When you start Outlook Express or try to send an e-mail message, you may get 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

The usual cause of this error is a missing or damaged folders.dbx file. Either that or it is using a read only attribute. To fix this bug:

• Click Start
• then Find
• then click Files or Folders.
• In the Named box, type folders.dbx.
• In the Look In box, click your main hard disk (this is usually drive C), and then click Find Now.
• Right-click the Folders.dbx file, and then click Rename.
• Type folders.old, and click OK.
• Start Outlook Express again. This creates a new Folders.dbx file automatically.
