Please review the current system requirements for setup considerations and suggestions for your processor and RAM. Review each section in advance before making expensive hardware and network decisions that may not be in line with CloudNine recommendations.
When setting up permissions, make sure all users have full network access to each database directory they need to work with. |
Please keep informed of Concordance Desktop release updates and how they impact your system, by checking our Concordance Desktop Release Notes.
The minimum system requirements for Concordance Desktop Server are:

• Microsoft Outlook 2013 or higher (32 bit) •.NET Framework 3.5 AND 4.7 or higher •Internet Protocol v4 (IPv4) *IPv6 is not supported |
In addition to the above, the server also requires two open ports in the firewall for inbound and outbound traffic. By default, reviewers use Port 443 because it’s generally already open on most firewalls and is typically used for SSL packets, so beware of packet monitoring protocols. The default Admin Console Port is 10001 for administrators, since it’s typically not used by other services.
Performance is directly affected by clock speed and can be improved by selecting an SSD for your server. |
User capacity of the Concordance Desktop Server is metered by the hardware. Based on the number of users that need to be supported, you can combine multiple CPU servers to have the proper user capacity available.
•A Pentium CPU supports 25 users.
•A Xeon or Pentium Hyper Threaded (HT) CPU supports 50 users.
•Multiply CPU capacity for dual and quad CPU servers.
•Server capacity is also limited by bandwidth on your LAN and Internet connections and by file server speed.
•The Concordance Desktop Server requires a minimum of 1 GB of available hard disk space for installation of software, generated logs and temporary files, plus additional space for databases.
•We recommend storing databases directly on the Concordance Desktop Server for highest performance and system reliability.
•Indexing, reindexing, and packing may require extra disk space.
•Performance may be affected by indexing, overloading of available Internet or LAN bandwidth, or in situations where databases are not stored directly on the Concordance Desktop Server.
•If performance is an issue, add processors with a higher clock speed, an SSD, or additional bandwidth.

You cannot access Concordance Desktop databases on a machine that has IPV6 enabled. If you plan to run Concordance Desktop mobile, you need to ensure that your machine does not have IPV6 enabled. If it does, you need to disable IPV6 and use IPV4. Note that by default, Windows 10 (and later) automatically enables IPV6. For more information regarding the disabling of IPV6, please see the Microsoft article on IPV6 configuration guidance.
