Can someone please point me to some information regarding the setup required to have external clients access their outlook email remotely.
Currently all users can access their email through Outlook Web Access.
I have followed steps from Microsoft Exchange Server's Admin Pocket Consultant and successfully set up a remote mail client.
The client has successfully downloaded all of the mail to its local cached copy.
As soon as this client is plugged into a foreign network (to the domain) or uses a dial up internet account it cannot resolve the mailserver's name and therefore can not retrieve any new mail or send mail. (They cannot ping the mailserver's name either as they could whilst on the domain in the office - as a stand alone workstation - not part of the domain.)
Does a unique DNS entry need to be made in order for people to connect to the mailserver?
Is this a firewall situation that needs to be addressed to allow the remote clients exclusive access to a different protocol?
Please can some point me in the right direction?!!
