Outlook: How to repair corrupted PST and OST files

Microsoft Outlook is a personal information manager for emails, calendars, and contacts. Outlook emails may contain crucial information, such as meeting schedules and contacts, so it is wise to back them up. You can do so by creating an archive. While offline, you can also access your backed-up files through the Cached Exchange Mode on your computer. Just note that these are reserved mainly for the desktop version and don't include your Chromebook (your Chromebook relies on Outlook.com).
