When you open up Outlook Express you get the following error message:
An unknown error has occurred. Protocol: SMTP, Port: 0, Secure SSL: No, Error 0x800c0131Ce problem may be due to corruption or lack of Folders.dbx file.
- To solve this, simply restore the file Folders.dbx.
- Search for Folders.dbx using the search tool(Start/Find/Files or Folders).
- Rename the file to make a backup, for example Folders.bak.
- Launch Outlook Express. Folders.dbx file is automatically recreated and the application opens correctly.
