We have added a new test called “Office365 Vanity/Custom Domain Name Settings Test for Lync" to the Lync Remote Connectivity Analyzer site.

The Lync Server 2010 Remote Connectivity Analyzer is a great tool for testing, troubleshooting, and performing diagnostics on Communications Server 2007, Communications Server 2007 R2, Lync Server 2010, and Office 365 deployments.

Have you ever wanted to verify that your remote access was set up and configured correctly? What do you do when you get a call or an escalation regarding a service or connection that is not working? How do you verify whether the issue is with an individual user or is affecting the whole organization? And if there is a problem, where do you start troubleshooting? Is it a DNS problem? Is it a certificate problem? Is a port not open on the firewall?

The Lync Server 2010 Remote Connectivity Analyzer is a great tool to perform testing, troubleshooting, and diagnostics on Communications Server 2007, Communications Server 2007 R2, Lync Server 2010 and Office 365 deployments. The tool will help you get answers to the questions listed earlier in this article, and should be your initial stop when attempting to troubleshoot a connectivity issue.

The Lync Server 2010 Remote Connectivity Analyzer is a web site that administrators can use to validate and diagnose end-to-end communication scenarios. The site simulates multiple client access scenarios from outside the customer's infrastructure and reports whether the test was successful. Figure 1 shows the site landing page.
