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.

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

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..

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

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

$imap_obj = imap_status($mbox, '{}INBOX', SA_MESSAGES+SA_RECENT);
echo('<pre>'); var_dump($imap_obj); echo('</pre>');
