Error When Opening Attachments In Outlook

In Outlook 2003, 2007, 2010 and 2013 you receive the below error when trying to open an attachment;

"Outlook 2010 Cannot Create File, Right-click the folder you want to create the file in, and then click properties on the shortcut menu to check your permissions to the folder"

 

Solution:

Open the registry editor (Start-Run-REGEDIT) and find the following keys;

 

Outlook 2003

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

Value Name: OutlookSecureTempFolder
Data Type: REG_SZ

Outlook 2007, 2010 and 2013

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

Value Name: OutlookSecureTempFolder
Data Type: REG_SZ

 

The OutlookSecureTempFolder key contains the path to the Secure Temp Folder, so all you have to do is copy the path and paste it into a Windows Explorer window and press enter.

 

Once the folder opens, select all files (CTRL+A) and delete them.

 

NOW DON'T WORRY! You haven't deleted the files, just the temporary copies :)

 

Restart outlook and your problem should be solved!
