Microsoft state catagorically that you cannot synch to a public folder (my
org. has 2 Phenom users that want to update to a public folder).
Unfortunately, I don't have the link, but if you type 'synchronise public
folders' into
support.microsoft.com, you'll get to the link. They also then
have a recommended third-party piece of software to do this. My firm won't
pay, so the 2 people involved just copy the public folder to their contacts,
synchronise 1 way only (PC > Phenom), and keep changes/new contacts as notes
until they can add them directly when they're back in the office. Not a
perfect situation, I know, but it's simpler than getting a public folder
with a custom forms talking to a PDA.
