How to Repair OST file using scanost.exe

An OST file or ‘.ost’ is an offline folder file in Microsoft Outlook that contains almost every data related to e-mails, like e-mail messages, journals, notes, drafts, folders, posts, appointments, contacts, tasks, meeting requests, distribution lists, task requests, calendar (planner), attachments etc. This folder allows users to work offline. Outlook synchronizes the changes made in the OST file with the Exchange server the next time it connects. However, OST might get corrupted due to few possible reasons, resulting into inaccessibility of Outlook.
Outlook may display error message “Facing error code 003” while accessing it, which means user should immediately repair OST file.
