The AutoDiscover feature could be enhanced to answer also queries  
performed  by Microsoft Outlook Mail clients.

Mail clients like Outlook 2010 and older should auto discover there  
IMAP/SMTP settings, Outlook 2013 clients could be handled seperately  
to allow ActiveSync connections once EAS Protocoll 14.1 or above is  
implemented in Horde.

This Ticket relies an the implementation submitted in Horde Ticket  
11637 (http://bugs.horde.org/ticket/11637) to be able to analyze he  
request schema.

Please edit Horde/ActiveSync/Request/Autodiscover.php and enhance the  
function "_buildResponseString($properties)" to:


    protected function _buildResponseString($properties)
     {
         if (stripos($properties['request_schema'],  
'autodiscover/mobilesync') !== false) {

     else    return(_buildFailureResponse($properties['email'],

}

Please  be aware that this example has hardcoded values in the outlook  
response. It should be configurable in the Administration/ActiveSync  
prefs.
The following aspects should be configurable:
* Which protocol types should be configured for autodetection (IMAP,  
POP3, SMTP
* The server for each protocol type
* The Port for each protocol type
* If SSL is active for each protocol type
* If SMTP requires Pop-auth

This example with hardcode values is tested and works with MS Outlook 2010.
The ActiveSync profile for MS Outlook 2013 cannot be testet because  
Horde needs to implement EAS protocol 14 to allow MS Outlook  2013 to  
be used as ActiveSync client.

Many Thanks,
