I'm using a 'un-modded/touched' iPhone 3G and have a strange issue with ActiveSync to my MSX2003 box.

It will 99% of the time, get new mail as and when it arrives.

but if I manually delete mail using Outlook on my PC, ActiveSync doesn't appear to relfect the changes on the phone, until a new mail arrives.

is this by design ? or a flaw ?

thx in advance
