256986 Description of the Microsoft Windows Registry
After you install the Prodigy version 5 software, or any other Internet service provider (ISP), you may experience the following e-mail related symptoms:
- The Page by E-mail and Link by E-mail commands under the Send command on the File menu in Microsoft Internet Explorer may not work.
- The Read Mail, New Message, Send a Link, and Send Page commands under the Mail button in Internet Explorer may not work.
- When you try to use any of the preceding commands, your pointer may become an hourglass (indicating your computer is busy), but nothing may happen and you may not receive an error message.
This issue occurs because the Prodigy software, or any other ISP, adds an e-mail client key to the HKEY_CURRENT_USER and/or the HKEY_LOCAL_MACHINE branches in the registry that does not contain any values. When you use a command listed earlier in this article, Outlook Express checks this registry key, but does not find information about an e-mail program to start, and generates the symptoms listed earlier.

However, if you connect with Prodigy, or other ISP's, and then use Outlook Express as your primary e-mail client, the key is not recreated.
NOTE: If the registry key does not exist, create the String Value DLLPath in the following registry key:
To create the registry key, perform the following steps:
- Right-click the Mail folder, point to New, and then click String Value.
- Type DLLPath, and then press ENTER.
