I've got a client who would like to connect to his Exchange 2003 Mailbox from home using his laptop which is running Windows 7/Outlook 2010.
The office network is quite old and and the configuration is very limited as to what can be change to get this solution working. Exchange 2003 is running on Windows Server 2003, the firewall is only a simple BT Business Router so there is no VPN Dialler capability on the router. One interesting point is on the remote site, there is a Exchange 2003 Server which maybe could be used fo relay messages to the office exchange box and then out to the internet maybe?
Not sure which way we is going to be best.
