Glad to hear Graham, Macs are great machines, despite Bob's efforts or problems. I've been working on Macs for 20+ years, as well as Windows machines, and all in all more people would rather use Macs (that I've come across) though more are required to use Windows because of company standards, and systems that are not set up to work with Macs.

Some of the problems you are facing with Outlook/Entourage are problems caused by Microsoft themselves (Data file format differences) though you can find products out there to help with this conversion.
