Hello Michael, first things first thanks a lot for your quick response. 
I understand that Outlook needs some time to synchronize, but my 
impression is that the system became slower with every new mail account 
I synchronize. What makes it difficult for me to analyze the situation 
is that I have problems setting up Activesync for logging per device (or 
single file at the moment). This weekend I upgraded everything to the 
newest version of Horde 5.2.10 . Maybe logging is a little buggy (or 
me!). The entries in the gui result in these entries in the conf.php:

$conf['activesync']['logging']['path'] = '/var/log/activesync';
$conf['activesync']['logging']['level'] = '2';
$conf['activesync']['logging']['type'] = 'perdevice';

The folder has been given the right permissions but even after a reboot 
no files ever show up in it. If I give folder path 
'/var/log/activesync/' I kill horde more or less completely.

Can you confim this behaviour, or is it me going wrong somewhere? Best 
regards, Jens.
