Description:
------------
Connecting via imap_open() to outlook.office365.com (and other hosts) takes over 7 seconds from Windows OS only.  The same script below works quickly on Linux & OpenBSD.

Test script:
---------------
$start = time();
imap_open(
 '{outlook.office365.com:143}',
 'xxx@yyy.com',
 'password',
 null,
 1,
 ['DISABLE_AUTHENTICATOR' => ['GSSAPI','NTLM']] // used with and without this param
);
print_r(imap_errors()); // none returned
print_r(imap_alerts()); // none retured
die("Time " . (time() - $start) . " seconds\n");

Expected result:
----------------
Time 0 seconds
or 1 second at most.

Actual result:
--------------
Time 8 seconds.
I used NtTrace to find the slowness.  There are lots of errors/warnings, but I'm not sure what is relevant.  Below is an excerpt of where things slow down.  Full debug log is attached at patch.
