exchange-2003

Our organization just moved our Website/Domain to a hosted VPS. We elected, for the time being, to keep our email (Exchange) running at our office.

On our new VPS, we simply add a DNS record to redirect our mail to our on-site exchange server. This worked out well, as mail is coming and going with no problems.

Recently, we ran across an issue when setting up outlook from outside of our office (Not on same network as exchange server). When configuring mail server address, it keeps prompting for credentials.

Anyone got any ideas on why this is happening? Is our VPS not allowing Outlook to find our exchange server? If so, how can we bypass it?
