A personal Storage (PST) file contains local copies of emails, contacts, tasks and more. The user can easily import or export the PST data from Outlook Express by using File->Import/Export->Messages->Microsoft Outlook. For instance a user attempts to import the PST data and receives the following error message:

“Messages cannot be imported from the MAPI client. An error has occurred”

Three main reasons for the occurrence of this error message can be – removing Outlook from the computer system before the user tried to import the mail into Outlook Express, the user does not have Microsoft Outlook installed on the computer system or the user configures Outlook Express to be the default simple Messaging Application Programming Interface (MAPI) client.

To solve the above three issues, the user can take the following measures:

• Reinstall MS Outlook
• Change the MAPI settings while importing the file.
• If problem is being encountered in Windows Mail using Windows Vista, then this might be a PST of Outlook 2002 or earlier versions, which has a problematic interaction with it.

The user can solve this by initially importing the PST into Outlook Express on using Windows XP, then copy the Outlook Express file to the targeted Vista system and then import it in Windows Mail.

Failure in importing a PST can also occur due to PST corruption. The main reasons for PST corruption include virus attack, software malfunctioning and more.
