Welcome to MailSite Fusion 10. These release notes contain valuable information on the latest features and improvements in this release of MailSite Fusion.

MailSite Fusion 10 includes an enhanced ActiveSync server that brings native email, calendar and contact sync to Microsoft Outlook 2013. It also brings support to an increased list smart phones for push email, calendar and contact updates over-the-air to BlackBerry, Windows Mobile, iPhone, Android, iPad and other smart phones and tablets. For all but the BlackBerry devices, this is achieved without any plugins, and no expensive and complex middleware is required.

We have invested significant amounts of time testing and profiling MailSite services against many different use cases and clients. This has allowed us to implement caching strategies to improve the responsiveness of the services while significantly reducing disk and network IO.

We have enhanced the ExpressPro web client to make use of the performance improvements, and added support for responding to meeting requests and offline mail processing.

The main new MailSite Server version 10 features are:

• A updated look and feel for the ExpressPro web client with full pane message viewer and reorganised controls.
• Server and domain administrators can now manage and configure user�s accounts, and domain settings from within ExpressPro.
• Password complexity and account lockout options for ExpressPro and Airsync.
• Improved support for large folders in Webmail with partial loading and dynamic scrolling.
• Improved loading structure to decrease inbox render times.
• Atomic operation support for common IMAP and Airsync operations to improve client response times.
• Outlook 2013 ActiveSync support providing true native calendar, contact and email synchronization to your desktop, mobile device and the ExpressPro web client.
• IMAP Idle delivering PUSH email to your inbox.
• Support for responding to meeting requests.
• Distributed SQLite mail store index caches for increased IMAP, POP and Delivery performance.
• Significantly reduced disk and network I/O.
• Faster Anti virus update processing with progress visible though the MailSite console

• Upgrade installation
• New installation

This covers an upgrade from any installed version of MailSite (4.x, 5.x, 6.x, 7.x, 8.x, 9.x). The upgrade installation process keeps all the previous settings and does not make any modifications. It will, however, add a new Windows account called MSIISUSER and will add some non-intrusive permissions to this account for the use of MailSite ExpressPro running under the IIS web service. This new Windows account is a standard user we have adopted which will be needed in future MailSite upgrade installations. The only problem that may occur is that propagation of this new user rights can take a long time if the message store is large.

The upgrade installation process does take into consideration previous MailSite Clustered installations. All permissions, settings and configuration settings will be left intact.

IMPORTANT: With the release of MailSite 9.4 The Express and Pocket web clients are no longer supported. If they are installed on your system they will be removed during the upgrade process. Please contact support if this presents a problem for you or your customers.

The new installation assumes that any previous version of MailSite has been removed or the operating system has been newly installed. The installation will configure MailSite with the necessary accounts and permissions for the MailSite directory and subdirectories.

• SQL server is required
• At least 2 servers are needed for a clustered environment
• A Specific MailSite user needs to be pre-configured with access to the:
• BOX directory location
• The MailSite directory location
• Access to IIS for use with MailSite Web Servcies

The installer will set sufficient user and folder permissions for MailSite and all of its components to run in a single server configuration. The following default permissions are assigned by the installer:

Within this release of MailSite there are these known issues within the product that will be resolved in a future release :-

In some circumstances, where local text is longer than the equivalent English text, controls on some ExpressPro pages are misaligned.

Some error and warning messages are shown in native English when a local language has been configured.

ExpressPro supports a wider range of Recurrence rules than are currently supported by Outlook.  In some cases Outlook may fail to display complex recurring events or display an error when amending such events.  Clearly we have no control over Outlook's recurrence feature set, so would encourage simple recurrence rule usage when planning to synchronizing with Outlook.

After synchronizing Contacts between Outlook and ExpressPro, formatting of the Outlook notes field may be changed.
