Exchange Mail System

Details of the Service

The corporate mail systems within the University run Microsoft Exchange 2010.  These systems have been designed to offer high availability and disaster recovery improvements over the previous version 

Access is available by using the native Microsoft Office mail client, Outlook; through the web interface NEMO, or through an IMAP client.

As with all University mail systems, incoming mail from offsite is scanned for viruses, and mail that is determined likely to be 'spam' is marked as such before being delivered to the mailbox.

The Exchange service provides email, a calendar/diary, a personal contacts folder, and facilitates group work and collaboration through Public Folders where files for such work can be stored.

To efficiently manage resources, Information Services has placed limits on the amount of mail each person can store in Exchange. As the limit is approached, a warning message will be delivered to the mailbox. If the limit is exceeded for a mailbox, mail will continue to be received, but no more email can be sent. Finally, when the amount of mail reaches an upper threshold, no mail can be sent or received.

The current mailbox limit within Exchange 2010 is 4GB.

A DS username and password with associated email address is required to access Exchange. If you are not sure what these are, please contact the IT Helpdesk for advice.

Accessing the Service


Outlook Client (Outlook 2010/2013 is recommended for an improved user experience)

Those with a network connected PC and with Microsoft Office installed can connect to Exchange using the native Exchange client, Microsoft Outlook. Contact departmental computing support or the IT Helpdesk for further information.

Outlook Web App (NEMO)

Exchange users can also use the Outlook Web App to access the service. This is referred to as NEMO. A standard web browser is required, running over a secure connection. This means your email can be accessed from anywhere. The URL to access your Exchange mailbox is:

Then logon, as prompted, with your DS username and password. Exchange 2010 brings a trastically improved web-based email experience, including full support for Firefox, Safari and Chrome, in addition to Internet Explorer. 

IMAP client

Exchange users not wanting to use either of the above methods can access their Exchange mailbox via the IMAP service presented by the server. Those people who do not use Microsoft products but do not wish to access Exchange using the web interface may use the IMAP service presented by the server.

In your preferred IMAP mail client, specify the IMAP server as and use the default server port 143. Enter your DS username in the relevant place.  Leave the password blank: your mail client should request your password when it connects to access your mail.  For the time being, your sending server should be specified as, unless you are off-campus in which case at present you will need to use the SMTP provided by your ISP.

Apple Mac Users

Apple Mac users can gain access to Exchange via either the Outlook Web App or IMAP methods. 

Further Information




Opening a shared mailbox within NEMO

Exchange 2010 only allows "opening additional mailboxes" within NEMO if the account is specified with an email address of To continue to access these shared accounts via NEMO you will need to use a URL ensuring that you reference the shared-role mailbox with


For example if the shared-role mailbox has an alias of abc12345 then the URL line would be:- 


You will then be prompted to log in, you should use your own DS username and password to access the account (Note - DO NOT open your OWN mailbox during this time).


Managing Distribution groups within Outlook

By default, Microsoft has disabled the ability to modify distribution groups for Exchange 2010 users when using the Outlook client. Whilst we plan on reviewing this restriction, the solution is to manage the distribution group within Active Directory Users & Computers. This has the bonus of displaying all members of the group (i.e. Users not visible on the GAL for example).
