I have moved exchange 2003 server to a new Box, able to send and receive the mails, In client systems outlook is configured using RPC/HTTP, laptop users should be able to access mails from outside also, we dont use any VPN.
Internally if i configure outlook as MAPI, its working fine, but if i configure through RPC/HTTP, its very very slow and taking 5min to resolve the username itself.i have added exchange server ip adress in system host file, after that its connecting faster,
But when i m trying to connect externally , not able to connect to the server, only can access mails through OWA, when away from office
is it problem with DNS(resolving externally) or any other problem,
