Hosted Microsoft Exchange Mailboxes



Service Announcement


We are delighted to announce that Hosted Microsoft Exchange Mailboxes have now been formally added to our Service Catalogue. If you would like to purchase the service or need support on it, please contact us in the normal way.

Service Name

Hosted Microsoft Exchange Mailboxes

Service Dates

This service was added to our service catalogue on 1st February 2008.

Service Description

Hosted Exchange Mailboxes deliver business class email hosting. Our packages include up to 250GB mailbox storage on Exchange 2016 – we’re told we supply the biggest mailbox quota in the UK! The mailboxes sync seamlessly with smartphones, can be connected with Outlook (or use the free Outlook Web App) and as you might expect the sharing features are robust. The service now also includes company wide signatures at no extra cost.

Service Mandate

This service was initially introduced to support business that increasingly wanted to take their email hosting off their site and into the cloud. This sounds strange now but back in the early 2000’s businesses still managed email on premises, which caused pain for remote workers. Now, we continue to offer the service due to the reliability of the platform, the continued use of Outlook by most business customers and to offer a solution which provides a Microsoft platform that is not hosted by Microsoft.

Service Notes for Customers


Basic Spam Protection Included

The basic level of antispam protection for these mailboxes is to detect spam email and do one of the following:

  • Delete Spam – Emails considered spam are deleted and not delivered to the email mailbox.
  • Warn In Subject – Emails considered spam are delivered to the email mailbox but have the word **SPAM** added to the subject line. (This is the default and recommended setting)
  • Ignore Spam – Emails considered spam are delivered to the email mailbox as normal and no action is taken.

This is not particularly sophisticated but it does show us that with the default setting emails will still be delivered. In this way you will not “lose” any genuine emails as a result of the filter but you can take extra care when opening them.

Additional Email Security & Archiving Option

Protect your users from unwanted spam and malicious messages with our cost-effective Email Security & Archiving Option. With no hardware costs and an easy setup method you’ll benefit from these more sophisticated features:

  • 1 Year or 10 Year Email Archiving Service
  • Spam Levels of Ultra Light, Light, Medium and Severe, which describes how strong the filtering is.
  • Whitelisting – We can add a domain or email address so emails from that sender are never treated as spam.
  • Blacklisting – We can add a domain or email address so emails from that sender are always treated as spam.
  • Reporting – An email report is available if you require a regular update of the activity within your account. This report will be emailed to your inbox at a time, period and frequency of your choice and contain all inbound and outbound email listing, including spam and viruses, allowing you to check the performance of Email Security on your account.
