I have an Exchange 2003 with OWA running. &nbsp;Users can access it easily from most places. &nbsp;There is one location, from which our users cannot access OWA. &nbsp;They have internet access and can open webpages in general but not my OWA. <br />
<br />
I suspect they are blocking some ports in their network firewall configuration, and I would like &nbsp;to ask their IT guys, &nbsp;but I don't know which ports are required for OWA or what port(s) they might be blocking.<br />
<br />
TIA &nbsp;Naomi<br />

Blocked ports? - OWA Exchange 2003 not working from one location
