Fetch error: Error: The specified message set is invalid. !!

I am trying the following code to fetch Hotmail/outlook emails :

var Imap = require("imap"),
  inspect = require("util").inspect;

var imap = new Imap({
  user: "[e-mail]",
  password: "mypassword",
  host: "imap-mail.outlook.com",
  port: 993,
  tls: true
});

function openInbox(cb) {
  imap.openBox("INBOX", true, cb);
}

imap.once("ready", function() {
  openInbox(function(err, box) {
    if (err) throw err;
    var f = imap.seq.fetch(`*`, {
      bodies: "HEADER.FIELDS (FROM TO SUBJECT DATE)",
      struct: true
    });
    f.on("message", function(msg, seqno) {
      console.log("Message #%d", seqno);
      var prefix = "(#" + seqno + ") ";
      msg.on("body", function(stream, info) {
        var buffer = "";
        stream.on("data", function(chunk) {
          buffer += chunk.toString("utf8");
        });
        stream.once("end", function() {
          console.log(
            prefix + "Parsed header: %s",
            inspect(Imap.parseHeader(buffer))
          );
        });
      });
      msg.once("attributes", function(attrs) {
        console.log(prefix + "Attributes: %s", inspect(attrs, false, 8));
      });
      msg.once("end", function() {
        console.log(prefix + "Finished");
      });
    });
    f.once("error", function(err) {
      console.log("Fetch error: " + err);
    });
    f.once("end", function() {
      console.log("Done fetching all messages!");
      imap.end();
    });
  });
});

imap.once("error", function(err) {
  console.log(err);
});

imap.once("end", function() {
  console.log("Connection ended");
});

imap.connect();

But, I’m getting the following error :

Fetch error: Error: The specified message set is invalid.
Done fetching all messages!
Connection ended

@mscdex please help !!

@mscdex Done, the problem was with the source range, I used imap.seq.fetch("*", options) and worked with gmail but it didn’t work with hotmail/outlook so i changed it to “1:*” Relates #615

Ah ok, yeah not all server IMAP implementations behave correctly, especially outlook/exchange from what I’ve seen in the past.
