Create DNS Service Location (SRV) records for the Exchange Autodiscover service

In earlier blog posts I’ve discussed other DNS records such as the TXT SPF record.  This is a new but very important record that you will want in place for your domain.

Here’s a list of great resources that describe this in detail and include guidance to manually create and publish the record to whomever is hosting your DNS records for the domain.

  • Sean Daniels very good explanation with examples

    Both of those will fail in the default SBS case as the info is actually at https://remote.contoso.com/autodiscover. With Outlook 2007 SP1 and above, outlook adds a third check. It checks a SRV record, or service. When you run the Internet Address Management wizard with a partner, this SRV record is automatically set. It looks like:

    _autodiscover._tcp IN SRV 0 0 443 remote.contoso.com

  • This blog post goes into what the syntax means piece by piece …a tech deep dive meant to tie in their chat client software to Google Apps.  They do have a tester there too.  Realize that in the GoDaddy record wizard that for SBS you enter @ for the Name field which represents your domain name.
  • Susan Bradley post on the same including a Go Daddy creation guide
  • Microsoft KB 940881- A new feature is available that enables Outlook 2007 to use DNS Service Location (SRV) records to locate the Exchange Autodiscover service
  • Test your record here – https://www.testexchangeconnectivity.com/
  • double-check to ensure that it was correctly published by those hosting your domain’s DNS records – my fav http://www.intodns.com (but I don’t see SRV record reported) – tech sent me to http://network-tools.com but none of the tests there seemed to fit
