Does USC Web Mail have a time-out feature?
As a security feature of USC Web Mail, your session will time out if it is idle for 60 minutes. You will be automatically logged out if there is no activity in your USC Web Mail window(s) for 60 minutes or more. If your USC Web Mail session times out, login again. Note: The time you spend writing an email message does not count as activity. Therefore, your session may time out if you spend more than 60 minutes composing a message. When this happens, you may lose the message you were composing if you haven’t saved it as a draft. To prevent losing a message you are writing, periodically click the Save Draft icon in the Compose window.
