hi support, i have a slight issue with exchange configuration. a little bit about the server... exchange was installed on a windows 2008 server with the name suria.ksmb.local MX record is mail.suriamalaysia.com.my i have setup the exchange accordingly but i had an issue with receiving emails from external source. i could send emails to internal users and also external users. i could get reply from the internal users as well. however i couldnt get replies from external users. i have setup the firewall to accept all incoming and outgoing connections. now the issue is, i keep getting prompted with username and password when i open outlook. it worked before but doesnt work now. just to clarify..what user name and password am i supposed to logon with? my send connector and receive connector authentication is currently set to "none". i have tried the other options as well. none of which works. what should i do to get this functional? please help. thank you.

What version of exchange and how many exchange servers? If only one exchange server than you need to set your default receive connector to allow anonymous.

hey. thanks for your reply. its exchange 2010. and there is only one exchange server. outlook used to work but i dont remember what the settings were as i was a zombie at work at that time on my 20th hour working on exchange. i will keep trying the other settings and will post back if there are any results. i will follow the guide as per the link that you have attached. thanks.
