The URL could even be http if SSL is not configured on the server to be required.
Testing active sync using a browser returns as an error in the browser window of Error 501/505 - Not implemented or not supported.
For Exchange 2007 and Outlook Web Access 2007, the error 501 and 505 seen on the page displayed is actually normal and should be the response the browser receives from the web server. After all, it's not a mobile phone it's a browser.
Although the error massage has changes slightly in windows server 2008 and windows server 2008 R2, it is very similar. The URL for testing activesync and remote support for active sync of course is still in new versions of Exchange. Microsoft Exchange 2007 and Microsoft Exchange 2010 still use the same service point with the IIS web server structure and virtual directories.
To the remote user and to the smartphone it's still the same. underneath, server side, there have been many changes to Internet Information Services. In Windows server 2008 and 2008 R2, IIS has undergone many functional and interface changes for server administrators. When trying to setup a smartphone or mobile device, iPad or iPhone for activesync to get email from an exchange server, the URL is still the same. Web based remote support software can assist in access the server remotely and working out the issues with the configuration and also help solve connectivity issues remotely as well. The URL that can be used to test active sync access and connectivity is the same and can be tested bot internally and externally . The difference being of course what name is entered into the browser and support for internal and external access is the same as well.
