Just wanted to give people who didn't read the front page http://www.quartzdevelopment.com that we have just released PortaMail Live, this product is a wireless sync which doesn't require any software installing on your servers to sync your Windows Mobile device to GroupWise, all you need to do is enable the soap port on your GroupWise server.
We have also created a new forum for PortaMail Live for people to ask questions in.
Thanks,
arb.
