SYMPTOMS

When you start Outlook Express or attempt to send an e-mail message, you may receive one of the following error messages:
  • MSIMN caused an invalid page fault in module Msoe.dll
    MSIMN caused an invalid page fault in module "unknown"
    MSIMN caused an invalid page fault in module Directdb.dll
    Msimn caused an exception C0000006h in module Directdb.dll
    Outlook Express: The message could not be sent. There is not enough Disk space.
    Unknown error has occurred. Protocol: SMTP Port: 0 Secure: No [SSL] Error: 0x800c0131

CAUSE

This behavior can occur if the Folders.dbx file is missing, damaged, or using the read-only attribute.

RESOLUTION

Rename the Folders.dbx file:
  1. Click Start, point to Find, and then click Files or Folders.
  2. In the Named box, type folders.dbx.
  3. In the Look In box, click your primary hard disk (usually drive C), and then click Find Now.
  4. Right-click the Folders.dbx file, and then click Rename.
  5. Type folders.old, and then click OK.
  6. Start Outlook Express. This creates a new Folders.dbx file automatically.
