Subject: [Imap-protocol] UID MOVE and untagged OKs
In-Reply-To: <25069F83-83C9-4130-B0D0-6C4FCC37A292@jabberwocky.com>

Office 365 is being totally bogus here. An untagged OK is "* OK " stuff CRLF.
a01 UID MOVE 1 INBOX.Archive
* OK [COPYUID 1400482663 1 1] Completed
* 1 EXPUNGE
a01 OK Completed
From a real live server (Cyrus IMAPd) right now.
Response lines in IMAP _always_ either start with '*' if they're an untagged response, or a tag.
2.2.2. Server Protocol Sender and Client Protocol Receiver
Data transmitted by the server to the client and status responses
that do not indicate command completion are prefixed with the token
"*", and are called untagged responses.
If the line doesn't start with '*' or a tag for a command that you have already sent in this connection, that is a server bug (modulo continuation lines which start with '+' or data within a literal of course).

There is no untagged OK / "* OK" there, which seems incorrect to me and perhaps more significantly, seems to cause the Apple iOS mail program to throw an error every time a message is moved from folder to folder (which of course includes the "delete this message" function).

The most recent response insists that they are following the RFC, and in fact quoted the "Servers implementing UIDPLUS are also advised to send the COPYUID response code in an untagged OK before sending EXPUNGE or moved responses." line from RFC-6851 as what they are doing.
