Can you ping the server?<br />
Can you connect to the server with a MAPI client?<br />
Have you verified all relevant Exchange services are started?<br />
Have you changed any firewall rules lately?<br />
<br />
For troubleshooting OWA - make sure basic and integrated authentication are set on all Exchange virtual directories in IIS, also make sure anonymous is enabled on /exchweb.<br />
<br />
Are there any errors in the application or system event logs?<br />
Can you telnet to port 25 on the server and test the mail relay using Telnet?<br />
Is email being delivered internally between mailbox users?<br />
