Symptoms

When you use an HTML-based page to automatically create email messages in Microsoft Outlook, the message's Subject line and body may not be created.

Cause

This issue occurs if your computer doesn't have the following registry key:

HKEY_CURRENT_USER\Software\Clients\Mail

If you have the most recent versions of Internet Explorer or Microsoft Edge installed, you must have this registry key on your system.

Resolution

Warning

If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, use Registry Editor to manually add the HKEY_CURRENT_USER\Software\Clients\Mail registry key. To do this, follow these steps:

    Windows 8 and Windows 10: Press the Windows Key + R to open a Run dialog box. Type regedit.exe, and then click OK.

    Windows 7 and Windows Vista: Click Start, type regedit in the Start Search box, and then press Enter. If you're prompted for an administrator password or for confirmation, type the password, or click Allow.

    Windows XP: Click Start, click Run, type regedit, and then click OK.

  3. Locate the following registry key:

    HKEY_CURRENT_USER\Software\Clients

    1. Select the Clients subkey.
    2. On the Edit menu, click New -> Key.
    3. Type Mail, and then click OK.
    4. Exit Registry Editor.
