Disable "Always ask before opening" dialog

The box to disable the Open Save dialog is grayed out on Windows 7.

Always ask before opening dialogWe'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.

Run as Administrator

  1. In the Search field on the Start menu, type Outlook.exe
  2. Right click on outlook.exe and choose Run as Administrator.

Run as Administrator dialogTo change make the change permanent or to use this setting for several restarts:

  1. In the Search field on the Start menu, type Outlook.
  2. Right click on Outlook and choose Properties
  3. Select the Compatibility tab and enable Run the programs as an Administrator

When you no longer need administrator permissions you should repeat the steps to disable Run as Administrator.

 

Edit the Registry

Registry EditorThe following keys are for Windows 7. See Restore (or Hide) the Open Save Dialog if you need instructions for older versions of Windows.

DOC: HKEY_CLASSES_ROOT\Word.Document.8
DOCX: HKEY_CLASSES_ROOT\Word.Document.12
PDF: HKEY_CLASSES_ROOT\AcroExch.Document
XLSX: HKEY_CLASSES_ROOT\Excel.Sheet.12
XLS: HKEY_CLASSES_ROOT\Excel.Sheet.8
PPT: HKEY_CLASSES_ROOT\PowerPoint.Show.8
PPTX: HKEY_CLASSES_ROOT\PowerPoint.Show.12

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

Extension keys

EditFlags in the Registry Editor The locate the key by that name. Double click on the EditFlags key to open it for editing.

00 00 00 00 displays the Open or Save dialog
00 00 01 00 opens the file.
