Features that are included in this update
The Hosted Email add-in framework provides extensibility in Windows Server 2012 Essentials that lets you integrate a remote third-party email service. The framework simplifies the development process of an add-in by providing the following capabilities:
- Defines a standard adapter interface in which you can provide the logic to connect the built-in provider by using your own hosting services
- Contains a set of built-in standard UI extensions for integrated management in the Dashboard (You can also create custom UI extensions.)
- Contains a built-in provider that implements the business logic on the server for integration scenarios (Additionally, the provider exposes an object model that your UI elements can call into in order to access administrative functions.)
Feature 2AntiXSSLibrary.dll is updated to the latest version. This improves the reliability of the Remote Web Access (RWA) page.
Feature 3The Microsoft .NET Framework 4.5 package is updated to a new version. This package updates the .netfx client package to the latest version in order to improve the reliability of the client connector and other dependent features.
Feature 4A direct download link is added to the Dashboard to improve the online backup integration experience.
Major issues that are resolved by this update
Issue 1You cannot view Office 365 information through the Dashboard. This issue occurs if the proxy settings are configured to automatically detect the proxy server in Windows Internet Explorer.
Issue 2The file history retention policy does not work together with certain time formats.
Issue 3A hard block occurs on the hardware checks for a hoster.
Issue 4The system returns user tokens instead of cookies in Web API. This may cause a cross-site request forgery (CSRF) issue.
Issue 5The Dashboard crashes when a user add-in is configured as a leftmost add-in.
Issue 6The Domain Configuration Wizard fails if the domain name contains "homeserver" (for example, the domain name is "smithhomeserver.com").
Issue 7The certification authority (CA) root certificate is incompatible with DirectAccess. Therefore, after you deploy DirectAccess on a server, a Windows 7-based client cannot establish a DirectAccess connection to the server.
Note This fix takes effect only if Update Rollup 1 for Windows Server 2012 Essentials is applied before DirectAccess is deployed on the server.
