I have an interesting problem at the moment. I have an user/mailboxes ie Administrator, setup in exchange 5.5 which i can access through outlook on a local network desktop no problems.
However if i try to access the same Administrator mailbox from the exchange server i get the message the information store could not be opened.
Also if i VPN into the network the same issue occurs. The thing i am not sure of here is the LAN is a 192.168.0.0 network and the VPN provides an IP of 192.168.2.3 with a gateway of the same IP. I am also able to ping the exchange server on the network from the the computer connected via VPN and in the outlook settings able to connect to it as well, just cant seem to get any further than that and this is obviously doing my head in. Any suggestions would be welcome.
