Wow! This made my day! I changed the values for Word, Excel and Powerpoint
(".8" for the doc, ppt and xls and ".12" for the Office 2007 files) - and
guess what - it worked!
I will keep this message for further reference and more files types...

Thanks again, this was of great help.
Cheers and Happy New Year
Joerg

This is what I know so far:

In outlook 2007 , the editflags binary value is the key - this example is
for GIF extension. In outlook 2007 SP1, the EditFlags value does not exist
but creating it with 00 00 01 00 data gets rid of the dialog and opens the
message.

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\giffile\EditFl ags
binary data of
00 00 00 00 = always ask (on my SP1 the checkbox to never ask is grayed
out)
00 00 01 00 = always open, no dialog

Word 2007 DOCX extension is
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.Document. 12

Adobe PDF
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AcroExch.Docum ent

I am using the preview-feature. I turned it off to check whether it would
make a difference (after rebooting), but it does not. Sorry.
Does anybody know the respective registry-key which enables/disables the
checkbox?

it's a security feature.

Are you using the feature to view in the reading pane? That negates the
problem for most people.
