Word 2003 prompts File Conversion when trying to open a document sent from a Mac.

I received a document sent from a Mac that prompted a XP's Word 2003 SP3 install to prompt the for File Conversion, to select the encoding that makes your document readable. The document isn't damaged, but removing the Outlook Security update below, appears to correct the issue. The update itself isn't the cause entirely, as I have another XP machine with the same update installed and it opens the document fine, but I'm using Outlook 2007 on that machine.

It is only an issue with so far with PC's receiving Word docs from Mac users. The issue occurs after the Outlook update KB945432. Hopefully MS is address it soon.

Here's are the steps if anyone should need them

Apply the following HotFix Description of the Outlook 2003 hotfix package: April 15, 2008, which is referenced in the following links as well: In Office Outlook 2003, you cannot open Macintosh binary attachments after you install security update MS08-15 and MS08-015: Description of the security update for Outlook 2003: March 11, 2008

The hotfix above resolved the issue for me on a fully update WinXP box running a fully update install of Office 2003 Pro. The below solution of removing the initial security fix also fixed the problem, I suppose you can still take this route if the hotfix doesn't work. I would try the hotfix first.

1. Go into add/remove program in the control panel.
2. Make sure the 'show updates' is selected on the top of the window.
3. Scroll down to the Microsoft office installation area.
4. Remove the entry listed as 'Outlook 2003 Security update KB945432'
