Exchange Server and Outlook Standards Support Feedback

  • Article

Microsoft recognizes that in an increasingly interconnected computing landscape, enabling interoperability between products from different vendors is important.  In particular, Microsoft understands that its customers value interoperability with respect to email and calendaring functionality. In addition, in December 2009, Microsoft made a comprehensive commitment to the promotion of interoperability to the European Commission.  In connection with that commitment, Microsoft is soliciting community input regarding its support of the core and most commonly adopted email and calendaring standards in the next versions of Exchange Server and Microsoft Outlook. Exchange Server 2013 and Microsoft Outlook 2013 support the following core and most commonly adopted email and calendaring standards: 

  • IMAP:  Internet Message Access Protocol version 4.1 (RFC 3501)
  • POP3: Post Office Protocol version 3 (RFC 1939)
  • iCalendar:  Internet iCalendar Protocol (RFC 2445), the iCalendar Transport-Independent Interoperability Protocol (RFC 2446), and the iCalendar Message-Based Interoperability Protocol (RFC 2447).

Documentation of that support is publicly available at no charge on MSDN.  Microsoft will continue to support these standards in the next versions of Exchange Server and Microsoft Outlook. 

To provide feedback on additional email or calendaring standards that you would like Microsoft to support in the next versions of Exchange Server and Microsoft Outlook, please click here or send email to emailstand@microsoft.com.  Please do not include confidential information in your feedback; feedback will be not be treated as confidential.  After 90-days, Microsoft will consider all of the feedback provided and post a general response in this forum.   Thank you, in advance, for your input.
