On my pc (Part of Network) when I try send an email to some people via outlook, I always get the "mail undeliverable" when I select the address from the address book in outlook. However when I type the address in manually it's fine an the email is sent.
I have already tried downloading a copy of the global address book and I am still having the same issue, it must be something on my pc as no one else in the network is having the same difficulties.
