This may be something that is too hard, but we'll see:
We have an Exchange 2003 server that we have two ways of connecting to:
1) We have people inside the company on the LAN that connect to the Exchange server via Outlook. We have no problems there
2) We have people on the outside that connect to the network via VPN first & then Exchange via Outlook.
We are having problems with the second group of people connecting to Outlook. Their Outlook says connected, but it doesn't download any new messages. They can send messages, but not receive. They are able to send/receive via OWA. The strange thing is that they can do everything else on the network over the VPN, so we do not think it is a VPN issue.
Has anyone ever heard of a similar issue? If so, what is the fix?
