Exchange Online

Microsoft's Exchange Online, which includes email, calendar, contacts and tasks, is available to all students and eligible staff in the University. Use the Outlook client or Outlook Web App to access your intergrated email, calendar and tasks, or set up your preferred email client to access just your Exchange Online mailbox.

What is Exchange Online?

Microsoft Exchange Online is a cloud-based messaging solution that supports email, calendar, contacts and tasks. It is integrated with the Microsoft 365 collaboration environment.

Your University email account

The University Exchange Online Email Service is provided to all matriculating students, and staff employed by The University of Cambridge.

New students

Email accounts for new students are created in advance of their arrival.

Some students may also be given an institutional Microsoft account by their Department or College. Please see information provided by your local IT staff.

University staff

If you are employed directly by the 'core' University, your Department or institution will request an email account from UIS for you so that it is ready on your arrival.

College and affiliated institutional staff

Some Colleges and affiliated institutions have chosen to join the University's Enrolment for Education Solutions (EES) Agreement and their staff are also eligible for a University Exchange Online email account.

Other institutions may have their own Microsoft Agreement in place and are not part of the University's centralised arrangements. Speak to your local IT support staff about how to get your @cam email account.

      Hermes users: migrate yourself to Exchange Online

If you arrived at the University before 2018, you might still have a Hermes email account for your email. The Hermes email service is being decommissioned and will close by the end of December 2021. From then onwards, the only university-wide email service provided and supported by UIS will be Exchange Online.

UIS is currently working with the Collegiate University to plan and action the closure of Hermes by December 2021. You may want to talk to your local IT staff to see what their plans are for moving away from Hermes and when they plan to do so.

As an individual user, you can self-migrate your personal Hermes mailbox (i.e. your email) to Exchange Online at any time, if you want to. Migrating your Hermes account to Exchange Online offers tangible benefits:

  • allows you to use the Calendar tool in Microsoft Teams to schedule online Teams meetings
  • 100GB quotas per mailbox
  • send emails up to 150MB each
  • integrates your email, calendars, contacts and tasks
  • provides a modern web interface
  • dedicated Outlook mobile apps for iOS and Android devices.

You can migrate your University email to Exchange Online yourself:
