I had issues with imap_status not working correctly, while other imap functions seemed okay. I always got the ['flags']=0 response. No notes here and Google searching suggests it doesn't working properly with Exchange, so I wrote a little workaround, to at least get some information.

<?php
    function my_imap_status($stream, $mailbox='', $info=SA_ALL)
    {
        // get current mailbox name (and info)
        $curr_obj=imap_check($stream);
        if(!$curr_obj) return false;
       
        // if request if for current mailbox then just return it
        if( (empty($mailbox)) || ($mailbox==$curr_obj->Mailbox) ) return $curr_obj;
       
        // get current mailbox
        $current_mailbox=$curr_obj->Mailbox;
       
        //switch to new mailbox
        if(!imap_reopen($stream, $mailbox)) return false;
       
        // get info
        $obj=imap_check($stream);
       
        // switch back to original mailbox
        imap_reopen($stream, $current_mailbox);
       
        //return info
        return $obj;
    }
?>

another tips is to get only total number of message and recent message

$imap_obj = imap_status($mbox, '{mail.mysrv.com:143/imap}INBOX', SA_MESSAGES+SA_RECENT);
echo('<pre>'); var_dump($imap_obj); echo('</pre>');

In 'reply' to my previous post;
I`m not sure of that anymore
I think this trick works,
but the rest of my script just sucks..

Conclusion:
You can get the last UID by using status->uidnext-1
BUT: This is not a good way, if another message is added after your append and before your status; you are screwed
