One of my customers fiddled on its Outlook (Vista Business, Outlook 2007).
Since then all attachments open as PDF, neglecting the proper type of the
attachments. - .doc opens as PDF, .xls opens as PDF ....
Where can I reset the asignements
Thanks, Chris

NB: if they store the attachment and click it afterwards, it opens with the
correct program: pdf as pdf, doc in Word .....

Outlook simply uses what Windows tells it to use. It has no settings apart
from the file type registrations each program installation makes. Do you have
any add-ins that may be autoconverting attachments to PDF?
