SYMPTOMS

DAO programs that rely on the functionality of DAO versions greater than 3.50.3428 might not function correctly after you perform a full install of Outlook 98. For example, if a Visual Basic version 5.0 or 6.0 applications, or Visual C++ version 5.0 or 6.0 applications use DAO and Outlook 98 is installed, the DAO application might fail to function properly.

CAUSE

Outlook 98 incorrectly installs DAO. It places an older version (3.50.3428) of DAO in the \Windows\System directory and registers DAO to use it. The newer version that was installed in the \Program Files\Common Files\Microsoft Shared\DAO directory is left untouched, but the registry settings for DAO map to the older version.

RESOLUTION

On the Start menu, select Run and type in the following command:

regsvr32 C:\Program Files\Common Files\Microsoft Shared\DAO\DAO350.DLL

This restores the registry settings for DAO so that the newer DAO components (the files in the Microsoft Shared\DAO folder) are used.

STATUS

Microsoft has confirmed this to be a bug in Outlook 98.
