Question : Error trying to run MS Exchange

I'm not sure which topic area this  question belongs in, so I'll put it in Windows 95 general.
After installing MS Exchange and going through the setup procedure, everything seems Ok.  However, after I bring up MS Exchange and try to send a new e-mail message I receive an error message that reads "A new message could not be created.  The object could not be found - Microsoft Windows Messaging System Forms Registry 13085 - [800401F]".
I have unistalled and re-installed MS Exchange about 4 times.  I re-installed it using two different Windows 95 CD ROM disks.  
Anybody have any ideas on this?  Please let me know if you need more information about such things as how I went about doint the uninstall/reinstal.  Thanks.

Answer : Error trying to run MS Exchange

Right from MSKB.
Cannot Open or Compose Message in Windows Messaging
IMPORTANT: This article contains information about editing the registry. Before you edit the registry, you should first
make a backup copy of the registry files (System.dat and User.dat). Both are hidden files in the Windows folder.

NOTE: In this article, the term "Windows Messaging" refers to both Microsoft Exchange and Windows Messaging.

SYMPTOMS

When you attempt to start Windows Messaging or compose or open a message in Windows Messaging, you may receive
one of the following error messages:

EXCHNG32 caused an exception 05h in WMSFR32.DLL
EXCHNG32 caused an invalid page fault in module WMSFR32.DLL
EXCHNG32 caused an invalid page fault in module WMSUI32.DLL
Some information could not be read. Microsoft Exchange Client - 9992 - [81002708]
The item could not be displayed. The object could not be found. Microsoft Windows
Messaging System Forms Registry - 13085 - [8004010F]
The item could not be displayed [80004005]
The item could not be displayed [81003355]
The command you specified could not be carried out. The object could not be found. Microsoft
Windows Messaging System Forms Registry - 13085 - [8004010F]
The command you specified could not be carried out. The form cache file is not
valid. Contact your administrator. Error code 0x81003364. Microsoft Windows Messaging
System Forms Registry - 13156 - [80040119]
The Mapi spooler has shut down unexpectedly.

In addition, you may find that the long folder name associated with the Program Files\Microsoft
Exchange folder is damaged or that the Program Files folder has been renamed to $!$!$!$!.$!$.

CAUSE

This behavior can occur if any of the following conditions exists:

The Wmsfr32.dll, Wmsui32.dll, or Frmcache.dat file is missing or damaged.
The long folder name associated with the Program Files\Microsoft Exchange folder is
damaged or the Program Files folder has been renamed to $!$!$!$!.$!$.
The Exchange or MlSet values under the Hkey_Local_Machine\Software\ Microsoft registry
key are missing or damaged.

RESOLUTION

To resolve this issue, perform the following steps. After performing each step, check to see if the problem has been
resolved.

1.Verify that the Frmcache.dat file is not missing or damaged. To do so, perform the following
steps. Before performing each step, rename the Frmcache.dat file in the Windows\Forms
folder, if it exists. After performing each step, check to see if the problem has been resolved.

a. Double-click the Mlset32.exe file in the Program Files\Microsoft

Exchange folder.

b. Copy the Frmcache.bak file in the Windows\Forms folder to

Frmcache.dat.

c. Obtain a copy of the Frmcache.dat file from a computer on which

Windows Messaging is functioning properly and then copy the file to
the Windows\Forms folder on your computer.

2.Verify that the Program Files\Microsoft Exchange folder exists. To do so, attempt to locate
the folder using Windows Explorer. If the folder name that appears in Windows Explorer is
Program Files\Micros~1 or Progra~1\Microsoft Exchange, or if the Program Files folder has
been renamed to $!$!$!$!.$!$, please see the following article in the Microsoft Knowledge
Base:

ARTICLE-ID: Q143395

TITLE : Microsoft Exchange Folder Truncated to "Micros~1"

3.Rename all copies of the Wmsfr32.dll and Wmsui32.dll files on your hard disk, and then
extract new copies of the Wmsfr32.dll and Wmsui32.dll files from your original Windows 95
disks or CD-ROM to the Windows\ System folder. The Wmsfr32.dll and Wmsui32.dll files are
located in the Win95_06.cab cabinet file on the Windows 95 CD-ROM or the Win95_07.cab
cabinet file on disk 7 of your original Windows 95 disks.

For information about using the Extract tool, type "extract" (without quotation marks) at a command prompt, or
see the following article in the Microsoft Knowledge Base:

ARTICLE-ID: Q129605

TITLE : Using the Windows 95 Extract Tool (Extract.exe) NOTE: If you have
installed the Microsoft Exchange Update for Windows 95, you should not
extract new copies of the Wmsfr32.dll and Wmsui32.dll files from your
original Windows 95 disks or CD-ROM. After you rename all copies of the files
on your hard disk, you should reinstall the Microsoft Exchange Update from
the online source from which you originally installed it.

4.Verify that the Exchange and MlSet values under the following registry key are not missing or
damaged:

Hkey_Local_Machine\Software\Microsoft

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall
Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can
be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the Changing Keys And Values online Help topic in
Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and
User.dat) before you edit the registry.

The Exchange value should have the following value:

C:\Progra~1\Micros~1\exchng32.exe

The MlSet value should have the following value:

C:\Progra~1\Micros~1\mlset32.exe

If either of these values is missing or incorrect, create or modify the value manually.

5.Remove and reinstall Microsoft Exchange. To do so, follow these steps:

a. In Control Panel, double-click Add/Remove Programs.

b. Click the Windows Setup tab and then click the Microsoft Exchange

check box to clear it. If you are prompted to remove Microsoft Fax
also, do so.

c. Click OK.

d. After Microsoft Exchange is removed, remove all files in the

Windows\Forms folder and then restart Windows 95.

e. In Control Panel, double-click Add/Remove Programs.

f. Click the Windows Setup tab and then click the Microsoft Exchange

check box to select it. If you also removed Microsoft Fax, click
that check box to select it also.

g. Click OK.

MORE INFORMATION

The Frmcache.dat file is created during the initial configuration of Windows Messaging, either by the Microsoft Exchange
Setup Wizard or later when you add the first service. The Frmcache.dat file contains standard forms and other
information that Windows Messaging uses to perform tasks such as displaying and sending messages. If the information
associated with a particular task is missing or damaged, you receive an error message when you attempt to perform that
task. If all other information in the file is not damaged, Windows Messaging appears to function properly when
performing all other tasks.

The size of a valid Frmcache.dat file is usually 16K or larger. Many programs add information to the Frmcache.dat file
when they are installed, causing the file to increase in size. The Frmcache.bak file is created when the Frmcache.dat file is
first created and is typically not modified when a program adds information to Frmcache.dat file. Therefore, if you
replace the Frmcache.dat file with the Frmcache.bak file, any information added to the Frmcache.dat file is lost. This
information must be replaced manually by reinstalling the program that originally added it.

The following situations can cause the Frmcache.dat file to become damaged:

You backed up and restored the files on your computer, but long file names were not
recognized correctly. After the files were restored, the path for the Program Files\Microsoft
Exchange folder did not match the associated registry entries.
Your computer contains a preinstalled copy of Windows 95. When an image of Windows 95 is
placed on a hard disk, Windows Messaging may appear to be installed correctly, but the
Frmcache.dat file may not have been created correctly.

The Microsoft Exchange Configuration Wizard (Mlset32.exe) is run for the first time when Windows
Messaging is first installed. It can be used as a troubleshooting tool after Windows Messaging has
been installed, but it is not always successful in rebuilding the Frmcache.dat file.
