Exchange Server Remote Connectivity Analyzer
The developers over at Microsoft have created a handy web tool called the Exchange Remote Connectivity Analyzer. It’s easy to find. Just head over to: www.testexchangeconnectivity.com. It’s a simple web page that lets you test all manner of connection types to your Exchange system. A few of the tests it can do are:
Microsoft Exchange ActiveSync Test
This test will simulate the steps a mobile device uses to connect to an Exchange Server using Exchange ActiveSync.
Microsoft Exchange ActiveSync AutoDiscover Test
This test will walk through the steps a mobile device uses to connect to the AutoDiscover Service
Microsoft Office Outlook 2007 Autodiscover Connectivity Test
This test will walk through the steps Microsoft Office Outlook 2007 uses to connect to Autodiscover
Microsoft Office Outlook 2003 RPC/HTTP Connectivity Test
This test will walk through the steps Microsoft Office Outlook 2003 uses to connect via RPC/HTTP
Inbound SMTP Email Test
This test will walk through the steps an Internet e-mail server uses to send inbound SMTP email to your domain
They have a few others as well. They are generally pretty easy to run through. Some of them may ask for a domain username and password for testing. If so, make sure you use a test account and change the password immediately after finishing any tests. Both for liability and security.
When you get the results, you can drill down into each individual step and see exactly what the test is doing and what response the server generates for it. This is where the tool shines. What may normally be a long, cumbersome troubleshooting task could instead be solved in a fraction of the time.
