Ive been wrestling with IMAP & office365 all day with no success.

Near as I can tell the login fails, despite making the imap connection first then requesting the connection be upgraded to TLS using **$imap->starttls** .

I am running on strawberry perl 5.20 on windows 7 64bit.

**CODE:**

```
#!/usr/bin/perl
use strict;
use warnings;

$|=1;
$ENV{'PERL_LWP_SSL_VERIFY_HOSTNAME'} = 0;

use Data::Dumper;
use Mail::IMAPClient;

my $host = 'outlook.office365.com';
my $id = 'XXX';
my $pass = 'XXX';

print "Anon connect to IMAP\n";
my $imap = Mail::IMAPClient->new
(
    Server   => $host,
#   Username => $id,
#   Password => $pass,
    Debug   => 1,
)
|| die "Failed to connect to IMAP server\n";

print "Upgrade connection to TLS\n";
$imap->starttls
(
    SSL_verify_mode => 0,
) or die "starttls failed: $@\n";

print "Logging In\n";
$imap->login($id, $pass);

print "Getting Folder\n";
my $folder = $imap->Folder();
print "Folder = $folder\n";

print "Listing Folders\n";
foreach my $f ( grep($imap->selectable($_),$imap->folders ) )
{
 print   "The $f folder has ",
                        $imap->unseen_count($f)||0,
                        " unseen messages.\n";

}

exit;
print "Listing Folders\n";
foreach my $f ($imap->folders)
{
    print "The $f folder has ",
    $imap->unseen_count($f)||0, " unseen messages.\n";
}

```

**OUTPUT:**

```
