To store emails, calendar, contacts, etc., on local storage, Outlook uses Personal Storage Table (PST) file format. Every email account created or added to Outlook has a PST file. When the PST file gets damaged or corrupted due to various reasons like the large size of the files, virus infection, abrupt shutdown of the device/application, bad sectors on the storage device, or accidental deletion, it becomes inaccessible.
Microsoft Outlook has the inbuilt Scanpst.exe (Inbox Repair Tool) to scan & repair damaged/corrupt PST files. Sometimes scanpst.exe cannot be found when Outlook is installed from Microsoft Store. And sometimes, it does not work or fails to repair corrupt PST files, as Scanpst.exe can repair files up to 2GB only. Also, this tool may fail when the extent of corruption of PST files is severe.
In all the above situations, you need a good third-party tool. And we recommend Kernel for PST Repair for all such needs.
It is an efficient tool to recover complete data from the user mailbox, including inbox, contacts, drafts, journals, tasks, deleted items, Outlook notes, etc. It has a very simple GUI, and it not only repairs mailbox data by removing corruption but also protects the data while doing so. Once you have recovered data from the PST file, you have a choice to save the same to Office 365, Exchange Server, Outlook PST & Gmail. And it supports all versions of Outlook.
This tool works in 3 simple steps, viz. Select> Preview> Save.
After launching the Kernel for Outlook PST Repair tool, you can select Recover Single File or Recover Multiple File as per your need.

And finally, to save the recovered data, select the required saving option from the list of the saving option(s) given on the right. You can proceed to filter the PST data and then save it in the selected destination by following the on-screen instructions.
To avoid the corruption of large files, it automatically splits large-sized PST files into smaller sizes like 1GB/1.5GB/2GB/2.5GB. You have various options to save your recovered emails in formats like DBX, MBOX, MSG, EML, TXT, RTF, HTML, MHTML & PDF, etc. You can also save PST files to Office 365 or email servers like Exchange Server, Lotus Domino (IBM Domino), or webmail clients like Gmail, Yahoo, iCloud, and company IMAP accounts.
