Indeed WMS seems to be involved.

    Only this seems to happen only at those workstations that formative is installed.

    How can WMS been set back.

    What I mean wit ‘disappear’ None off the existing adress book are listed. In fact none are listed at all. And all option (to import adressbook ea) are grayed out.

    Formative may not use WMS but it has surely an influence on it. I have hard to understand you did not minimal testing with Outlook Express.

    Tanks for your clear answer,
