Outlook Error Message: Can't create file...

This error message graced me with its presence again this week so I thought I would put out the quick fix in the case that anyone else might have been as blessed.


Error Message:
 
"Can't create file: FILE NAME.doc. Right-click the folder you want to create the file in, and then click Properties on the shortcut menu to check your permissions for the folder."

Cause:

Microsoft Outlook uses a temporary folder to save and open the attachments. 
By default that folder is: C:\Users\%Username%\Local Settings\Temporary Internet Files\OLK#\ (where # is a random number). Some of the security updates for Windows going back as far as 2000 rewrite the past statement in the registry and prevent the file from being created in that folder. The solution is correct the path statement to one that exists. 

Solution:

1. Run Regedit
2. HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security
3. Note: Depending on your version you may have to modify that path after the "Office" key. You may have folders 8.0, 9.0, 10.0, 11.0, or 14.0 go the highest number. This is probably the version that you use.
4. Modified the Key "OutlookSecureTempFolder", by replacing "Temporary Internet Files" with "Temp". Right click on this item and select 'Modify'.
5. Restart Microsoft Outlook.

For example:


Windows XP 
OLD VALUE: C:\Documents and Settings\%Username%\Local Settings\Temporary 
Internet Files\OLK177\ (you may have different number than 177) 
NEW VALUE: C:\Documents and Settings\%Username%\Local Settings\Temp\OLK177\ 


Windows Vista and 7 
OLD VALUE: C:\Users\%Username%\Local Settings\Temporary 
Internet Files\OLK177\ (you may have different number than 177) 
NEW VALUE: C:\Users\%Username%\Local Settings\Temp\OLK177\
