Are in a situation to asking yourself that Where does the Outlook creates Temporary folder better known as the OLK folder? Or, where does Microsoft store temporary data such as attachments? Where the heck is that Old OLK folder?
Depending on your operating system, version of Outlook AND user logged in, the OLK temporary folder will be created in a different places. To find where it’s been created, open the Windows registry using regedit.exe and look for the Registry key OutlookSecureTempFolder using the list below:
Outlook 97 – HKEY_CURRENT_USERSoftwareMicrosoftOffice8.0OutlookSecurity
Outlook 98 – HKEY_CURRENT_USERSoftwareMicrosoftOffice8.5OutlookSecurity
Outlook 2000 – HKEY_CURRENT_USERSoftwareMicrosoftOffice9.0OutlookSecurity
Outlook 2002/XP – HKEY_CURRENT_USERSoftwareMicrosoftOffice10.0OutlookSecurity
Outlook 2003 – HKEY_CURRENT_USERSoftwareMicrosoftOffice11.0OutlookSecurity
Outlook 2007 – HKEY_CURRENT_USERSoftwareMicrosoftOffice12.0OutlookSecurity
Outlook 2010 -HKEY_CURRENT_USERSoftwareMicrosoftOffice14.0OutlookSecurity
On my install, (I’m running Windows 7 & Microsoft Office 2007) I found the OLK temp folder at:
C:usersMrGrooveAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.OutlookXLCYUT3R
Note: When you open file attachments that are considered safe, Outlook places these attachments in a subdirectory under the your Temporary Internet Files directory as an extra precaution. When Outlook first tries to use a temporary file, it examines the registry to determine whether or not the TEMP OLK folder has already been created. If yes, it uses the folder. If no, it creates a random folder then stores the path in the registry location mentioned above.
