Configure IIS for Microsoft Exchange ActiveSync

This article applies to recent versions of SmarterMail Enterprise. View articles for SmarterMail 15.x and earlier.
Microsoft Exchange ActiveSync is available as an optional add-on to SmarterMail and is associated to a specific SmarterMail license key at the time of purchase. Before ActiveSync mailboxes can be assigned to user accounts, you will need to adjust your IIS configuration settings.
 
Make sure your mail domain has a valid SSL certificate an SSL connection is required when using EAS. For more information, see Configure SSL/TLS to Secure SmarterMail.

We are using IIS7. Only find the Anonymous Authentication. No Windows Authentication!

I purchased this add-on and went to follow these instructions only to find I too don't have "Windows Authentication" listed! How do I get this to work? I'm also using IIS 7.

Are there instructions for Configuring IIS 8.0 for Exchange ActiveSync?

The same process applies to IIS 7 and 8+. We've updated the article to reflect this.
