 2010 uses that implementation.

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