I installed a new computer in a network with win xp and office 2003. The old one was win 2K with office XP.
The email is on an exchange server.
On the old computer (all on the exhange) there were groups of contacts and inside some groups there are other groups. On the new computer when we send to one of the top groups we get a message that it was unable to send to the group and does not define a specific email. Other addresses are sent o.k.
Any idea what to do?
