Configuring Your Email Client for Office 365 – IT Services

We recommend using the Outlook email client or the Outlook Web App (OWA) to access your USC Office 365 email. this page provides links to documentation on how to set up your email client to access office 365. when setting up your email client to work with your usc mailbox, we recommend selecting the microsoft 365 setup wizard (choose at configure Outlook). if you are using an email client other than outlook and microsoft 365 or office 365 is not a configuration option, we recommend selecting the exchange configuration option and only using the imap (internet message access protocol) option if there is no other option.

exchange vs. imap

There are several benefits to configuring your email client to use “Microsoft 365”, “Office 365”, or “Exchange” instead of the IMAP setting. Microsoft 365 only requires you to provide your email address and password for setup; imap, however, requires additional information from the server. Microsoft 365 also provides direct access to the USC calendar that is part of your Office 365 account.

If you use Microsoft Outlook as your email client, you must use the default Microsoft 365 account type. At this time, it also supports connecting to other compatible mail clients using the exchange and imap4 connection methods with oauth2, although exchange is preferred.
