Symptoms

You exit Microsoft Office Outlook 2010, Microsoft Office Outlook 2007, or Microsoft Office Outlook 2003 while email attachments are open. These attachments are from email messages that are in a secure Outlook folder. Alternatively, Outlook unexpectedly closes.

When this occurs, the attachments remain in the "Outlook Secure Temporary File" folder. This occurs even if you close the attachments after you exit Outlook.

Additionally, if you open the attachment to the email message from the Reading pane, you do not receive a prompt to save changes when you exit Outlook.

Cause

This problem occurs because Outlook 2010, Outlook 2007, and Outlook 2003 cannot remove the temporary file or dispose of the secure temporary folder while the attachments are open.

Resolution

This problem has been resolved in Microsoft Outlook 2010 Service Pack 1 (SP1) and in the Microsoft Office Outlook 2007 hotfix package dated June 29, 2010. These updates are described in the following Microsoft Knowledge Base articles.

More information

When you open file attachments that are considered safe, Outlook 2010, Outlook 2007, and Outlook 2003 puts these attachments in a subdirectory of the Temporary Internet Files directory as an additional precaution. When Outlook 2010, Outlook 2007, or Outlook 2003 first tries to use a temporary file, it examines the registry to determine whether the following value exists, depending on your version of Outlook.

Outlook 2010
HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security

or

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\Security

Value Name: OutlookSecureTempFolder
Data Type: REG_SZ

Outlook 2007
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security

or

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\Security


Value Name: OutlookSecureTempFolder
Data Type: REG_SZ

Outlook 2003
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security

or

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Outlook\Security


Value Name: OutlookSecureTempFolder
Data Type: REG_SZ

If the value exists, and if the value contains a valid path, Outlook 2010, Outlook 2007, or Outlook 2003 uses that location for its temporary files.

If the registry value does not exist, or if the value points to an invalid location, Outlook 2010, Outlook 2007, or Outlook 2003 creates a new subdirectory under the Temporary Internet Files directory and then puts the temporary file in the new subdirectory. The name of the new subdirectory is unknown and is randomly generated, depending on your version of Outlook. In this situation, to locate this subdirectory, depending on your version of Windows and your version of Outlook, follow these steps.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
