When you graduate from OWU, you have the opportunity to convert your BishopApps account to Email-for-Life, which preserves all of your data. If you don’t do this, ALL of your data may be permanently DELETED. That includes all your BishopMail, contacts, calendar entries, Docs, Sheets, Slides, Forms, Sites, and all files stored in Drive.
Be on the watch for an email notice that your account may be removed in the month or two after graduation. See the E-mail for Life (EFL) page for a typical timeline.
