If you use Outlook on Windows 7 and open email attachments, you have probably seen the dialog that asks if you want to open or save the attachment after double clicking on the attachment. The option to disable the dialog (and always open attachments) is grayed out, so you can’t get rid of the dialog.
The ‘always ask’ option is grayed out due to security restrictions and User Access Control (UAC). You can Run Outlook as an administrator and answer the dialogs – open all the common file types you get by email, deselect the ‘always ask’ option and restart Outlook using normal permissions.
To run Outlook with Administrator permissions, close Outlook then type Outlook.exe in the start menu’s Search field. Right click on Outlook.exe and choose Run as Administrator.
You can also edit the registry to remove the dialog. See Disable “Always ask before opening” for more information.
