File Description Stores preferences for the e-mail server used by MSN; installed with MSN software and required for MSN to check and send e-mail; typically named "MSN#.mailhost."

If the Mailhost file is corrupt or missing, the MSN software may display a "Mailhost File" error; to recover the Mailhost file, first select "Run..." from the Windows Start menu; then type the following in the text box:

regsvr32 c:\progra~1\msn\msncorefiles\mailui.dll

This should restore the Mailhost file and allow MSN to communicate with the mail server again.
