title: Is there a detailed specification for Outlook 365 IMAP? Which RFC's does it comply with?
body: <p>Does anyone know if there is a specification for Outlook 365 that would describe their IMAP implementation in detail.</p>
  <p>In particular, Which RFC's they comply with.  For example, there are many Updates to RFC 3501.  RFC 3501 list these RFC's in the update section. 466, 4469, 4551, 5032, 5182, 5738,6186, 6858, 7817, 8314, 8437, 8474</p>
  <p>In addition, I'm having problems with how Outlook manages IMAP folder's. Outlook is sending the LIST command but not the LSUB command.  LSUB is only send manually if the IMAP Folders outlook option is used. This is different from how other IMAP clients work.</p>
