This behavior may occur if either of the following conditions is true:

• You import mail from Outlook into Outlook Express, but you removed Outlook from your computer before you tried to import the mail into Outlook Express.

• You configure Outlook Express to be the default Simple Messaging application programming interface (MAPI) client.

• You import or export mail from Outlook Express, and you do not have Outlook installed on your computer.

To resolve this issue, try one of the following methods, as appropriate for your situation.
