2.2.36 [RFC3501] Section 6.4.7, COPY Command

  • Article

V0057:

The specification states: "The flags and internal date of the message(s) SHOULD be preserved, and the \Recent flag SHOULD be set, in the copy."

Microsoft Office Outlook 2007, Microsoft Outlook 2010, Microsoft Outlook 2013, Microsoft Outlook 2016, Microsoft Outlook 2019

Outlook might display the wrong date on the target message if the server does not preserve the flags and internal date of the message(s). Outlook is unaffected by the setting of the \Recent flag.

V0058:

The specification states: "Unless it is certain that the destination mailbox cannot be created, the server MUST send the response code TRYCREATE as the prefix of the text of the tagged NO response."

Office Outlook 2007, Outlook 2010, Outlook 2013, Outlook 2016, Outlook 2019

Outlook ignores the TRYCREATE response code.
