Our network has several WAN links connected by a frame-relay. If, for some
reason the link is down, Outlook 98 clients cannot connect to an Exchange
server on their own local segment. Outlook 97 clients seem to be OK.
We did try modifying the HOSTS files on all the machines to include a
reference to the local Exchange servers, but that still doesn't work.
Today for, example, we had a power supply fail on a router in one of our
offices. Until a replacement router is shipped and brought back online,
they can't send/receive Internet mail, AND they cannot even connect to their
own Exchange server to generate mail among themselves.
This was not a problem prior to the Outlook 98 rollout.
