Microsoft Exchange Server is the premier email platform built to deliver the enterprise-class security and reliability that businesses require. Microsoft Exchange provides email, calendar and contacts on your PC, Mac, smartphone and web browser.

The benefits of Microsoft Exchange include:

  • Up-to-date: Exchange server stores everything centrally, so you always see the latest version of your email, files, calendar and contacts.
  • Mobile access: Microsoft Exchange is the software that powers email for smartphones including iPhones, and Android or Windows-powered devices. It also offers access to email from virtually any browser, so you will always be synced with your team.
  • Shared calendars: Microsoft Exchange lets employees see colleagues’ availability to schedule or rearrange meetings, book conference rooms, and plan projects.
  • Shared task lists: Microsoft Exchange allows ‘to do’ lists to be created and assigned, then shared with team members. Managers can check off items as they are completed.

Microsoft Exchange server is the most effective solution for enabling employees to share information and work together productively.

Technical Overview

OneNet’s Hosted Exchange is built from the ground up to support security and reliability with unmatched scalability. A web-based control panel is included to enable you or your System Administrator to easily add and remove users and complete almost any Exchange-related customisations.


OneNet’s Hosted Exchange is built on the industry-leading Microsoft Exchange platform. OneNet takes advantage of many of the enterprise-availability features that are offered by Microsoft Exchange. For example, OneNet employs a “nothing shared” architecture and database availability groups (DAGs). This means that every component is, where possible, duplicated so that no single failure can impact the performance or availability of the service. The hosted email service is delivered from leading data centres in New Zealand and is an built on OneNet’s advanced Network Critical Physical Infrastructure layer.


OneNet’s Hosted Exchange utilises industry-leading mail filtering and security delivered by Trustwave’s MailMarshal and McAfee Antivirus. Over 90% of spam email is filtered before it even reaches our email environment through OneNet’s subscription to multiple IP reputation and blacklist services. The remaining email is filtered through OneNet’s self-learning anti-spam gateway servers.

The hosted email service is delivered from OneNet’s robust network and security core which is built on the same “nothing shared” architecture where all components are N+1 configured. That is, if “N” components are required, then there is always an extra “1” available in either an Active/Active or Active/Passive configuration. This means that there is always at least one component of the system available to automatically replace the service of a faulty one.

Enterprise-class Cisco Firewalls and Intrusion Prevention systems continually monitor the environment and mitigate security threats.

OneNet’s infrastructure is located in New Zealand Tier 3 data centres, and is protected 24 hours a day, 7 days a week, by on-site security personnel. The premises are controlled by sophisticated on-site security systems consisting of closed-circuit surveillance cameras and electronic tracking systems to ensure the highest level of physical security for OneNet’s Hosted Exchange network.

Control Panel

OneNet’s web-based Control Panel allows your organisation to manage your own user creation and deletion processes without the need to contact OneNet. This means that your System Administrators are able to complete almost any Exchange email-related tasks including:

  • User creation and deletion
  • Password reset and account unlock
  • Creation of Distribution Lists, Public Folders and Aliases
  • Ability to set and adjust mailbox quotas at global and user level
