OL98: (IMO) Error finding AWFEXT.ECF While Starting Outlook

When you start Microsoft Outlook 98 under Microsoft Windows 98, you may get the error message: If you quit Outlook, you get the error message:

You have installed the Microsoft Fax software from the Windows 98 compact disc.

The versions of MAPI files installed by Outlook 98 Internet Mail Only (IMO), are different than the ones required by Microsoft Fax. The installation of Microsoft Fax does not overwrite these MAPI files during set up. When Outlook is started and the Microsoft Fax service attempts to start it fails, generating the error.

If you need Fax capability with Outlook 98 (IMO), you will need to uninstall Microsoft Fax and then install the Symantec WinFax Starter edition.

To Uninstall Microsoft Fax

1. Click Start, Point to Settings, and then click Control Panel.
2. Double-click to open Add/Remove Programs.
3. Click to select Microsoft Fax and then click Add/Remove.

Outlook will now start without error.
