Exchange Server


Microsoft Exchange is considered by many to be the industry standard for email systems and has been for a long time.

Exmos has been working with Exchange since the beta versions prior to its launch in 1996.


Microsoft Exchange can fit the needs of a single server (Small Business Server) organisation through to the largest enterprises with tens of thousands of employees. Not only does this mean even the smallest organisation can have access to such a full featured e-mail system but, importantly, it can scale to meet the organisation's needs as it grows.


Microsoft Outlook is the default e-mail application for Exchange, offering not only e-mail, but contacts, calendaring, notes etc.

Outlook Web Access (OWA)

For web access, Exchange comes supplied out of the box with a fully featured web based e-mail gateway. This is then properly secured using the HTTPS (Secure Sockets Layer - same as for e-Commerce purchases) protocol and an appropriate SSL certificate. Webmail is then typically accessed through an address such as

Configuring the HTTPS and certificates for Outlook Web Access on Exchange 2003 for a single server is however, not a straight forward process. It is very easy to mis-configure the webmail element and open up access to many other elements of the server to the Internet. This access point is also used by mobile users synchronising with Windows smart phones, so the configuration is very critical.

Exmos spent a considerable amount of time perfecting this configuration and it is now running at a number of different locations providing both webmail and smart phone access.

Windows Smart Phones

Exchange Server also comes supplied in the box with the necessary components (Server ActiveSync) to enable synchronisation of e-mail with Windows Smart Phone and Windows Mobile based devices. This can prove considerably more cost effective than using other devices such as Blackberry which require the purchase of a separate server system (and hardware) to make it usable.

Lately a number of non-Microsoft Smart Phone manufacturers have been supplying Server ActiveSync support and we now have a number of customers accessing their e-mail using Nokia, Apple iPhone and Google Android devices.

Exchange Archiving

One of the main problems with Microsoft Exchange is the abundance of Personal Storage (PST) Files for archiving which can gather on every laptop server and hard disk possible. Managing and trying to back up these files can be close to impossible.

Exmos have an Exchange Archiving solution available and at a non-enterprise cost that is in line with the typical spend in the SME/SMB sectors.

Archiving in Exchange also provides additional benefits over and above the obvious PST fix. These include reducing the size of the Exchange database (store) for easier management as well as regulatory/discovery purposes.


Exmos' SentiLAN network monitoring system is used to keep tabs on the Exchange Server.
