Before beginning the installation of MailStore Service Provider Edition it needs to be ensured that all system requirements are met.

Hardware

Single Server Mode or Individual Instance Hosts

The calculator below helps to specify the hardware needs in a single server mode setup or for an individual instance host in a multi-server mode setup subject to the number of users, instances, stored email, and the archiving strategy.

System Requirements Calculator

Calculations are based on the following base values:

  • Email Volume (User/Year): 10000
  • Email Size: 75Kb
  • Compression Ratio: 60%

Software Requirements

The below system requirements only apply to MailStore Service Provider Edition and its components. Client applications such as the E-mail Archive Client and E-mail Archive Add-in for Outlook have their own system requirements. As both applications are identical to MailStore Client and MailStore Outlook Add-in, their system requirements can be found in the MailStore Server help.

  • Following operating systems are supported
    • Windows Server 2008 R2 SP1 Standard, Enterprise or Datacenter (Server Core Installation)
    • Windows Server 2008 R2 SP1 Standard, Enterprise or Datacenter (Server with a GUI)
    • Windows Server 2012 Standard or Datacenter (Server Core Installation)
    • Windows Server 2012 Standard or Datacenter (Server with a GUI)
    • Windows Server 2012 R2 Standard or Datacenter (Server Core Installation)
    • Windows Server 2012 R2 Standard or Datacenter (Server with a GUI)
    • Windows Server 2016 Standard or Datacenter (Server Core Installation)
    • Windows Server 2016 Standard or Datacenter (Server with a GUI)
    • Windows Server 2019 Standard or Datacenter (Server without Desktop Experience)
    • Windows Server 2019 Standard or Datacenter (Server with Desktop Experience)
  • Following web browsers are supported by the Management Console:
    • Microsoft Edge
    • Microsoft Internet Explorer 10 or higher
    • Google Chrome 18 or higher
    • Mozilla Firefox 18 or higher
    • Apple Safari 6 or higher
  • .NET Framework 4.5.1
    The appropriate Windows Server feature will be enabled automatically by the MailStore Service Provider Edition installer. In environments with centrally managed Windows updates the automatic installation may not succeed. In such cases the installation of the .NET Framework 4.5.1 feature must be done manually before executing the MailStore Service Provider Edition setup file.

    Important Notice: On Windows Server 2008 R2 Core, the features NetFx2-ServerCore and NetFx2-ServerCore-WOW64 must be installed prior to executing the setup. Otherwise the .NET Framework 4.5.1 installer fails silently.

  • IFilter drivers (optional)
    For indexing email attachments other than TXT and HTML files, additional IFilter drivers are required. Please refer to Search Index for further details about attachment indexing.
  • It is not recommended to install MailStore Service Provider Edition on servers that already provide other network services. Especially with email or web servers TCP port conflicts are likely to occur. Specifically, Microsoft's Internet Information Server (IIS) MUST NOT be installed on any server that hosts the Client Access Server role.

Network Requirements

  • Verify that the DNS name of the MailStore Service Provider Edition servers match their actual computer name and that all servers have a proper forward and reverse DNS resolution configured.
  • Do not intercept connections from or to MailStore Service Provider Edition servers with web or email proxies. Read Notes on Antivirus Software in the MailStore Server help for further details.
  • To guarantee a decent user experience, the available bandwidth of the network connectivity should be at least 100 MBit/s (symmetric).
  • The Management Server Role must be able to access my.mailstore.com permanently on port 443.
  • For communication between MailStore Service Provider Edition services, access to the MailStore Management Console and end user access to instances, the following TCP ports are opened by the MailStore Service Provider Edition services and must therefore not be used by any other service.
Port Role Description
143 Client Access Server The standard IMAP port is used to provide read-only access to archived emails via IMAP protocol. The IMAP server on this port supports unencrypted as well as TLS secured connections (recommended) that have been initiated by the email client via STARTTLS command.
443 Client Access Server The standard HTTTPS port is used to provide SSL encrypted access to MailStore Instances via MailStore Client, MailStore Outlook Add-in, MailStore Web Access and MailStore Mobile Web Access.
993 Client Access Server The standard IMAPS port is used to provide read-only access to archived emails via IMAP protocol. The IMAP server on this port support SSL/TLS encrypted connections only.
8470 Management Server This port is used to provide administrators access to the Management Console via web browser. The HTTP server on this port support SSL/TLS encrypted connections only, also known as HTTPS.
8471 Management Server Instance Hosts and Client Access Servers connect to the Management Server through this port.
8472 Instance Host Client Access Servers and the Management Server connect to the Instance Hosts through this port.
8473 Client Access Server Management Server connects to Client Access Servers through this port.
