I have Outlook 2007 on Windows XP. I create PDFs in a program which
displays the PDF for proofing, then I send it out via the "Attach to
Email" command. Once in the compose new message box I can select
contacts by clicking on To, but when I type anthing in the To box, I
do not get the drop down with matching names.

If I open Outlook directly, then compose a new message, I do receive
the drop down with my frequent email recipients.

I upgraded to Adobe Acrobat Reader 8 from version 7 (uninstalled 7),
and still no change. I have applied all the updates that I can find to
Office.

All ideas are appreciated.

Thank you,

John
