>There were some significant changes between 98 and 2000 when it comes to new properties and events. My guess would be that this error is due to a 2000 property not being interpreted by 98. In that case, I don't think you're gonna get around the problem unless you upgrade them *or* recode the Form in 98 and rely on upward compatibility.

>>Now I have another problem. I used Form converter (Word based) to change a class for my form. I am using Outlook 2000. Users with Outlook 2000 can open my form but users with Outlook 98 have an error message about some problem with a property being used by that form. They click OK and a form gets opened. Any idea? I can upgrade them to 2000 but dont like to give up.

I would think that too. But as I mentioned I used converter (Word macro) to chahge form class. A form designed in 2000 without this converter works fine in 98.
