This article was previously published under Q176338 SYMPTOMS
An application using the MSMAPI32.OCX MAPIMessages Control (version
5.00.3721) may hang when the .Fetch method of the control is called.
CAUSE
The messaging subsystem of your Operating System may be too outdated to use
this control successfully.
The most common occurrence of this problem is where the customer has
installed the Exchange 4 client from the original release media of Windows 95.
RESOLUTION
To resolve the problem, you can install the Windows Messaging System (WMS).
If the problem is on Windows 95, WMS can be installed from
ftp://ftp.microsoft.com/Softlib/MSLFILES. The target file is called
EXUPDUSA.EXE. This will update the messaging subsystem (MAPI DLL files) on
the problematic system.
If the problem is on another platform, you can obtain the appropriate WMS
from ftp://ftp.microsoft.com/developr/MAPI/WMS_RDST. The README.TXT file in
that directory provides information on what file to download for operating
system as well as installation instructions.
STATUS
This behavior is by design.
MORE INFORMATION
This article is not applicable if the problematic system has (or previously
had) any version of Outlook or the Exchange client version 5 or higher
installed.
