Problem

While importing .pst files from external devices in Outlook 2010, "You may not use the file. There is not enough permission to use pst files" error message appears.
You may not use the file. There is not enough permission to use pst files.

Cause

When importing .pst files from an external device in Windows 7 after exporting .pst files from Windows XP to the external device, such problem occurs. The cause of this issue could be that the user accounts for Windows XP and Windows 7 were incompatible or the account control had been improperly set.

Attention
If you use both methods, the security risk may increase. Also, the computer and network may be easily attacked by malicious users and malwares such as viruses. Before applying this change, you might want to evaluate risks relating to the implementation of this step. If you decided to implement this step, take additional measures to keep the system secure.


method 1: Set the permission as "Everyone" on .pst files for import

  1. Right click the .pst file you are about to import and click [Property]. (In this article, backup.pst was used for .pst file as an example.)

    If the problem has been solved, you must restore the User Account Control Setting back to its original step to stop the malicious programs from changing the computer.


Additional Information

The table below outlines how the settings for each step and the settings affect the security.

표 축소표 확대
Setting Description Influence on Security
Always notify
  • Before changing the computer or the Windows within the program which require an administrator permission, a notification message appears.
  • Once you get the notification, the desktop becomes blurred and you can no longer perform other tasks within the computer unless you accept or decline the request displayed in UAC dialog box. When the desktop is in blurred state, no programs can be launched and we call this a "secured desktop".
  • It is the safest setting.
  • If you received the notification, please read the contents in each dialog box before allowing changes on the computer.
Notify only when attempting to change the computer within the program
  • Before changing the computer within the program which requires an administrator permission, a notification message appears.
  • When attempting to change the Windows setting which requires an administrator permission, the notification does not appear.
  • When programs besides Windows try to change the Windows setting, you will see the notification.
  • It is generally safe to allow the change on Windows settings without getting the notification. However, commands or data may be delivered to certain programs provided with Windows, which can be abused by malwares within the computer to install files or change settings. So you should be careful when allowing the programs to be executed on the computer.
Only notify when attempting to change the computer (do not blur the desktop)
  • Before changing the computer within the program which requires an administrator permission, a notification message appears.
  • When attempting to change the Windows setting which requires an administrator permission, the notification does not appear.
  • When programs besides Windows try to change the Windows setting, you will see the notification.
  • This setting is identical to "Notify only when attempting to change the computer within the program" but the notification is not displayed on secured desktop.
  • If you use this setting, other programs may negatively affect the visualization of the dialog box since the UAC dialog box does not exist on the secured desktop. If a malware is already running on the computer, this setting can be a bit risky.
Do not notify
  • A notification is not displayed before a change is made on the computer. When logged in as administrator, the program can make unauthorized changes on the computer.
  • If you are logged in as a standard user, all tasks that require an administrator permission are automatically ignored.
  • When selecting this setting, you must restart the computer and finish disabling the UAC. Once the UAC is unselected, the user who is logged in as administrator always has the admin permission.
  • This is the least safe setting. If the UAC is set not to display the notification, the computer can be exposed to security risk.
  • If the UAC is set not to display the notification, you should be careful when running programs because the executed program is able to access the computer with the permission identical to that of the user to read from or change the protected system area, personal user data, saved files and other saved items from the computer. These programs can also communicate and exchange information with all targets associated with the computer including the Internet.
