OutlookTempCleaner gives you easy access to the Temp folder that Microsoft Outlook uses to open attachments as well as the option to automate maintenance with Windows’s Scheduled Tasks.

Command-line options are also available. They are:

-emptyfolder
If you want to automatically empty the folder via a logon or logoff script or task, you can use the -emptyfolder switch. This is particularly handy for shared domain computers. You can basically set it and forget it and not worry about leaving sensitive files, your hard disk filling up or suddenly running into errors when you often deal with attachments with the same name.

-openfolder
As the OutlookSecureTemp folder location is different for each user there is no way to deploy a single shortcut.

With OutlookTempCleaner you can create a shortcut with the -openfolder startup switch to directly open the OutlookSecureTemp folder. The result is that you can deploy a standardized shortcut and allow users easy access to the folder.

-foldersize
With the -foldersize startup switch you can create a scheduled task (for instance; run once per week) to inform you of the current size of the folder. This way you can easily keep track of its size and empty it when you think it is getting too big.
