We're
hearing from many users who switched to Windows 7: now
Outlook always prompts for permission to open attachments and the checkbox
for "Always ask before opening this type of file" is grayed out.
This is due to User Access Control (UAC) restrictions in Windows.
There are two ways you can address this: Run Outlook as Administrator
and open the attachments, removing the check from "Always ask before opening this type of file" box.
After you set the desired file types to open without asking, you can run
Outlook normally.
If you know the file types and are comfortable editing the registry or
want to change it via policy, you'll need to identify the file type in
HKEY_CLASSES_ROOT then create or change the EditFlags Data value to 00 00 01
00.
To
change make the change permanent or to use this setting for several
restarts:
When you no longer need administrator permissions you should repeat the steps to disable Run as Administrator.
The
following keys are for Windows 7. See
Restore (or Hide) the Open Save Dialog if you
need instructions for older versions of Windows.

EditFlags: 00 00 01 00
To always ask before opening, either delete the EditFlags value or change the value to 00 00 00 00
Identify Keys for other file types
To identify other file types, look at the extension's key in the registry - most (if not all) will include a more descriptive name. Locate this name under HKEY_CLASSES_ROOT and change it's EditFlags value.
For example, this is the key for the.pptx extension (shown in the
screenshots):
HKEY_CLASSES_ROOT\.ppt\PowerPoint.Show.12
Change the EditFlags value at HKEY_CLASSES_ROOT\PowerPoint.Show.12
The
locate the key by that name. Double click on the EditFlags key to open it
for editing.
