OL2000: The 'Clear Cache' Button Does Not Clear the Forms Cache (324130)


The information in this article applies to:

  • Microsoft Outlook 2000
This article was previously published under Q324130

SYMPTOMS

If you try to open an item that is based on a custom form, Outlook 2000 may display the item in one of the standard forms instead of using the custom form.

If you click the Clear Cache button, Outlook 2000 continues to render the item in the standard form.

CAUSE

This problem occurs because Outlook 2000 cannot locate the custom form definition and adds an entry to the Frmcache.dat file that maps these items to a standard form.

RESOLUTION

To resolve this problem, obtain the latest service pack for Microsoft Office 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

276367 OFF2000: How to Obtain the Latest Office 2000 Service Pack

A supported fix is now available for the Clear Cache button to allow these entries to be removed from the Frmcache.dat file.
The English-language version of this fix should have the following file attributes or later: 
   Date           Time   Size       File name     
   -------------------------------------------------------
   17-Jun-2002    03:55  2,673,152  Outlook.msp
   17-Jun-2002    04:01  7,716,352  Outlook_admin.msp
After the fix is installed, the English-language version of this fix will have the file attributes (or later) that are listed in the following table. The dates and times for these files are listed in coordinated universal time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel. 
   Date           Time   Version      Size      File name     
   -------------------------------------------------------
   20-May-2002    13:29  8.30.3151.0  779,024   Outex.dll

WORKAROUND

This problem does not occur when you work with forms that are published in the Organizational Forms Library because the forms that are published to the Organizational Forms Library are available to all items.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
This problem was first corrected in Microsoft Office 2000 Service Pack 3 (SP-3).

MORE INFORMATION

The Clear Cache button does not clear the entry, and to resolve this problem, you must delete the Frmcache.dat file.

For Outlook 2000 to locate a custom form definition, the form must be published to the current folder, the Personal Forms Library, or the Organizational Forms Library. Outlook 2000 finds the custom form definition if the form has already be cached, but solutions should not be designed to rely on the cache as a forms library.
