How to access and log in to your Exchange Online mailbox using either the Outlook Web App (webmail), Outlook or other email clients.

How to log in to your Exchange Online mailbox

However you choose to connect to your Exchange Online mailbox, you will be asked to sign in to your University of Cambridge Microsoft account using these credentials:

  • Username =
  • Account type = Work or School account
  • Password = your University account password (formerly Raven)

How to access your Exchange Online mailbox

Webmail: the Outlook Web App (all users, including Linux)

Open a web browser and go directly to the Outlook Web App (OWA) or via the Microsoft 365 portal:

If you ever experience problems using the Outlook desktop client, you can usually still get to your email in your browser using the OWA.


Use the Outlook email client and/or mobile app (PC, Mac, iOS, Android)

We suggest using the Outlook email client because it gives you integrated access to your email, personal and shared Exchange Online calendars, your To Do list and your OneDrive personal filestore.

Outlook is designed to work seamlessly with other products in the Microsoft 365 collaboration environment including the Office 365 apps and Teams which makes scheduling meetings and collaborating with others across the Collegiate University much easier:

Set up Outlook for PC
Set up Outlook for Mac
Set up Outlook for Android
​​​​​​Set up Outlook for iOS

Outlook for Android requires Android version 8.0 or above. Devices using Android 7.1 and below that have previously installed the Outlook app will not receive updates to the app. (From 10th July 2023 Outlook for Android will require Android 9.0 or above)


Configure another email client (all users, including Linux)

If you don't want to use the Outlook Web App or Outlook email client, you can configure another email client to connect to your University Exchange Online mailbox using the settings information below. However, we are unable to provide support for other clients.

You will need to connect to your personal Exchange Online Calendar separately, using your choice of calendar application.

The use of Apple Mail and Calendar with Exchange Online often leads to unpredictable bugs and unintended behaviour.

For this reason, we discourage the use of Apple Mail and Calendar with Exchange Online and strongly recommend using the Outlook Web App or Outlook for iOS or Mac instead.

If you are not going to use Outlook, where possible, please upgrade iOS to the latest version to minimise any unexpected behaviour when using Exchange Online email.

Basic Exchange Online productivity and collaboration functionality is provided natively by iOS, but please be aware that:

  1. Mail may take a long time to index emails for large mailboxes after migration or to complete bulk email moves between mailboxes.
  2. Shared Mailboxes are not supported by iOS Mail.
  3. Editing Calendar entries may lead to duplicated events.
  4. Calendar may not exhibit the correct behaviour when cancelling an event in a series.
  5. There is minimal integration with other Microsoft 365 services such as Teams.
  6. Additional functionality provided by Microsoft 365 may not be available in iOS native applications.

For instructions, see Set up an Outlook account on the iOS Mail app or Set up email in Mac OS X Mail on Microsoft's support site.
