SYMPTOMS
========

The Microsoft Mail PostOffice icon in Control Panel is missing. The icon may not
appear even after removing and adding Windows Messaging through Windows NT
Setup.

CAUSE
=====

This behavior occurs because the Microsoft Mail component has not been
installed. This behavior can also occur after having Microsoft Outlook profiles
installed on the system that did not use the Microsoft Mail postoffice.

RESOLUTION
==========

To resolve this problem, install the Microsoft Mail component.

When you install the Microsoft Mail component, Setup also installs the Microsoft
Mail PostOffice Control Panel extension file, Wgpocpl.cpl, into the
<systemroot>\System32 directory.

1. Click the Start button, point to Settings, and then click Control Panel.

2. Double-click Add/Remove Programs.

3. Click the Windows NT Setup tab.

4. Select Windows Messaging from the Components list, and then click Details.

5. Select the Microsoft Mail check box, and then click OK.

6. Click OK on the Windows NT Setup properties page, and follow the on-screen
  directions for installing the Microsoft Mail component.

NOTE: If you do not close and reopen Control Panel after you have installed the
Microsoft Mail component, you may need to click Refresh on the View menu of
Control Panel to see the addition of the Microsoft Mail postoffice icon.

To add the Postoffice icon when Outlook profiles are installed that do not use
the Microsoft Mail postoffice:

1. Back up any mail folders currently in use.

2. Remove any components of Windows Messaging in Windows NT Setup.

3. Start Registry Editor (Regedt32.exe).

4. Go to the following location in the registry:

  HKEY_CURRENT_USER\Software\Microsoft\WindowsNT\CurrentVersion\Windows
  Messaging Subsystem
  NOTE: The registry key above is all one path; it has been wrapped for
  readability.

5. On the Registry menu, click Save Key.

6. Delete any profiles found under the following registry key:

  HKEY_CURRENT_USER\Software\Microsoft\WindowsNT\CurrentVersion\Windows
  Messaging Subsystem\Profiles\MS Exchange Settings NOTE: The registry key
  above is all one path; it has been wrapped for readability.

7. Restart your computer, and then add the Windows Messaging components through
  Windows NT Setup again.

8. Close, and then open Control Panel to refresh the icons.
