i am running ZCB 5.0.18 with Outlook 2007 without service pack, BES 4.1.7 and Zimbra 6.0.2.

I have mail filtering rules on zimbra, and rules works as espected on the web UI. However, i receive in the blackberry each filtred email twice : once copy into the right folder according to the rule, and another copy into the blackberry INBOX ... This is pretty annoying, is it a way to change that ?

ps: not regarding this particular issue : should i switch to Outlook 2007 SP2 ?
