Each Outlook Express email folder that you see listed in Local Folders is stored with .dbx file extension on the hard disk, for example, Sent Items.dbx etc. All these folders are then collectively stored in Store Folder. Sometimes, DBX files might get damaged or corrupted for reasons like unexpected shutdown, antivirus scanning and others. If a suitable backup is available, you should restore from it or rename the damaged folders. The corrupted OE folders can be repaired using commercial Email Recovery solutions that are exclusively built to repair such OE folders.
To exemplify, consider you use Outlook Express as your email client to send and receive email messages. You might receive the similar error when trying to send an email message:
"Unknown error has occurred. protocol smtp, port 0, secure (SSL) NO, error number 0x800c013e
Server:'mail.yourdomain.com', Protocol POP3, Port:110, Secure (SSL): No,
Error Number 0x800C013E."
You cannot send the message after you receive this error. Trying to reproduce the behavior with different sized emails doesn't help also.
The error can also appear when you try to access your email account or Inbox.
Error 0x800C013E can occur in these cases:
1)An antivirus application is scanning and interrupting with the way OE deals with email message
2)Mail server port number or email account issues.
3)Sent Items.dbx and/or Inbox.dbx is damaged.
You can solve the existing issue by using these measures:
1) Disable and uninstall the antivirus application scanning the OE mail folders
2) Check for the correct port number as Tool | Accounts | Account Properties | Advanced
3) Try to recreate your email account and see if this helps.
4) Locate and rename the corrupted OE mail folders (Inbox.dbx and/or Sent Items.dbx). Restart Outlook Express and new empty folders will be created.
Outlook Express doesn't provide any built-in utility to repair the damaged DBX files. So, to repair them and extract data from, you are recommended to use DBX Recovery solutions. These utilities serve as perfect Email Recovery products incorporating advanced scanning algorithms to diagnose and repair damaged OE files.
