This page aims to give a detailed overview of customer-projects accompanied by the Open-Xchange professional services team: The different phases and decisions as well as the documents necessary to accompany this process are listed here. The following diagram gives a birds-eye view of the whole process:



During this phase the product gets demoed and the doability of the project is checked. After this phase a detailed offer is made and the customer decides whether to start the project or not ("Go / No-Go").

  • Technical Demo (webcast or on-site)
    • presentation of the product including all features relevant to the customer
    • determine customer´s goals (replace webmail? operating parallel to MS Exchange?)
    • OX USPs: Fast even with many mails, drag-n-drop in the browser, syncing with many different clients, social, upsell
    • demo-systems could be,, own VM -> 2 users and some data are needed
    • recommend
  • Architecure Overview
    • Integration with customer systems instead of out-of-the-box (provisioning, mailsystem [none is included!], CPanel, PBA/POA, Plesk)
    • There are many ways to OX and its data. Broad range of supported devices and browsers
    • Java, no proprietary formats or protocols, Apache, MySQL
    • scales horizontally as well as vertically. Cluster size is entirely choseable, multiple tenants on one system -> "server density"
    • show examples for 10K users, 100K users, 1M users
    • APIs (HTTP, SOAP, RMI, ex- and import)
    • whitelabeling for GUI, Outlook, OutlookInstaller, MobileGUI (branding, theming, detailed configuration with ConfigCascade)
  • Proof Of Concept (POC)
    • needs server (real or VM) with SSH-access, a few accounts on the existing mailsystem
    • inform customer as soon as it is ready, get feedback after 2 weeks, are there still open issues open in R&D, Sales or Marketing?
  • Technology Transfer
    • approximately 10 mails.
    • evaluate customer-environment (what kind of mailsystem, loadbalancer, storage, number of mailboxes?)
    • hardware-sizing (how many concurrent sessions)
    • provisioning (existing or custom?)

During this phase it is decided what exactly there is to do, by whom and when. The resulting Customer Implementation Concept formalizes this information, accompanied by (several) SOWs which detail Open-Xchange efforts.
