Android, iOS, Win Phone can’t sync with Exchange – Event ID 3031
Running an Exchange 2003 Front-end / Back-end configuration there are certain settings that you need to make sure are enabled to allow ActiveSync to connect to the servers via SSL.
The best KB article I located that walks through this is KB817379.
In the article it instructs the creation of a secondary virtual directory for Exchange server. It tells you to go to IIS and open ‘Web Sites\Default Web Site\Exchange’ and export the configuration. And then walks you through the steps to create a new Virtual Directory.
Before going through these steps as instructed, there is a simple option that should be verified.
- Open to the Properties of the original Exchange directory.
- Under Authentication and access control, click Edit.
- Make sure that only the following authentication methods are enabled, and then click OK:
- Integrated Windows authentication
- Basic authentication
I have found that on some systems, especially for organizations that may have a mixed directory environment (i.e. Novell eDirectory and Active Directory) and have been running Blackberries, that ‘Integrated Windows Authentication’ may not be checked.
I won’t go into my personal opinion about allowing Android devices on a corporate network, but go to a search engine and enter “Android Security” and see what comes up. Another good resource is Kaspersky Labs: http://usa.kaspersky.com/search/apachesolr_search/android
From a security best practice, I would avoid it unless you can lock down the device to allow only corporate approved software to be installed. It seems Android is the preferred platform for mobile device hacking.
