Duplicated contacts in Outlook - WM6.5

[dvet]

Please, did anybody else encounter this?:
I sync with Exchange via GPRS (it is Kerio MailServer). Everything works fine except contacts - most of them appear twice on my mobile...on desktop Outlook they appear only once as they should...I used to synchronize my previous HTCs (Kaiser, TyTn, TouchPro) without this problem - it appeared just now, once I moved to TouchPro2 (Rhodium) ... the problem appeared also on WM 6.1. I tried to delete my mobile device from server, deleted and recreated an account on TP2 ... no success and I am out of ideas - any hint, please?

I have got almost the same problem. When I sync my phone with Outlook 2007 everything goes well. When I flash a new ROM on my phone and sync again, all my contacts and appointments are duplicated, as well in Outlook as in my phone. I use Duplicates Remover from MapiLab to remove the duplicates. After that Outlook and my phone sync and everything is okay.
