Outlook is undoubtedly one of the most preferred mailboxes but it does come with a few nuances of its own. The one we are going to cover in this segment is the Storage Issues.
Most of us are not aware that Outlook or, as a matter of fact, any other mailbox service stores the temporary files in a folder of your PC.
It’s quite likely that the size of these temporary files will balloon and not only cause performance issues, but also increase the risk of data thefts.
The temporary files include the attachments you view without downloading and the actual attachments that have been opened.
Needless to say, the temporary folder contains sensitive data.

2. Clear Outlook Temporary files by accessing the folders
Thankfully one can directly delete the temp files from the Outlook folders but the issue here is that the temp folder location is stored in registry keys. We have listed the Outlook version along with the name of the key. Just head over to the registry and find the location of the temp files.
- Outlook 2003-HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security
- Outlook 2007-HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security
- Outlook 2010-HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security
- Outlook 2013-HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Security
- Outlook 2016-HKEY_CURRENT_USER\Software\Microsoft\Office16.0\Outlook\Security
In order to access the folder location open OutlookSecureTempFolder registry key and then copy the path from the key. In the next step paste the address in the Address Bar and then press Enter.
Once inside the folder, you can directly delete the temp files.
It’s also worth mentioning that the OutlookTools is yet another cool program that not only lets you delete the temp files in a jiffy but will also give you other powerful features.
We can name an Outlook startup switch, Tweaks to New Mail alert notification, and also an option to unblock the attachments altogether.
On a related note, the Outlook Tools is also a freeware and can be downloaded from here.
