Excel "Sent To" not linking to Global Address List

Hi folks,

Excel 2000 sr1 and Outlook 2000 sr1, (CW install.) When
choosing File Send To in Excel, then clicking on "To", the
GAL is not displayed. Other machines display the GAL
fine. This one displays another dialogue box that I have
not seen before, one that allows you to add contacts but
definately does not link to the GAL.

For the heck of it, I changed the install to Internet Only
then back to Corporate-Workgroup to force it to reinstall
the MAPI subsystem. That had no effect.

TIA,

Rog
