Attachment issues in Outlook 2010, Outlook 2007, or Outlook 2003

 Error

Cannot create file: file name. Right-click the folder that you want to create the file in and then click Properties on the shortcut menu to check your permissions for the folder.

Cause

This problem occurs for one of the following reasons:

* The temporary files or the temporary secure folders that the files are located in cannot be deleted or removed while the attachments are open.

* The Temporary Internet Files folder is stored on a server on which you do not have sufficient permissions.

* The Temporary Internet Files folder is full

Resolution

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 first tries to use a temporary file, it examines the registry to determine whether the following value exists, depending on your version of Outlook:

HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\Security

or

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\xx.0\Outlook\Security

Where xx.0 is 14.0 for Outlook 2010, 12.0 for Outlook 2007, and 11.0 for Outlook 2003.

Value Name: OutlookSecureTempFolder

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

If the registry value does not exist, or if the value points to an invalid location, Outlook 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: Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.
