An interesting problem.
Office 2003 Professional was designed primarily for businesses, and Outlook is the business preferred email client, so I wonder if Microsoft have slipped up there, in not giving you the choice.
There is a work around, but I'm not sure it is very satisfactory.
Turn off your internet connection then open Outlook, (it should still be on your system). Outlook will probably say that it is not your default email client and do you wish to make it so. Click "Yes".
In Outlook you may have to import your address book from Outlook Express. I don't see why you wouldn't be able to do that., (but I would make a back-up of the address book first and store it somewhere).
Close down Outlook, open up Word and insert your address.
When done, open up Outlook Express, and it will then ask if you want to make it the default email client. Click Yes.
Like I say, it's a bit cumbersome. Perhaps you would only need to do this once, to set up Word, but I fear not.
I am at my wits' end! I have recently acquired a new PC and have installed Win XP and Office 2003 Professional. I have been using Word 97 (later Word 2000) with Outlook 97 for many years and have had no trouble in accessing my Outlook Contacts address book when I click the 'Insert Address' button in Word. Now when I try it in Word 2003, I get an error message which tells me I
must make Outlook my default mail client. I DO NOT wish to do this - I already use Outlook Express very satisfactorily as my default email handler.
I have spent many hours - nay, days, trying to solve this problem. I have tried the MS Outlook and Word newsgroups, many MS KB articles, the MVP.org website,
Outlook and Word 'Help' folders, etc, etc, etc, but cannot find a solution.
As far as I can see, Outlook 2003 and Word 2003 seem have taken me one step forward and two steps back!
Any help would be much appreciated.
Thanks in advance
