How to repair email database PST related problems in Microsoft Outlook for Windows

Are you facing issues while opening emails in Windows outlook? Have you faced problems opening outlook for Windows? Does outlook give error message related to pst database corruption at startup?

Outlook for Windows also provides an Inbox repair tool (Scanpst.exe) to repair and recover corrupted items in email database just like Outlook for Mac has an option to rebuild database.
