Windows Email is the email-client of Windows Vista. It is basically a replacement of Outlook Express, but is not a component of Internet Explorer. The application allows you to use Microsoft Outlook mails once you import the associated PST in it. For this to accomplish successfully, Windows Mail requires that .pst file should be free from errors. It cannot import PST that is corrupted and unreadable. To import the file, you will first need to repair it, which is best possible using Outlook Inbox Repair Tool or third-party PST Recovery software. However, there can be other reasons too that might prevent the PST file from importing.For example, suppose you try to import your PST in Windows Mail. The import operation may fail with one of the below symptoms:

You receive an error suggesting that email cannot be imported from MAPI client.
You attempt to import Outlook contacts in Windows contacts but fail
When you click to import, the process hangs with no clue

Cause

Some possible reasons causing this behavior are as follows:

Microsoft Outlook is not installed on the computer on which the PST is stored
You are trying to export Outlook contacts without comma separated values text file to Windows contacts
The Outlook PST you are trying to import is corrupted

Solution

You should try implementing these solutions to import your PST in Windows Mail:
