A friend of my is currently in a Word training and has the following problem.

Creating a new Mailmerge document with labels in Word by using data from Outlook Contacts. When connecting the Contacts folder to the document, Word asks with contacts folder it should use. The problem is that this question seems te be random. Because if he creates a new document and wants to connect an Outlook Contacts folder to it, then the question of the contacts folders may or may not appear!

Is this a know bug or is something else wrong?
