Error opening attachments in Outlook saying "Access Denied" & Check Permissions

Hebrew Error:

"אין אפשרות ליצור את הקובץ: filename.tif. לחץ באמצעות לחצן העכבר הימני על התיקייה שבה ברצונך ליצור את הקובץ ולאחר מכן לחץ על 'מאפיינים' בתפריט הקיצור כדי לבדוק את ההרשאות שלך עבור התיקיה."

When opening an attachment directly from within Outlook you could get an error message saying that it can’t create the file and to that you need check the permissions on the folder you want to save it in. In most cases the permissions on the folder isn’t the issue but the fact that the folder is "full". When you open an attachment directly from within Outlook it will first save a copy to a subfolder of the Temporary Internet Files folder. Cleaning out the folder will solve the issue.

The special folder where outlook temporarily saves the file for opening is listed in the registry.

Locate the folder path:

Outlook 97	HKEY_CURRENT_USER\Software\Microsoft\Office\8.0\Outlook\Security
Outlook 98	HKEY_CURRENT_USER\Software\Microsoft\Office\8.5\Outlook\Security
Outlook 2000	HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook\Security
Outlook 2002/XP	HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security
Outlook 2003	HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security
Outlook 2007	HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security

Go to the folder:

1. Open the OutlookSecureTempFolder registry key from the location provided in Step 1.
2. Copy the path from the key.
3. Open Explorer
4. Paste the address in the Address Bar and press Enter 
5. Empty the folder.
