ScanPST Fails To Repair OST File? Here Are Some Fixes That You Can Try
Microsoft Outlook is a personal information manager that is shipped with Microsoft Office. When users run Outlook for the first time, two necessary data files gets created automatically i.e., OST and PST. Personal Storage Table (PST) acts as the main storage of all the database in Microsoft Outlook. Whereas Offline Store Table (OST) is a synchronized copy of email messages stored on a server that can be accessed using Outlook application. The OST file lets users work in the offline mode, which means users can finish their tasks even without internet connectivity. When the connection establishes again, the OST file gets automatically synchronized with Exchange Server.
But, these OST files are highly prone to corruption or damage. Sometimes, when OST file is getting synchronized, users may receive errors. Or, after completing the sync process, they may find that some items are deleted or missing from OST file. In case of OST file corruption, the user can try the inbuilt utility present in Microsoft Outlook which is Scanpst.exe. But sometimes the ScanPST fails to repair OST file data.
