Find the Microsoft Outlook Temporary folder

We often get calls from customers saying that they have worked on an attachment in Outlook and saved it but are not able to find it again.  This is because Outlook saves attachments to a temporary folder on your computer which is hidden.

We also get calls saying that Outlook is running very slowly or that they are unable to open certain attachments within Outlook.  This is normally down to the fact that the Outlook temporary folder has a lot of files within in and needs clearing out.

To find the location of the Outlook Temporary folder you need to do the following;

Open the Windows registry using regedit.exe and then browse to the following location depending on the version of office you have;

Outlook 2000 HKEY_CURRENT_USER Software Microsoft Office9.0 Outlook Security
Outlook 2002/XP HKEY_CURRENT_USER Software Microsoft Office10.0 Outlook Security
Outlook 2003 HKEY_CURRENT_USER Software Microsoft Office11.0 Outlook Security
Outlook 2007 HKEY_CURRENT_USER Software Microsoft Office12.0 Outlook Security
Outlook 2010 HKEY_CURRENT_USER Software Microsoft Office14.0 Outlook Security

Once there you need to open the value called OutlookSecureTempFolder to find the folder location.

The easiest way to browse to this folder is to simply copy this path and paste it into either into start and run (in Windows XP) or start and search (in Vista or Windows 7.)

Now that you can access this folder you can either get the attachments your need or delete the content to clear out the folder.
