When trying to look at or save Outlook attachments, you may get an error pop up stating that you do not have permissions to save, this is due to the temporary folder that Outlook uses to store attachments when opening them is full.
To fix this issue, you have two options. You could empty the Outlook temporary folder which is stated in the following registry key:
Value = OutlookSecureTempFolder
However, you can also point your Outlook temporary files to a different location should you wish. Just simply change the OutlookSecureTempFolder location and reboot your machine.
