outlook not connecting to office 365 server

Microsoft 365 also provides direct access to the USC calendar that is a part of your Office 365 account. Microsoft 365 only requires that you provide your email address and password for set up IMAP, however, requires additional server information. There are several advantages to setting up your email client to use “Microsoft 365”, “Office 365”, or “Exchange” rather than IMAP settings. If you are using an email client other than Outlook and Microsoft 365 or Office 365 is not a setup option, we recommend selecting the Exchange setup option and only using the IMAP (Internet Message Access Protocol) option if there is no other choice. When configuring your email client to work with your USC mailbox, we recommend selecting the Microsoft 365 setup wizard (choose when setting up Outlook). This page provides links to documentation on how to configure your email client to access Office 365.

ITS highly recommends using the Outlook email client or Outlook Web App (OWA) to access your USC Office 365 email.
