Using the latest cutting edge toolsets, their system development processes are constantly changing producing some interesting challenges.
"After a long and careful consultation process, Business UX were contracted to design and replace all our servers. They worked over the weekend to ensure that there was no impact on our business and have provided systems which are now very reliable and productive."

Zarafa, the Preferred In-House Hosted Email System

Business UX offer a better way to implement Outlook for at least half the cost of Microsoft Exchange. The Zarafa Email and Messaging System is the accepted standard in Europe. Zarafa offers full native mapi Outlook connectivity, a superior webmail experience including calendaring, shared folders and tasks, the best mobile phone connectivity just to name a few. The Zarafa Collaboration Suite is an open and compatible groupware platform that can be used as a drop-in Microsoft Exchange replacement for mail, calendaring, collaboration and tasks. It includes IMAP/POP3 and iCal/CalDAV capabilities, the ability to integrate with existing Linux mail servers and a web-based access by means of an AJAX-based web client.

For companies who cannot trust the cloud for their email, need to be in control of their security, require 99.9% uptime and fast access should consider Zarafa.

Compelling reasons for implementing Zarafa rather than MS Exchange for in-house hosted email are Cost and Reliability.

Compare Zarafa with WebAccess, IMAP gateway and mobile synchronisation for unlimited users with rock solid performance against the cost for MS Exchange from prices obtained from Umart (in Oct 2015):
1) Microsoft Exchange Server Standard 2010 English 1 License DVD 5 Client Internet Price:$1835.00
Plus the Operating System to run it on
2) Windows Svr Std 2012 R2 x64 English 1pk DSP OEI DVD 2CPU/2VM, P73-06165 Internet Price:$1099.00
Plus client licences for the Operating System
3) MICROSOFT OEM Windows Server CAL 2012 English 1pk DSP OEI 5 Clt User CAL Internet Price:$255.00
Plus extra utilities such as Server Antivirus, Exchange Backup and Recovery Tools

Given how critical email and collaboration are to business, reliability is a crucial aspect of the email system selection process. It is a well known fact that Linux is far more secure than MS Windows. Because the infrastructure behind Zarafa is Security Enhanced Linux Enterprise, reliability and security far exceeds that of Windows servers.
The well-known reasons that lead to the damage of Exchange Database are: Server Dirty Shut Down, Virus Attack, JET engine errors, Abrupt system shut down, Server downtime and Headers corruption.
Exchange may experience a failure that requires the system to attempt to get back to a consistent state. Because there are different types of database corruption with differing symptoms, different tools and techniques are required to diagnose and fix problems. For example, once the .edb file is damaged, you will be needing an Exchange Database Recovery tool to recover users' mailboxes.
All these factors contribute to the downtime and expensive Total Cost of Ownership (TCO) of Exchange Email.
