While it is possible for the Mail Express Server and Add-In to work on system configurations other than those listed below, programs and hardware not listed below were not tested and are not supported.
Globalscape Quality Assurance (QA) tested and approved Mail Express for use with the programs and hardware described below. The minimum system requirements below are organized by Mail Express Server, SQL Server 2008 R2 Express, and Outlook Add-In requirements. The installer must be run by a user with administrative privileges on the computer. The installer/uninstaller will check for this at the beginning of execution.
Please review each of the requirements and prerequisites below and ensure that they are met before installing Mail Express. Ensure all Microsoft updates have been installed and the computer has been rebooted. If all of the prerequisites are not met, the installation will abort. You can print this page of the help and check off the requirements as you verify that they are installed/available.

While it is possible for the Mail Express Server and Add-In to work on system configurations other than those listed below, programs and hardware not listed below were not tested and are not supported. |
The system requirements/prerequisites on the computer on which Mail Express Server is installed are listed in the table below. The following important notes should be considered before starting installation.
Mail Express v4.2 and later installs .NET 4.5.2, if it's not already installed, and enables the ICAP service.
The ICAP service has to be installed and running for any ICAP functionality (integration with antivirus and data loss prevention tools) to work.
For Outlook Add-In system requirements, refer to Outlook Add-In Requirements/Prerequisites, below.
For SQL Server 2008 R2 Express system requirements, refer to SQL Server 2008 R2 Express Installation Requirements/Prerequisites, below. (These are the requirements that the installer verifies; refer to the Microsoft link below for additional SQL Server system requirements.)
For SQL Server 2008 R2 system requirements, refer to http://www.microsoft.com/download/en/details.aspx?id=12548.
Mail Express "silently" installs the latest version of the Java Runtime Environment (JRE) and Apache Tomcat; you do not need to update or maintain these applications.
Mail Express is supported with the following Oracle database versions:
Oracle Database 11g Release 2: 11.2.0.1-11.2.0.3 (patch set as of September 2001)
Oracle Database 11g Release 1: 11.1.0.6-11.1.0.7 (patch set as of September 2008)
Separate installers are provided for 32-bit and 64-bit installations. Please use the proper installer for your operating system. Mail Express integration with EFT only works with the 32-bit version of Mail Express. If you use the 64-bit installer, the EFT integration options will not be available, because the COM calls required for integration will not work. The EFT installer provides the 32-bit Mail Express installer.
If you are using Mail Express with EFT, you should use the Mail Express version bundled in the EFT installer. Mail Express and EFT compatibility depend on the version of the COM API built in to EFT. For example, Mail Express version 4.0.4 is compatible with EFT version 7; but Mail Express version 4.0.4 is not compatible with version 6.5.x of EFT, because their API versions are different.
The Java applet (for transferring files in a web browser) must be the latest available version.
|
Requirement/Prerequisite |
||
|
Mail Express Server must be accessible from the Internet, either directly or via the DMZ Gateway, if applicable, so that recipients can browse the attachment links to pick up attachments (typically in the DMZ behind a firewall such as Microsoft ISA Server). Using Globalscape’s DMZ Gateway server, the Mail Express Server does not have to remain in the DMZ and can reside within the internal network. When deploying the Mail Express Server in a virtualized cluster environment, setting a static MAC address for the server is required. |
||
|
Ensure that port 8443 is available to the Mail Express IP address (and that no port conflicts exist on that IP address). This port can be assigned to a specific IP address placed on the system for Mail Express expressly. If the firewall is enabled on the computer on which Mail Express Server is installed, you must create an exception for TCP port 8443. |

||
|

||
|
Anti-virus: (optional) The Mail Express Server computer should have a current anti-virus application installed so that attachments managed by Mail Express Server are free from malicious software.
|
If you are installing SQL Server 2008 R2 Express (available in the Mail Express Server installer for evaluation purposes), ensure that the computer meets the requirements/prerequisites in the table below. When you choose to install SQL Server 2008 R2 Express with the Mail Express Server installer, the installer will verify that the proper prerequisites/requirements are available before installing. If the requirements are not met, the installation will abort.
Listed in the table below are the requirements that the installer verifies; refer to the Microsoft link below for additional SQL Server system requirements.
If you are connecting to an external SQL Server 2008 R2 database, refer to the SQL Server 2008 R2 requirements.

Microsoft Visual Studio 2010 Tools for Office Runtime
Installer Name: Microsoft Visual Studio 2010 Tools for Office Runtime (VSTOR 2010) Redistributable
Installer File:
For 32-bit editions of Microsoft Windows OS - vstor40_x86.exe
On 32-bit editions of Microsoft Windows OS, it is not strictly required to install this prerequisite prior to installing the Mail Express Outlook Add-In because Outlook 2010 and later will automatically install the Microsoft Visual Studio 2010 Tools for Office Runtime if it is not already installed. This occurs the first time that Outlook loads the Add-In and does not require the user to have administrative privileges on the computer. However, this will cause a slight delay the first time end-users start Outlook after the Add-In has been installed. Administrators wishing to provide a more streamlined end-user experience may want to go ahead and pre-install this prerequisite.
For 64-bit editions of Microsoft Windows OS - vstor40_x64.exe
On 64-bit editions of Microsoft Windows OS, this automatic installation does not function for Outlook 2010; therefore, the prerequisite must be manually installed.
