Our office is having issues retrieving emails remotely using OWA. Our office had MS Exchange Server 2007 installed several months ago and we were able to access our emails remotely with OWA without issue until recently. The IT company that sold and installed the server is saying that we require a fixed IP address from our ISP to prevent this from happening again. Is this correct or are there settings in MS exchange server to identify the public IP address?
Software/Hardware used: MS exchange server 2007, Outlook 2007, Outlook 2002
